FULL PRESCRIBING INFORMATION

WARNING: RISK OF RESPIRATORY DEPRESSION, MEDICATION ERRORS, ABUSE POTENTIAL

RESPIRATORY DEPRESSION

Fatal respiratory depression has occurred in patients treated with oral transmucosal fentanyl citrate, including following use in opioid non-tolerant patients and improper dosing. The substitution of oral transmucosal fentanyl citrate for any other fentanyl product may result in fatal overdose.

Due to the risk of respiratory depression, oral transmucosal fentanyl citrate is contraindicated in the management of acute or postoperative pain including headache/migraine and in opioid non-tolerant patients [see Contraindications (4)].

Death has been reported in children who have accidentally ingested oral transmucosal fentanyl citrate. Oral transmucosal fentanyl citrate must be kept out of reach of children [see Patient Counseling Information (17.3) and How Supplied/Storage and Handling (16.1)].

The concomitant use of oral transmucosal fentanyl citrate with CYP3A4 inhibitors may result in an increase in fentanyl plasma concentrations, and may cause potentially fatal respiratory depression [see Drug Interactions (7)].

MEDICATION ERRORS

Substantial differences exist in the pharmacokinetic profile of oral transmucosal fentanyl citrate compared to other fentanyl products that result in clinically important differences in the extent of absorption of fentanyl that could result in fatal overdose.

  • When prescribing, do not convert patients on a mcg per mcg basis from any other fentanyl products to oral transmucosal fentanyl citrate [see Dosage and Administration (2.1)].
  • When dispensing, do not substitute an oral transmucosal fentanyl citrate prescription for other fentanyl products.

ABUSE POTENTIAL

Oral transmucosal fentanyl citrate contains fentanyl, an opioid agonist and a Schedule II controlled substance, with an abuse liability similar to other opioid analgesics. Oral transmucosal fentanyl citrate can be abused in a manner similar to other opioid agonists, legal or illicit. This should be considered when prescribing or dispensing oral transmucosal fentanyl citrate in situations where the physician or pharmacist is concerned about an increased risk of misuse, abuse or diversion.

Because of the risk for misuse, abuse, addiction, and overdose, oral transmucosal fentanyl citrate is available only through a restricted program, required by the Food and Drug Administration, called a Risk Evaluation and Mitigation Strategy (REMS). Under the Transmucosal Immediate Release Fentanyl (TIRF) REMS Access program, outpatients, healthcare professionals who prescribe to outpatients, pharmacies, and distributors must enroll in the program [see Warnings and Precautions (5.10)]. Further information is available at www.TIRFREMSaccess.com or by calling 1-866-822-1483.

1 INDICATIONS AND USAGE

Oral transmucosal fentanyl citrate is indicated for the management of breakthrough pain in cancer patients 16 years of age and older who are already receiving and who are tolerant to around-the-clock opioid therapy for their underlying persistent cancer pain. Patients considered opioid tolerant are those who are taking around-the-clock medicine consisting of at least 60 mg of oral morphine daily, at least 25 mcg of transdermal fentanyl/hour, at least 30 mg of oral oxycodone daily, at least 8 mg of oral hydromorphone daily, at least 25 mg oral oxymorphone daily, or an equianalgesic dose of another opioid daily for a week or longer. Patients must remain on around-the-clock opioids when taking oral transmucosal fentanyl citrate.

This product must not be used in opioid non-tolerant patients because life-threatening respiratory depression and death could occur at any dose in patients not on a chronic regimen of opioids. For this reason, oral transmucosal fentanyl citrate is contraindicated in the management of acute or postoperative pain.

Oral transmucosal fentanyl citrate is intended to be used only in the care of opioid-tolerant cancer patients and only by oncologists and pain specialists who are knowledgeable of and skilled in the use of Schedule II opioids to treat cancer pain.

Limitations of Use:
As a part of the Transmucosal Immediate Release Fentanyl (TIRF) REMS Access program, oral transmucosal fentanyl citrate may be dispensed only to outpatients enrolled in the program [see Warnings and Precautions (5.10)]. For inpatient administration of oral transmucosal fentanyl citrate (e.g. hospitals, hospices, and long-term care facilities that prescribe for inpatient use), patient and prescriber enrollment is not required.

2 DOSAGE AND ADMINISTRATION

Healthcare professionals who prescribe oral transmucosal fentanyl citrate on an outpatient basis must enroll in the TIRF REMS Access program and comply with the requirements of the REMS to ensure safe use of oral transmucosal fentanyl citrate [see Warnings and Precautions (5.10)].

As with all opioids, the safety of patients using such products is dependent on health care professionals prescribing them in strict conformity with their approved labeling with respect to patient selection, dosing, and proper conditions for use.

2.1 Initial Dose

Individually titrate oral transmucosal fentanyl citrate to a dose that provides adequate analgesia and minimizes side effects. The initial dose of oral transmucosal fentanyl citrate to treat episodes of breakthrough cancer pain is always 200 mcg. The oral transmucosal fentanyl citrate unit should be consumed over 15 minutes. Patients should be prescribed an initial titration supply of six 200 mcg oral transmucosal fentanyl citrate units, thus limiting the number of units in the home during titration. Patients should use up all units before increasing to a higher dose to prevent confusion and possible overdose.

2.2 Dose Titration

From this initial dose, closely follow patients and change the dosage level until the patient reaches a dose that provides adequate analgesia using a single oral transmucosal fentanyl citrate dosage unit per breakthrough cancer pain episode. If signs of excessive opioid effects appear before the unit is consumed, the dosage unit should be removed from the patient’s mouth immediately, disposed of properly, and subsequent doses should be decreased. Patients should record their use of oral transmucosal fentanyl citrate over several episodes of breakthrough cancer pain and review their experience with their physicians to determine if a dosage adjustment is warranted.

In cases where the breakthrough pain episode is not relieved 15 minutes after completion of the oral transmucosal fentanyl citrate unit (30 minutes after the start of the unit), patients may take ONLY ONE additional dose of the same strength for that episode. Thus, patients should take a maximum of two doses of oral transmucosal fentanyl citrate for any breakthrough pain episode.

Patients must wait at least 4 hours before treating another episode of breakthrough pain with oral transmucosal fentanyl citrate. To reduce the risk of overdosing during titration, patients should have only one strength of oral transmucosal fentanyl citrate available at any one time.

2.3 Maintenance Dosing

Once titrated to an effective dose, patients should generally use ONLY ONE oral transmucosal fentanyl citrate unit of the appropriate strength per breakthrough pain episode.

On those occasions when the breakthrough pain episode is not relieved 15 minutes after completion of the oral transmucosal fentanyl citrate unit, patient may take ONLY ONE additional dose using the same strength for that episode.

Patients MUST wait at least 4 hours before treating another episode of breakthrough pain with oral transmucosal fentanyl citrate. Once a successful dose has been found (i.e., an average episode is treated with a single unit), patients should limit consumption to four or fewer units per day.

Dosage adjustment of oral transmucosal fentanyl citrate may be required in some patients in order to continue to provide adequate relief of breakthrough pain.

Generally, the oral transmucosal fentanyl citrate dose should be increased only when a single administration of the current dose fails to adequately treat the breakthrough pain episode for several consecutive episodes.

If the patient experiences greater than four breakthrough pain episodes per day, the dose of the maintenance (around-the-clock) opioid used for persistent pain should be re-evaluated.

2.4 Administration of Oral Transmucosal Fentanyl Citrate

Open the blister package with scissors immediately prior to product use. The patient should place the oral transmucosal fentanyl citrate unit in his or her mouth between the cheek and lower gum, occasionally moving the drug matrix from one side to the other using the handle. The oral transmucosal fentanyl citrate unit should be sucked, not chewed. A unit dose of oral transmucosal fentanyl citrate, if chewed and swallowed, might result in lower peak concentrations and lower bioavailability than when consumed as directed [see Clinical Pharmacology (12.3)].

The oral transmucosal fentanyl citrate unit should be consumed over a 15-minute period. Longer or shorter consumption times may produce less efficacy than reported in oral transmucosal fentanyl citrate clinical trials. If signs of excessive opioid effects appear before the unit is consumed, remove the drug matrix from the patient’s mouth immediately and decrease future doses.

2.5 Discontinuation of Oral Transmucosal Fentanyl Citrate

For patients requiring discontinuation of opioids, a gradual downward titration is recommended because it is not known at what dose level the opioid may be discontinued without producing the signs and symptoms of abrupt withdrawal.

3 DOSAGE FORMS AND STRENGTHS

Each dosage unit has white to off-white color and is a solid drug matrix on a handle. Each strength is marked on the individual solid drug matrix and the handle tag [see How Supplied/Storage and Handling (16.3)].

4 CONTRAINDICATIONS

Oral transmucosal fentanyl citrate is contraindicated in opioid non-tolerant patients. Oral transmucosal fentanyl citrate is contraindicated in the management of acute or postoperative pain including headache/migraine. Life-threatening respiratory depression and death could occur at any dose in opioid non-tolerant patients.

Patients considered opioid tolerant are those who are taking around-the-clock medicine consisting of at least 60 mg of oral morphine daily, at least 25 mcg of transdermal fentanyl/hour, at least 30 mg of oral oxycodone daily, at least 8 mg of oral hydromorphone daily, at least 25 mg oral oxymorphone daily, or an equianalgesic dose of another opioid daily for a week or longer.

Oral transmucosal fentanyl citrate is contraindicated in patients with known intolerance or hypersensitivity to any of its components or the drug fentanyl. Anaphylaxis and hypersensitivity have been reported in association with the use of oral transmucosal fentanyl citrate.

5 WARNINGS AND PRECAUTIONS

See Boxed Warning – WARNING: RISK OF RESPIRATORY DEPRESSION, MEDICATION ERRORS, ABUSE POTENTIAL

5.1 Respiratory Depression

Respiratory depression is the chief hazard of opioid agonists, including fentanyl, the active ingredient in oral transmucosal fentanyl citrate. Respiratory depression is more likely to occur in patients with underlying respiratory disorders and elderly or debilitated patients, usually following large initial doses in opioid non-tolerant patients, or when opioids are given in conjunction with other drugs that depress respiration.

Respiratory depression from opioids is manifested by a reduced urge to breathe and a decreased rate of respiration, often associated with the “sighing” pattern of breathing (deep breaths separated by abnormally long pauses). Carbon dioxide retention from opioid-induced respiratory depression can exacerbate the sedating effects of opioids. This makes overdoses involving drugs with sedative properties and opioids especially dangerous.

5.2 Important Information Regarding Prescribing and Dispensing

When prescribing, DO NOT convert a patient to oral transmucosal fentanyl citrate from any other fentanyl product on a mcg per mcg basis as oral transmucosal fentanyl citrate and other fentanyl products are not equivalent on a microgram per microgram basis.

Oral transmucosal fentanyl citrate is NOT a generic version of Fentora® (fentanyl citrate buccal tablet). When dispensing, DO NOT substitute an oral transmucosal fentanyl citrate prescription for a Fentora prescription under any circumstances. Fentora and oral transmucosal fentanyl citrate are not equivalent. Substantial differences exist in the pharmacokinetic profile of oral transmucosal fentanyl citrate compared to other fentanyl products including Fentora that result in clinically important differences in the rate and extent of absorption of fentanyl. As a result of these differences, the substitution of oral transmucosal fentanyl citrate for any other fentanyl product may result in a fatal overdose.

There are no safe conversion directions available for patients on any other fentanyl products. (Note: This includes oral, transdermal, or parenteral formulations of fentanyl.) Therefore, for opioid tolerant patients, the initial dose of oral transmucosal fentanyl citrate should always be 200 mcg. Each patient should be individually titrated to provide adequate analgesia while minimizing side effects [see Dosage and Administration (2.2)].

5.3 Patient/Caregiver Instructions

Patients and their caregivers must be instructed that oral transmucosal fentanyl citrate contains a medicine in an amount which can be fatal to a child. Death has been reported in children who have accidentally ingested oral transmucosal fentanyl citrate. Patients and their caregivers must be instructed to keep both used and unused dosage units out of the reach of children. While all units should be disposed of immediately after use, partially consumed units represent a special risk to children. In the event that a unit is not completely consumed it must be properly disposed as soon as possible [see How Supplied/Storage and Handling (16.1, 16.2), Patient Counseling Information (17.3) and Medication Guide].

Physicians and dispensing pharmacists must specifically question patients or caregivers about the presence of children in the home (on a full time or visiting basis) and counsel them regarding the dangers to children from inadvertent exposure.

Oral transmucosal fentanyl citrate could be fatal to individuals for whom it is not prescribed and for those who are not opioid-tolerant.

5.4 Additive CNS Depressant Effects

The concomitant use of oral transmucosal fentanyl citrate with other CNS depressants, including other opioids, sedatives or hypnotics, general anesthetics, phenothiazines, tranquilizers, skeletal muscle relaxants, sedating antihistamines, and alcoholic beverages may produce increased depressant effects (e.g., respiratory depression, hypotension, and profound sedation). Concomitant use with potent inhibitors of cytochrome P450 3A4 isoform (e.g., erythromycin, ketoconazole, and certain protease inhibitors) may increase fentanyl levels, resulting in increased depressant effects [see Drug Interactions (7)].

Patients on concomitant CNS depressants must be monitored for a change in opioid effects. Consideration should be given to adjusting the dose of oral transmucosal fentanyl citrate if warranted.

5.5 Effects on Ability to Drive and Use Machines

Opioid analgesics impair the mental and/or physical ability required for the performance of potentially dangerous tasks (e.g., driving a car or operating machinery). Warn patients taking oral transmucosal fentanyl citrate of these dangers and counsel them accordingly.

5.6 Chronic Pulmonary Disease

Because potent opioids can cause respiratory depression, titrate oral transmucosal fentanyl citrate with caution in patients with chronic obstructive pulmonary disease or pre-existing medical conditions predisposing them to respiratory depression. In such patients, even normal therapeutic doses of oral transmucosal fentanyl citrate may further decrease respiratory drive to the point of respiratory failure.

5.7 Head Injuries and Increased Intracranial Pressure

Administer oral transmucosal fentanyl citrate with extreme caution in patients who may be particularly susceptible to the intracranial effects of CO2 retention such as those with evidence of increased intracranial pressure or impaired consciousness. Opioids may obscure the clinical course of a patient with a head injury and should be used only if clinically warranted.

5.8 Cardiac Disease

Intravenous fentanyl may produce bradycardia. Therefore, use oral transmucosal fentanyl citrate with caution in patients with bradyarrhythmias.

5.9 MAO Inhibitors

Oral transmucosal fentanyl citrate is not recommended for use in patients who have received MAO inhibitors within 14 days, because severe and unpredictable potentiation by MAO inhibitors has been reported with opioid analgesics.

5.10 Transmucosal Immediate Release Fentanyl (TIRF) Risk Evaluation and Mitigation Strategy (REMS) Access Program

Because of the risk for misuse, abuse, addiction, and overdose [see Drug Abuse and Dependence (9)] oral transmucosal fentanyl citrate is available only through a restricted program called the TIRF REMS Access program. Under the TIRF REMS Access program, outpatients, healthcare professionals who prescribe for outpatient use, pharmacies and distributors must enroll in the program. For inpatient administration (e.g. hospitals, hospices and long-term care facilities that prescribe for inpatient use) of oral transmucosal fentanyl citrate, patient and prescriber enrollment is not required.

Required components of the TIRF REMS Access program are:

  • Healthcare professionals, who prescribe oral transmucosal fentanyl citrate for outpatient use, must review the prescriber educational materials for the TIRF REMS Access program, enroll in the program, and comply with the REMS requirements.
  • To receive oral transmucosal fentanyl citrate, outpatients must understand the risks and benefits and sign a Patient-Prescriber Agreement.
  • Pharmacies that dispense oral transmucosal fentanyl citrate must enroll in the program, and agree to comply with the REMS requirements.
  • Wholesalers and distributors, that distribute oral transmucosal fentanyl citrate must enroll in the program, and distribute only to authorized pharmacies.

Further information, including a list of qualified pharmacies/distributors, is available at www.TIRFREMSaccess.com or by calling 1-866-822-1483.

6 ADVERSE REACTIONS

6.1 Clinical Studies Experience

The safety of oral transmucosal fentanyl citrate has been evaluated in 257 opioid-tolerant chronic cancer pain patients. The duration of oral transmucosal fentanyl citrate use varied during the open-label study. Some patients were followed for over 21 months. The average duration of therapy in the open-label study was 129 days.

The adverse reactions seen with oral transmucosal fentanyl citrate are typical opioid side effects. Frequently, these adverse reactions will cease or decrease in intensity with continued use of oral transmucosal fentanyl citrate, as the patient is titrated to the proper dose. Expect opioid side effects and manage them accordingly.

The most serious adverse reactions associated with all opioids including oral transmucosal fentanyl citrate are respiratory depression (potentially leading to apnea or respiratory arrest), circulatory depression, hypotension, and shock. Follow all patients for symptoms of respiratory depression.

Because the clinical trials of oral transmucosal fentanyl citrate were designed to evaluate safety and efficacy in treating breakthrough cancer pain, all patients were also taking concomitant opioids, such as sustained-release morphine or transdermal fentanyl, for their persistent cancer pain. The adverse event data presented here reflect the actual percentage of patients experiencing each adverse effect among patients who received oral transmucosal fentanyl citrate for breakthrough cancer pain along with a concomitant opioid for persistent cancer pain. There has been no attempt to correct for concomitant use of other opioids, duration of oral transmucosal fentanyl citrate therapy, or cancer-related symptoms. Adverse reactions are included regardless of causality or severity.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Three short-term clinical trials with similar titration schemes were conducted in 257 patients with malignancy and breakthrough cancer pain. Data are available for 254 of these patients. The goal of titration in these trials was to find the dose of oral transmucosal fentanyl citrate that provided adequate analgesia with acceptable side effects (successful dose). Patients were titrated from a low dose to a successful dose in a manner similar to current titration dosing guidelines. Table 1 lists, by dose groups, adverse reactions with an overall frequency of 1% or greater that occurred during titration and are commonly associated with opioid administration or are of particular clinical interest. The ability to assign a dose-response relationship to these adverse reactions is limited by the titration schemes used in these studies. Adverse reactions are listed in descending order of frequency within each body system.

6.2 Postmarketing Experience

Adverse reactions are reported voluntarily from a population of uncertain size, and, therefore, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Decisions to include these reactions in labeling are typically based on one or more of the following factors: (1) seriousness of the reaction, (2) frequency of the reporting, or (3) strength of causal connection to oral transmucosal fentanyl citrate.

The following adverse reactions have been identified during postapproval use of oral transmucosal fentanyl citrate (which contains approximately 2 grams of sugar per unit):

  •   Digestive: Dental decay of varying severity including dental caries, tooth loss, and gum line erosion.
  •   General Disorders and Administration Site Conditions: Application site reactions including irritation, pain, and ulcer.

7 DRUG INTERACTIONS

Fentanyl is metabolized mainly via the human cytochrome P450 3A4 isoenzyme system (CYP3A4); therefore potential interactions may occur when oral transmucosal fentanyl citrate is given concurrently with agents that affect CYP3A4 activity. The concomitant use of oral transmucosal fentanyl citrate with strong CYP3A4 inhibitors (e.g., ritonavir, ketoconazole, itraconazole, troleandomycin, clarithromycin, nelfinavir, and nefazodone) or moderate CYP3A4 inhibitors (e.g., amprenavir, aprepitant, diltiazem, erythromycin, fluconazole, fosamprenavir, and verapamil) may result in increased fentanyl plasma concentrations, potentially causing serious adverse drug effects including fatal respiratory depression. Patients receiving oral transmucosal fentanyl citrate concomitantly with moderate or strong CYP3A4 inhibitors should be carefully monitored for an extended period of time. Dosage increase should be done conservatively.

Grapefruit and grapefruit juice decrease CYP3A4 activity, increasing blood concentrations of fentanyl, thus should be avoided.

Drugs that induce cytochrome P450 3A4 activity may have the opposite effects.

Concomitant use of oral transmucosal fentanyl citrate with an MAO inhibitor, or within 14 days of discontinuation, is not recommended [see Warnings and Precautions (5.9)].

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category C

There are no adequate and well-controlled studies in pregnant women. Oral transmucosal fentanyl citrate should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. No epidemiological studies of congenital anomalies in infants born to women treated with fentanyl during pregnancy have been reported.

Chronic maternal treatment with fentanyl during pregnancy has been associated with transient respiratory depression, behavioral changes, or seizures in newborn infants characteristic of neonatal abstinence syndrome.

In women treated acutely with intravenous or epidural fentanyl during labor, symptoms of neonatal respiratory or neurological depression were no more frequent than would be expected in infants of untreated mothers.

Transient neonatal muscular rigidity has been observed in infants whose mothers were treated with intravenous fentanyl.

Fentanyl is embryocidal in rats as evidenced by increased resorptions in pregnant rats at doses of 30 mcg/kg IV or 160 mcg/kg SC. Conversion to human equivalent doses indicates this is within the range of the human recommended dosing for oral transmucosal fentanyl citrate.

Fentanyl citrate was not teratogenic when administered to pregnant animals. Published studies demonstrated that administration of fentanyl (10, 100, or 500 mcg/kg/day) to pregnant rats from day 7 to 21, of their 21 day gestation, via implanted microosmotic minipumps was not teratogenic (the high dose was approximately 3-times the human dose of 1600 mcg per pain episode on a mg/m2 basis). Intravenous administration of fentanyl (10 or 30 mcg/kg) to pregnant female rats from gestation day 6 to 18, was embryo or fetal toxic, and caused a slightly increased mean delivery time in the 30 mcg/kg/day group, but was not teratogenic.

8.2 Labor and Delivery

Fentanyl readily passes across the placenta to the fetus; therefore do not use oral transmucosal fentanyl citrate during labor and delivery (including caesarean section) since it may cause respiratory depression in the fetus or in the newborn infant.

8.3 Nursing Mothers

Fentanyl is excreted in human milk; therefore, do not use oral transmucosal fentanyl citrate in nursing women because of the possibility of sedation and/or respiratory depression in their infants. Symptoms of opioid withdrawal may occur in infants at the cessation of nursing by women using oral transmucosal fentanyl citrate.

8.4 Pediatric Use

Safety and effectiveness in pediatric patients below 16 years of age have not been established.

In a clinical study, 15 opioid-tolerant pediatric patients with breakthrough pain, ranging in age from 5 to 15 years, were treated with oral transmucosal fentanyl citrate. The study was too small to allow conclusions on safety and efficacy in this patient population. Twelve of the fifteen opioid-tolerant children and adolescents aged 5 to 15 years in this study received oral transmucosal fentanyl citrate at doses ranging from 200 mcg to 600 mcg. The mean (CV%; range) dose-normalized (to 200 mcg) Cmax and AUC0-8 values were 0.87 ng/mL (51%; 0.42-1.30) and 4.54 ng·h/mL (42%; 2.37-6.0), respectively, for children ages 5 to <11 years old (N = 3) and 0.68 ng/mL (72%; 0.15-1.44) and 8.38 (192%; 0.84-50.78), respectively, for children ages ≥11 to <16 y (N = 9).

8.5 Geriatric Use

Of the 257 patients in clinical studies of oral transmucosal fentanyl citrate in breakthrough cancer pain, 61 (24%) were 65 years of age and older, while 15 (6%) were 75 years of age and older. Those patients over the age of 65 years were titrated to a mean dose that was about 200 mcg less than the mean dose titrated to by younger patients. No difference was noted in the safety profile of the group over 65 years of age as compared to younger patients in oral transmucosal fentanyl citrate clinical trials.

Elderly patients have been shown to be more sensitive to the effects of fentanyl when administered intravenously, compared with the younger population. Therefore, exercise caution when individually titrating oral transmucosal fentanyl citrate in elderly patients to provide adequate efficacy while minimizing risk.

8.6 Patients with Renal or Hepatic Impairment

Insufficient information exists to make recommendations regarding the use of oral transmucosal fentanyl citrate in patients with impaired renal or hepatic function. Fentanyl is metabolized primarily via human cytochrome P450 3A4 isoenzyme system and mostly eliminated in urine. If the drug is used in these patients, it should be used with caution because of the hepatic metabolism and renal excretion of fentanyl.

8.7 Gender

Both male and female opioid-tolerant cancer patients were studied for the treatment of breakthrough cancer pain. No clinically relevant gender differences were noted either in dosage requirement or in observed adverse reactions.

9 DRUG ABUSE AND DEPENDENCE

9.1 Controlled Substance

Fentanyl is a Schedule II controlled substance that can produce drug dependence of the morphine type. Oral transmucosal fentanyl citrate may be subject to misuse, abuse and addiction.

9.2 Abuse and Addiction

Manage the handling of oral transmucosal fentanyl citrate to minimize the risk of diversion, including restriction of access and accounting procedures as appropriate to the clinical setting and as required by law [see How Supplied/Storage and Handling (16.1, 16.2)].

Concerns about abuse, addiction, and diversion should not prevent the proper management of pain. However, all patients treated with opioids require careful monitoring for signs of abuse and addiction, because use of opioid analgesic products carries the risk of addiction even under appropriate medical use.

Addiction is a primary, chronic, neurobiologic disease, with genetic, psychosocial, and environmental factors influencing its development and manifestations. It is characterized by behaviors that include one or more of the following: impaired control over drug use, compulsive use, continued use despite harm, and craving. Drug addiction is a treatable disease, utilizing a multidisciplinary approach, but relapse is common. “Drug-seeking” behavior is very common in addicts and drug abusers.

Abuse and addiction are separate and distinct from physical dependence and tolerance. Physicians should be aware that addiction may not be accompanied by concurrent tolerance and symptoms of physical dependence in all addicts. In addition, abuse of opioids can occur in the absence of addiction and is characterized by misuse for nonmedical purposes, often in combination with other psychoactive substances. Since oral transmucosal fentanyl citrate may be diverted for non-medical use, careful record keeping of prescribing information, including quantity, frequency, and renewal requests is strongly advised.

Proper assessment of patients, proper prescribing practices, periodic re-evaluation of therapy, and proper dispensing and storage are appropriate measures that help to limit abuse of opioid drugs.

Healthcare professionals should contact their State Professional Licensing Board, or State Controlled Substances Authority for information on how to prevent and detect abuse or diversion of this product.

9.3 Dependence

Guide the administration of oral transmucosal fentanyl citrate by the response of the patient. Physical dependence, per se, is not ordinarily a concern when one is treating a patient with chronic cancer pain, and fear of tolerance and physical dependence should not deter using doses that adequately relieve the pain.

Opioid analgesics may cause physical dependence. Physical dependence results in withdrawal symptoms in patients who abruptly discontinue the drug. Withdrawal also may be precipitated through the administration of drugs with opioid antagonist activity, e.g., naloxone, nalmefene, or mixed agonist/antagonist analgesics (pentazocine, butorphanol, buprenorphine, nalbuphine).

Physical dependence usually does not occur to a clinically significant degree until after several weeks of continued opioid usage. Tolerance, in which increasingly larger doses are required in order to produce the same degree of analgesia, is initially manifested by a shortened duration of analgesic effect, and subsequently, by decreases in the intensity of analgesia.

10 OVERDOSAGE

10.1 Clinical Presentation

The manifestations of oral transmucosal fentanyl citrate overdosage are expected to be similar in nature to intravenous fentanyl and other opioids, and are an extension of its pharmacological actions with the most serious significant effect being respiratory depression [see Clinical Pharmacology (12.2)].

10.2 Immediate Management

Immediate management of opioid overdose includes removal of the oral transmucosal fentanyl citrate unit, if still in the mouth, ensuring a patent airway, physical and verbal stimulation of the patient, and assessment of level of consciousness, ventilatory and circulatory status.

10.3 Treatment of Overdosage (Accidental Ingestion) in the Opioid NON-Tolerant Person

Provide ventilatory support, obtain intravenous access, and employ naloxone or other opioid antagonists as clinically indicated. The duration of respiratory depression following overdose may be longer than the effects of the opioid antagonist's action (e.g., the half-life of naloxone ranges from 30 to 81 minutes) and repeated administration may be necessary. Consult the package insert of the individual opioid antagonist for details about such use.

10.4 Treatment of Overdose in Opioid-Tolerant Patients

Provide ventilatory support and obtain intravenous access as clinically indicated. Judicious use of naloxone or another opioid antagonist may be warranted in some instances, but it is associated with the risk of precipitating an acute withdrawal syndrome.

10.5 General Considerations for Overdose

Management of severe oral transmucosal fentanyl citrate overdose includes: securing a patent airway, assisting or controlling ventilation, establishing intravenous access, and GI decontamination by lavage and/or activated charcoal, once the patient's airway is secure. In the presence of respiratory depression or apnea, assist or control ventilation, and administer oxygen as indicated.

Although muscle rigidity interfering with respiration has not been seen following the use of oral transmucosal fentanyl citrate, this is possible with fentanyl and other opioids. If it occurs, manage it by using assisted or controlled ventilation, by an opioid antagonist, and as a final alternative, by a neuromuscular blocking agent.

11 DESCRIPTION

Oral transmucosal fentanyl citrate is a solid formulation of fentanyl citrate, a potent opioid analgesic, intended for oral transmucosal administration. Oral transmucosal fentanyl citrate is formulated as a white to off-white solid drug matrix on a handle that is fracture resistant (ABS plastic) under normal conditions when used as directed.

Oral transmucosal fentanyl citrate is designed to be dissolved slowly in the mouth to facilitate transmucosal absorption. The handle allows the oral transmucosal fentanyl citrate unit to be removed from the mouth if signs of excessive opioid effects appear during administration.

Active Ingredient: Fentanyl citrate USP is N-(1-Phenethyl-4-piperidyl) propionanilide citrate (1:1). Fentanyl is a highly lipophilic compound (octanol-water partition coefficient at pH 7.4 is 816:1) that is freely soluble in organic solvents and sparingly soluble in water (1:40). The molecular weight of the free base is 336.5 (the citrate salt is 528.6). The pKa of the tertiary nitrogens are 7.3 and 8.4. The compound has the following structural formula:

Inactive Ingredients: Raspberry flavor, citric acid, confectioners sugar, dextrates, magnesium stearate, dibasic sodium phosphate, modified food starch, ethanol, water, purified shellac, propylene glycol, FD&C blue no. 1, ammonium hydroxide.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Fentanyl is a pure opioid agonist whose principal therapeutic action is analgesia. Other members of the class known as opioid agonists include substances such as morphine, oxycodone, hydromorphone, codeine, and hydrocodone.

12.2 Pharmacodynamics

Pharmacological effects of opioid agonists include anxiolysis, euphoria, feelings of relaxation, respiratory depression, constipation, miosis, cough suppression, and analgesia. Like all pure opioid agonist analgesics, with increasing doses there is increasing analgesia, unlike with mixed agonist/antagonists or non-opioid analgesics, where there is a limit to the analgesic effect with increasing doses. With pure opioid agonist analgesics, there is no defined maximum dose; the ceiling to analgesic effectiveness is imposed only by side effects, the more serious of which may include somnolence and respiratory depression.

Analgesia

The analgesic effects of fentanyl are related to the blood level of the drug, if proper allowance is made for the delay into and out of the CNS (a process with a 3- to 5-minute half-life).

In general, the effective concentration and the concentration at which toxicity occurs increase with increasing tolerance with any and all opioids. The rate of development of tolerance varies widely among individuals. As a result, the dose of oral transmucosal fentanyl citrate should be individually titrated to achieve the desired effect [see Dosage and Administration (2.2)].

Central Nervous System

The precise mechanism of the analgesic action is unknown although fentanyl is known to be a mu-opioid receptor agonist. Specific CNS opioid receptors for endogenous compounds with opioid-like activity have been identified throughout the brain and spinal cord and play a role in the analgesic effects of this drug.

Fentanyl produces respiratory depression by direct action on brain stem respiratory centers. The respiratory depression involves both a reduction in the responsiveness of the brain stem to increases in carbon dioxide and to electrical stimulation.

Fentanyl depresses the cough reflex by direct effect on the cough center in the medulla. Antitussive effects may occur with doses lower than those usually required for analgesia.

Fentanyl causes miosis even in total darkness. Pinpoint pupils are a sign of opioid overdose but are not pathognomonic (e.g., pontine lesions of hemorrhagic or ischemic origin may produce similar findings).

Gastrointestinal System

Fentanyl causes a reduction in motility associated with an increase in smooth muscle tone in the antrum of the stomach and in the duodenum. Digestion of food is delayed in the small intestine and propulsive contractions are decreased. Propulsive peristaltic waves in the colon are decreased, while tone may be increased to the point of spasm resulting in constipation. Other opioid-induced effects may include a reduction in gastric, biliary and pancreatic secretions, spasm of the sphincter of Oddi, and transient elevations in serum amylase.

Cardiovascular System

Fentanyl may produce release of histamine with or without associated peripheral vasodilation. Manifestations of histamine release and/or peripheral vasodilation may include pruritus, flushing, red eyes, sweating, and/or orthostatic hypotension.

Endocrine System

Opioid agonists have been shown to have a variety of effects on the secretion of hormones. Opioids inhibit the secretion of ACTH, cortisol, and luteinizing hormone (LH) in humans. They also stimulate prolactin, growth hormone (GH) secretion, and pancreatic secretion of insulin and glucagon in humans and other species, rats and dogs. Thyroid stimulating hormone (TSH) has been shown to be both inhibited and stimulated by opioids.

Respiratory System

All opioid mu-receptor agonists, including fentanyl, produce dose-dependent respiratory depression. The risk of respiratory depression is less in patients receiving chronic opioid therapy who develop tolerance to respiratory depression and other opioid effects. During the titration phase of the clinical trials, somnolence, which may be a precursor to respiratory depression, did increase in patients who were treated with higher doses of oral transmucosal fentanyl citrate. Peak respiratory depressive effects may be seen as early as 15 to 30 minutes from the start of oral transmucosal fentanyl citrate product administration and may persist for several hours.

Serious or fatal respiratory depression can occur even at recommended doses. Fentanyl depresses the cough reflex as a result of its CNS activity. Although not observed with oral transmucosal fentanyl products in clinical trials, fentanyl given rapidly by intravenous injection in large doses may interfere with respiration by causing rigidity in the muscles of respiration. Therefore, physicians and other healthcare providers should be aware of this potential complication [see Boxed Warning – Warning: Risk of Respiratory Depression, Medication Errors, Abuse Potential, Contraindications (4), Warnings and Precautions (5.2), Adverse Reactions (6), and Overdosage (10)].

12.3 Pharmacokinetics

Absorption

The absorption pharmacokinetics of fentanyl from the oral transmucosal dosage form is a combination of an initial rapid absorption from the buccal mucosa and a more prolonged absorption of swallowed fentanyl from the GI tract. Both the blood fentanyl profile and the bioavailability of fentanyl will vary depending on the fraction of the dose that is absorbed through the oral mucosa and the fraction swallowed.

Absolute bioavailability, as determined by area under the concentration-time curve, of 15 mcg/kg in 12 adult males was 50% compared to intravenous fentanyl.

Normally, approximately 25% of the total dose of oral transmucosal fentanyl citrate is rapidly absorbed from the buccal mucosa and becomes systemically available. The remaining 75% of the total dose is swallowed with the saliva and then is slowly absorbed from the GI tract. About 1/3 of this amount (25% of the total dose) escapes hepatic and intestinal first-pass elimination and becomes systemically available. Thus, the generally observed 50% bioavailability of oral transmucosal fentanyl citrate is divided equally between rapid transmucosal and slower GI absorption. Therefore, a unit dose of oral transmucosal fentanyl citrate, if chewed and swallowed, might result in lower peak concentrations and lower bioavailability than when consumed as directed.

Dose proportionality among four of the available strengths of oral transmucosal fentanyl citrate (200, 400, 800, and 1600 mcg) has been demonstrated in a balanced crossover design in adult subjects (n=11). Mean serum fentanyl levels following these four doses of oral transmucosal fentanyl citrate are shown in Figure 1 . The curves for each dose level are similar in shape with increasing dose levels producing increasing serum fentanyl levels. Cmax and AUC0→∞ increased in a dose-dependent manner that is approximately proportional to the oral transmucosal fentanyl citrate administered.

Figure 1. Mean Serum Fentanyl Concentration (ng/mL) in Adult Subjects Comparing 4 Doses of Oral Transmucosal Fentanyl Citrate

The pharmacokinetic parameters of the four strengths of oral transmucosal fentanyl citrate tested in the dose-proportionality study are shown in Table 3 . The mean Cmax ranged from 0.39 to 2.51 ng/mL. The median time of maximum plasma concentration (Tmax) across these four doses of oral transmucosal fentanyl citrate varied from 20 to 40 minutes (range of 20 to 480 minutes) as measured after the start of administration.

Distribution

Fentanyl is highly lipophilic. Animal data showed that following absorption, fentanyl is rapidly distributed to the brain, heart, lungs, kidneys and spleen followed by a slower redistribution to muscles and fat. The plasma protein binding of fentanyl is 80 to 85%. The main binding protein is alpha-1-acid glycoprotein, but both albumin and lipoproteins contribute to some extent. The free fraction of fentanyl increases with acidosis. The mean volume of distribution at steady state (Vss) was 4 L/kg.

Metabolism

Fentanyl is metabolized in the liver and in the intestinal mucosa to norfentanyl by cytochrome P450 3A4 isoform. Norfentanyl was not found to be pharmacologically active in animal studies [see Drug Interactions (7)].

Elimination

Fentanyl is primarily (more than 90%) eliminated by biotransformation to N-dealkylated and hydroxylated inactive metabolites. Less than 7% of the dose is excreted unchanged in the urine, and only about 1% is excreted unchanged in the feces. The metabolites are mainly excreted in the urine, while fecal excretion is less important. The total plasma clearance of fentanyl was 0.5 L/hr/kg (range 0.3 to 0.7 L/hr/kg). The terminal elimination half-life after oral transmucosal fentanyl citrate administration is about 7 hours.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Long-term studies in animals have not been performed to evaluate the carcinogenic potential of fentanyl.

Fentanyl citrate was not mutagenic in the in vitro Ames reverse mutation assay in S. typhimurium or E. coli, or the mouse lymphoma mutagenesis assay, and was not clastogenic in the in vivo mouse micronucleus assay.

Fentanyl has been shown to impair fertility in rats at doses of 30 mcg/kg IV and 160 mcg/kg subcutaneously. Conversion to the human equivalent doses indicates that this is within the range of the human recommended dosing for oral transmucosal fentanyl citrate.

14 CLINICAL STUDIES

Oral transmucosal fentanyl citrate was investigated in clinical trials involving 257 opioid tolerant adult cancer patients experiencing breakthrough cancer pain. Breakthrough cancer pain was defined as a transient flare of moderate-to-severe pain occurring in cancer patients experiencing persistent cancer pain otherwise controlled with maintenance doses of opioid medications including at least 60 mg morphine/day, 50 mcg transdermal fentanyl/hour, or an equianalgesic dose of another opioid for a week or longer.

In two dose titration studies 95 of 127 patients (75%) who were on stable doses of either long-acting oral opioids or transdermal fentanyl for their persistent cancer pain titrated to a successful dose of oral transmucosal fentanyl citrate to treat their breakthrough cancer pain within the dose range offered (200, 400, 600, 800, 1200 and 1600 mcg). A “successful” dose was defined as a dose where one unit of oral transmucosal fentanyl citrate could be used consistently for at least two consecutive days to treat breakthrough cancer pain without unacceptable side effects. In these studies 11% of patients withdrew due to adverse reactions and 14% withdrew due to other reasons.

The successful dose of oral transmucosal fentanyl citrate for breakthrough cancer pain was not predicted from the daily maintenance dose of opioid used to manage the persistent cancer pain and is thus best determined by dose titration.

A double-blind placebo controlled crossover study was performed in cancer patients to evaluate the effectiveness of oral transmucosal fentanyl citrate for the treatment of breakthrough cancer pain. Of 130 patients who entered the study 92 patients (71%) achieved a successful dose during the titration phase. The distribution of successful doses is shown in Table 4 .

Table 4. Successful Dose of Oral Transmucosal Fentanyl Citrate Following Initial Titration
Oral Transmucosal Fentanyl Citrate Dose Total No. (%)
(N=92)
200 mcg 13 (14)
400 mcg 19 (21)
600 mcg 14 (15)
800 mcg 18 (20)
1200 mcg 13 (14)
1600 mcg 15 (16)
Mean +/- SD 789 +/- 468 mcg

On average, patients over 65 years of age titrated to a mean dose that was about 200 mcg less than the mean dose to which younger adult patients were titrated.

Oral transmucosal fentanyl citrate was administered beginning at Time 0 minutes and produced more pain relief compared with placebo at 15, 30, 45, and 60 minutes as measured after the start of administration (see Figure 2 ). The differences were statistically significant.

  • Instruct patients that they MUST wait at least 4 hours before treating another episode of breakthrough pain with oral transmucosal fentanyl citrate.
  • Instruct patients NOT to share oral transmucosal fentanyl citrate and that sharing oral transmucosal fentanyl citrate with anyone else could result in the other individual’s death due to overdose.
  • Make patients aware that oral transmucosal fentanyl citrate contains fentanyl which is a strong pain medication similar to hydromorphone, methadone, morphine, oxycodone, and oxymorphone.
  • Instruct patients that the active ingredient in oral transmucosal fentanyl citrate, fentanyl, is a drug that some people abuse. Oral transmucosal fentanyl citrate should be taken only by the patient it was prescribed for, and it should be protected from theft or misuse in the work or home environment.
  • Caution patients to talk to their doctor if breakthrough pain is not alleviated or worsens after taking oral transmucosal fentanyl citrate.
  • Instruct patients to use oral transmucosal fentanyl citrate exactly as prescribed by their doctor and not to take oral transmucosal fentanyl citrate more often than prescribed.
  • Caution patients that oral transmucosal fentanyl citrate can affect a person’s ability to perform activities that require a high level of attention (such as driving or using heavy machinery). Warn patients taking oral transmucosal fentanyl citrate of these dangers and counsel them accordingly.
  • Warn patients to not combine oral transmucosal fentanyl citrate with alcohol, sleep aids, or tranquilizers except by the orders of the prescribing physician, because dangerous additive effects may occur, resulting in serious injury or death.
  • Inform female patients that if they become pregnant or plan to become pregnant during treatment with oral transmucosal fentanyl citrate, they should ask their doctor about the effects that oral transmucosal fentanyl citrate (or any medicine) may have on them and their unborn children.
  • Physicians and dispensing pharmacists must specifically question patients or caregivers about the presence of children in the home (on a full time or visiting basis) and counsel them regarding the dangers to children from inadvertent exposure.

17.2 Dental Care

Because each oral transmucosal fentanyl citrate unit contains approximately 2 grams of sugar (hydrated dextrates), frequent consumption may increase the risk of dental decay. The occurrence of dry mouth associated with the use of opioid medications (such as fentanyl) may add to this risk.

Postmarketing reports of dental decay have been received in patients taking oral transmucosal fentanyl citrate [see Adverse Reactions (6.2)]. In some of these patients, dental decay occurred despite reported routine oral hygiene. As dental decay in cancer patients may be multi-factorial, patients using oral transmucosal fentanyl citrate should consult their dentist to ensure appropriate oral hygiene.

17.3 Diabetic Patients

Advise diabetic patients that oral transmucosal fentanyl citrate contains approximately 2 grams of sugar per unit.

17.4 Oral Transmucosal Fentanyl Citrate Child Safety Kit

Provide patients and their caregivers who have children in the home or visiting with an oral transmucosal fentanyl citrate Child Safety Kit, which contains educational materials and safe interim storage containers to help patients store oral transmucosal fentanyl citrate and other medicines out of the reach of children. To obtain a supply of Child Safety Kits, health care professionals can call Mallinckrodt Pharmaceutical Child Safety Kit Request Line, at 1-800-223-1499.

17.5 Disposal of Used Oral Transmucosal Fentanyl Citrate Units

Patients must be instructed to dispose of completely used and partially used oral transmucosal fentanyl citrate units.

  • After consumption of the unit is complete and the matrix is totally dissolved, throw away the handle in a trash container that is out of the reach of children.
  • If any of the drug matrix remains on the handle, place the handle under hot running tap water until all of the drug matrix is dissolved, and then dispose of the handle in a place that is out of the reach of children.
  • Dispose of handles in the child-resistant container (as described in steps 1 and 2) at least once a day.

If the patient does not entirely consume the unit and the remaining drug cannot be immediately dissolved under hot running water, the patient or caregiver must temporarily store the oral transmucosal fentanyl citrate unit in the specially provided child-resistant container out of the reach of children until proper disposal is possible.

17.6 Disposal of Unopened Oral Transmucosal Fentanyl Citrate Units When No Longer Needed

Patients and members of their household must be advised to dispose of any unopened units remaining from a prescription as soon as they are no longer needed.

To dispose of the unused oral transmucosal fentanyl citrate units:

  • Remove the oral transmucosal fentanyl citrate unit from its blister package using scissors, and hold the oral transmucosal fentanyl citrate by its handle over the toilet bowl.
  • Using wire-cutting pliers cut off the drug matrix end so that it falls into the toilet.
  • Dispose of the handle in a place that is out of the reach of children.
  • Repeat steps 1, 2, and 3 for each oral transmucosal fentanyl citrate unit. Flush the toilet twice after 5 units have been cut and deposited into the toilet.

Do not flush the entire oral transmucosal fentanyl citrate units, oral transmucosal fentanyl citrate handles, blister packages, or cartons down the toilet. Dispose of the handle where children cannot reach it [see How Supplied/Storage and Handling (16.1)].

Detailed instructions for the proper storage, administration, disposal, and important instructions for managing an overdose of oral transmucosal fentanyl citrate are provided in the oral transmucosal fentanyl citrate Medication Guide. Encourage patients to read this information in its entirety and give them an opportunity to have their questions answered.

In the event that a caregiver requires additional assistance in disposing of excess unusable units that remain in the home after a patient has expired, instruct them to call the toll-free number for Mallinckrodt Inc., Product Monitoring at 1-800-778-7898, or seek assistance from their local DEA office.

What should I avoid while using oral transmucosal fentanyl citrate?

  • Do not drive, operate heavy machinery, or do other dangerous activities until you know how oral transmucosal fentanyl citrate affects you. Oral transmucosal fentanyl citrate can make you sleepy. Ask your healthcare provider when it is okay to do these activities.
  • Do not drink alcohol while using oral transmucosal fentanyl citrate. It can increase your chance of getting dangerous side effects.

What are the possible side effects of oral transmucosal fentanyl citrate?

Oral transmucosal fentanyl citrate can cause serious side effects, including:

  • Breathing problems that can become life-threatening, See “What is the most important information I should know about oral transmucosal fentanyl citrate?”

    Call your healthcare provider or get emergency medical help right away if you:

    • have trouble breathing
    • have drowsiness with slowed breathing
    • have slow shallow breathing (little chest movement with breathing)
    • feel faint, very dizzy, confused, or have unusual symptoms

    These symptoms can be a sign that you have used too much oral transmucosal fentanyl citrate or the dose is too high for you. These symptoms may lead to serious problems or death if not treated right away. If you have any of these symptoms, do not use any more oral transmucosal fentanyl citrate until you have talked to your healthcare provider.
  • Decreased blood pressure. This can make you feel dizzy or lightheaded if you get up too fast from sitting or lying down.
  • Physical dependence. Do not stop taking oral transmucosal fentanyl citrate or any other opioid without talking to your healthcare provider. You could become sick with uncomfortable withdrawal symptoms because your body has become used to these medicines. Physical dependency is not the same as drug addiction.
  • A chance of abuse or addiction. The chance is higher if you are or have ever been addicted to or abused other medicines, street drugs, or alcohol, or if you have a history of mental health problems.

The most common side effects of oral transmucosal fentanyl citrate are:

  • nausea
  • vomiting
  • dizziness
  • sleepiness
  • weakness
  • headache
  • anxiety
  • confusion
  • depression
  • rash
  • trouble sleeping

Constipation (not often enough or hard bowel movements) is a very common side effect of pain medicines (opioids) including oral transmucosal fentanyl citrate and is unlikely to go away without treatment. Talk to your healthcare provider about dietary changes, and the use of laxatives (medicines to treat constipation) and stool softeners to prevent or treat constipation while taking oral transmucosal fentanyl citrate.

Oral transmucosal fentanyl citrate contains sugar. Cavities and tooth decay can happen in people taking oral transmucosal fentanyl citrate. When taking oral transmucosal fentanyl citrate, you should talk to your dentist about proper care of your teeth.

Tell your healthcare provider if you have any side effect that bothers you or that does not go away.

These are not all the possible side effects of oral transmucosal fentanyl citrate. For more information, ask your healthcare provider or pharmacist.

Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

How should I store oral transmucosal fentanyl citrate?

  • Always keep oral transmucosal fentanyl citrate in a safe place away from children and from anyone for whom it has not been prescribed. Protect oral transmucosal fentanyl citrate from theft.
    • You can use the oral transmucosal fentanyl citrate Child Safety Kit to help you store oral transmucosal fentanyl citrate and your other medicines out of the reach of children.

How should I dispose of oral transmucosal fentanyl citrate when they are no longer needed?

Disposing of oral transmucosal fentanyl citrate units after use:
Partially used oral transmucosal fentanyl citrate units may contain enough medicine to be harmful or fatal to a child or other adults who have not been prescribed oral transmucosal fentanyl citrate. You must properly dispose of the oral transmucosal fentanyl citrate handle right away after use even if there is little or no medicine left on it.

After you have finished the oral transmucosal fentanyl citrate unit and the medicine is totally gone, throw the handle away in a place that is out of the reach of children.

If any medicine remains on the used oral transmucosal fentanyl citrate unit after you have finished:

  • Place the used oral transmucosal fentanyl citrate unit under hot running water until the medicine is gone, and then throw the handle away out of the reach of children and pets (See Figure 4).

Temporary Storage of Used Oral Transmucosal Fentanyl Citrate Units:

  • If you did not finish the entire oral transmucosal fentanyl citrate unit and you cannot dissolve the medicine under hot running water right away, put the used oral transmucosal fentanyl citrate in the temporary storage bottle that you received in the oral transmucosal fentanyl citrate Child Safety Kit. Place the oral transmucosal fentanyl citrate unit into the bottle and secure the cap. Never leave unused or partially used oral transmucosal fentanyl citrate units where children or pets can get to them (See Figure 5).

Disposing of Used Oral Transmucosal Fentanyl Citrate Units from the Temporary Storage Bottle:

You must dispose of all used oral transmucosal fentanyl citrate units in the temporary storage bottle at least one time each day, as follows:

  • To open the temporary storage bottle, push down on the cap until you are able to twist the cap to the left to remove it (See Figure 6).
  • Remove one oral transmucosal fentanyl citrate unit from the temporary storage bottle. Hold the oral transmucosal fentanyl citrate by its handle over the toilet bowl.
  • Using wire-cutting pliers, cut the medicine end off so that it falls into the toilet.
  • Throw the handle away in a place that is out of the reach of children.
  • Repeat these 3 steps for each oral transmucosal fentanyl citrate handle that is in the storage bottle. There should not be more than 4 handles in the temporary storage bottle for 1 day.
  • Flush the toilet twice.

Do not flush entire unused oral transmucosal fentanyl citrate units, oral transmucosal fentanyl citrate handles, or blister packages down the toilet.

Disposing of unopened oral transmucosal fentanyl citrate units: Dispose of any unopened oral transmucosal fentanyl citrate units remaining from a prescription as soon as they are no longer needed, as follows:

  • Remove all oral transmucosal fentanyl citrate from the locked storage space (See Figure 7).
  • Remove one oral transmucosal fentanyl citrate unit from its blister package by using scissors to cut off the marked end and then peel back the blister backing (See Figures 8A and 8B).
  • Hold oral transmucosal fentanyl citrate by its handle over the toilet bowl. Use wire-cutting pliers to cut the medicine end off so that it falls into the toilet (See Figures 9A and 9B).
  • Throw the handle away in a place that is out of the reach of children (See Figure 10).
  • Repeat steps 1 through 4 for each oral transmucosal fentanyl citrate unit.
  • Flush the toilet twice after the medicine ends from 5 oral transmucosal fentanyl citrate units have been cut off (See Figure 11). Do not flush more than 5 oral transmucosal fentanyl citrate units at a time.
    • Do not flush entire unused oral transmucosal fentanyl citrate units, oral transmucosal fentanyl citrate handles, or blister packages down the toilet.

If you need help with the disposal of oral transmucosal fentanyl citrate, call Mallinckrodt Inc., Product Monitoring at 1-800-778-7898, or call your local Drug Enforcement Agency (DEA) office.
