FULL PRESCRIBING INFORMATION

1 INDICATIONS AND USAGE

Oxycodone hydrochloride capsule is an opioid analgesic, indicated for the management of moderate to severe acute and chronic pain where use of an opioid analgesic is appropriate.

2 DOSAGE AND ADMINISTRATION

Selection of patients for treatment with oxycodone hydrochloride should be governed by the same principles that apply to the use of similar opioid analgesics. Individualize treatment in every case, using non-opioid analgesics, opioids on an as needed basis and/or combination products, and chronic opioid therapy in a progressive plan of pain management such as outlined by the World Health Organization, the Agency for Healthcare Research and Quality, and the American Pain Society.

2.1 Individualization of Dosage

the total daily dose, potency and specific characteristics of the opioid the patient has been taking previously;
the reliability of the relative potency estimate used to calculate the equivalent oxycodone hydrochloride dose needed;
the patient's degree of opioid tolerance;
the general condition and medical status of the patient;
concurrent medications;
the type and severity of the patient's pain;
risk factors for abuse, addiction or diversion, including a prior history of abuse, addiction or diversion.

The following dosing recommendations, therefore, can only be considered suggested approaches to what is actually a series of clinical decisions over time in the management of the pain of each individual patient.

Continual re-evaluation of the patient receiving oxycodone hydrochloride is important, with special attention to the maintenance of pain control and the relative incidence of side effects associated with therapy. During chronic therapy, especially for non-cancer-related pain, periodically re-assess the continued need for the use of opioid analgesics.

During periods of changing analgesic requirements, including initial titration, frequent contact is recommended between physician, other members of the healthcare team, the patient, and the caregiver/family.

2.2 Initiation of Therapy in Opioid-Naive Patients

Oxycodone Hydrochloride Capsules: 5 to 15 mg every 4 to 6 hours as needed for pain.

Titrate the dose based upon the individual patient's response to their initial dose of oxycodone hydrochloride. Adjust the dose to an acceptable level of analgesia taking into account the improvement in pain intensity and the tolerability of the oxycodone by the patient.

2.3 Conversion to Oral Oxycodone Hydrochloride

Consider the following general points regarding opioid conversions.

Conversion From other Non-Oxycodone Opioids to Oral Oxycodone Hydrochloride.

In converting patients from other opioids to oxycodone hydrochloride, close observation and adjustment of dosage based upon the patient's response to oxycodone hydrochloride is imperative. Physicians and other healthcare professionals are advised to refer to published relative potency information, keeping in mind that conversion ratios are only approximate.

Conversion From Controlled-Release Oral Oxycodone to Oral Oxycodone Hydrochloride.

The relative bioavailability of Oxycodone Hydrochloride Capsule compared to controlled-release oxycodone is unknown. The extended duration of release of oxycodone hydrochloride from controlled-release tablets results in reduced maximum and increased minimum plasma oxycodone hydrochloride concentrations than with shorter acting oxycodone hydrochloride products. Conversion from controlled-release tablets could lead to excessive sedation at peak serum levels. Therefore, dose adjustment with close observation is necessary.

Conversion From Oral Oxycodone Hydrochloride to Controlled-Release Oral Oxycodone.

The relative bioavailability of Oxycodone Hydrochloride Capsules compared to controlled-release oxycodone is unknown, so conversion to controlled-release tablets must be accompanied by close observation for signs of excessive sedation.

2.4 Maintenance of Therapy

2.5 Cessation of Therapy

3 DOSAGE FORMS AND STRENGTHS

Each oxycodone hydrochloride capsule has an opaque yellow cap imprinted in black ink with "LV" and an opaque white body imprinted in black ink with "901" containing 5 mg of oxycodone hydrochloride, USP.

4 CONTRAINDICATIONS

Oxycodone hydrochloride is contraindicated in patients with respiratory depression in the absence of resuscitative equipment.

Oxycodone hydrochloride is contraindicated in any patient who has or is suspected of having paralytic ileus.

Oxycodone hydrochloride is contraindicated in patients with acute or severe bronchial asthma or hypercarbia.

Oxycodone hydrochloride is contraindicated in patients with known hypersensitivity to oxycodone, oxycodone salts, or any components of the product.

5 WARNINGS AND PRECAUTIONS

5.1 Respiratory Depression

Use oxycodone hydrochloride with extreme caution in patients with chronic obstructive pulmonary disease or cor pulmonale and in patients having a substantially decreased respiratory reserve (e.g., severe kyphoscoliosis), hypoxia, hypercapnia, or preexisting respiratory depression. In such patients, even usual therapeutic doses of oxycodone hydrochloride may increase airway resistance and decrease respiratory drive to the point of apnea. Consider alternative non-opioid analgesics, and use oxycodone hydrochloride only under careful medical supervision at the lowest effective dose in such patients.

5.2 Misuse, Abuse and Diversion of Opioids

Oxycodone hydrochloride can be abused in a manner similar to other opioid agonists, legal or illicit. This should be considered when prescribing or dispensing oxycodone hydrochloride in situations where the physician or pharmacist is concerned about an increased risk of misuse, abuse, or diversion.

Oxycodone hydrochloride may be abused by crushing, chewing, snorting or injecting the product. These practices pose a significant risk to the abuser that could result in overdose and death. [See DRUG ABUSE AND DEPENDENCE (9)]

Concerns about abuse, addiction, and diversion should not prevent the proper management of pain. 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.

5.3 Interactions with Alcohol and Drugs of Abuse

5.4 Use In Head Injury and Increased Intracranial Pressure

₂

5.5 Hypotensive Effect

Administer oxycodone hydrochloride with caution to patients in circulatory shock, as vasodilation produced by the drug may further reduce cardiac output and blood pressure.

5.6 Gastrointestinal Effects

The administration of oxycodone hydrochloride may obscure the diagnosis or clinical course in patients with acute abdominal condition.

5.7 Use In Pancreatic/Biliary Tract Disease

5.8 Special Risk Groups

(8.5)

Exercise caution in the administration of oxycodone hydrochloride to patients with CNS depression, toxic psychosis, acute alcoholism and delirium tremens. All opioids may aggravate convulsions in patients with convulsive disorders, and all opioids may induce or aggravate seizures in some clinical settings.

Keep Oxycodone Hydrochloride capsules out of the reach of children. In case of accidental ingestion, seek emergency medical help immediately.

5.9 Driving and Operating Machinery

(7)

5.10 Cytochrome P450 3A4 Inhibitors and Inducers

If co-administration is necessary, caution is advised when initiating oxycodone treatment in patients currently taking, or discontinuing, CYP3A4 inhibitors or inducers. Evaluate these patients at frequent intervals and consider dose adjustments until stable drug effects are achieved. [see Drug Interactions (7.4) and Clinical Pharmacology (12.3) ]

6 ADVERSE REACTIONS

Serious adverse reactions that may be associated with oxycodone therapy in clinical use are those observed with other opioid analgesics and include: respiratory depression, respiratory arrest, circulatory depression, cardiac arrest, hypotension, and/or shock.

The common adverse events seen on initiation of therapy with oxycodone are also typical opioid side effects. These events are dose dependent, and their frequency depends on the clinical setting, the patient's level of opioid tolerance, and host factors specific to the individual. They should be expected and managed as a part of opioid therapy. The most frequent of adverse events include nausea, constipation, vomiting, headache, and pruritus.

The frequency of adverse events during initiation of opioid therapy may be minimized by careful individualization of starting dosage, slow titration and the avoidance of large rapid swings in plasma concentration of the opioid. Many of these common adverse events may abate as therapy is continued and some degree of tolerance is developed, but others may be expected to remain throughout therapy.

In all patients for whom dosing information was available (n=191) from the open-label and double-blind studies involving immediate-release oxycodone, the following adverse events were recorded in oxycodone treated patients with an incidence greater than or equal to 3%. In descending order of frequency they were: nausea, constipation, vomiting, headache, pruritus, insomnia, dizziness, asthenia, and somnolence.

The following adverse experiences occurred in less than 3% of patients involved in clinical trials with oxycodone:

Body as a Whole:
abdominal pain, accidental injury, allergic reaction, back pain, chills and fever, fever, flu syndrome, infection, neck pain, pain, photosensitivity reaction, and sepsis.

Cardiovascular:
deep thrombophlebitis, heart failure, hemorrhage, hypotension, migraine, palpitation, and tachycardia.

Digestive:
anorexia, diarrhea, dyspepsia, dysphagia, gingivitis, glossitis, and nausea and vomiting.

Hemic and Lymphatic:
anemia and leukopenia.

Metabolic and Nutritional:
edema, gout, hyperglycemia, iron deficiency anemia and peripheral edema.

Musculoskeletal:
arthralgia, arthritis, bone pain, myalgia and pathological fracture.

Nervous:
agitation, anxiety, confusion, dry mouth, hypertonia, hypesthesia, nervousness, neuralgia, personality disorder, tremor, and vasodilation.

Respiratory:
bronchitis, cough increased, dyspnea, epistaxis, laryngismus, lung disorder, pharyngitis, rhinitis, and sinusitis.

Skin and Appendages:
herpes simplex, rash, sweating, and urticaria.

Special Senses:
amblyopia.

Urogenital:
urinary tract infection

7 DRUG INTERACTIONS

7.1 CNS Depressants

7.2 Muscle Relaxants

7.3 Mixed Agonist/Antagonist Opioid Analgesics

7.4 Agents Affecting Cytochrome P450 Enzymes

CYP3A4 Inhibitors
A published study showed that the co-administration with voriconazole, a CYP3A4 inhibitor, significantly increased the plasma concentrations of oxycodone. Inhibition of CYP3A4 activity by its inhibitors, such as macrolide antibiotics (e.g., erythromycin), azole-antifungal agents (e.g., ketoconazole), and protease inhibitors (e.g., ritonavir), may prolong opioid effects. If co-administration is necessary, caution is advised when initiating therapy with, currently taking, or discontinuing CYP3A4 inhibitors. Evaluate these patients at frequent intervals and consider dose adjustments until stable drug effects are achieved. [see Clinical Pharmacology (12.3) ]

CYP3A4 Inducers
A published study showed that the co-administration of rifampin, a drug metabolizing enzyme inducer, significantly decreased plasma oxycodone concentrations. Induction of CYP3A4 activity by its inducers, such as rifampin, carbamazepine, and phenytoin, may lead to a lack of efficacy or, possibly, development of an abstinence syndrome in a patient who had developed physical dependence to oxycodone. If co-administration is necessary, caution is advised when initiating therapy with, currently taking, or discontinuing CYP3A4 inducers. Evaluate these patients at frequent intervals and consider dose adjustments until stable drug effects are achieved. [see Clinical Pharmacology (12.3) ]

CYP2D6 Inhibitors
Oxycodone is metabolized in part to oxymorphone via the cytochrome p450 isoenzyme CYP2D6. While this pathway may be blocked by a variety of drugs (e.g., certain cardiovascular drugs and antidepressants), such blockade has not yet been shown to be of clinical significance with this agent. However, clinicians should be aware of this possible interaction.

7.5 Monoamine Oxidase Inhibitors (MAOIs)

No specific interaction between oxycodone and monoamine oxidase inhibitors has been observed, but caution in the use of any opioid in patients taking this class of drugs is appropriate.

7.6 Anticholinergics

Anticholinergics or other medications with anticholinergic activity when used concurrently with opioid analgesics may result in increased risk of urinary retention and/or severe constipation, which may lead to paralytic ileus.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category B:

Teratogenic effects
Reproduction studies in Sprague-Dawley rats and New Zealand rabbits revealed that when oxycodone was administered orally at doses up to 16 mg/kg (approximately 2 times the daily oral dose of 90 mg for adults on a mg/m₂ basis) and 25 mg/kg (approximately 5 times the daily oral dose of 90 mg on a mg/m² basis), respectively was not teratogenic or embryo-fetal toxic.

Nonteratogenic effects
Neonates whose mothers have taken oxycodone chronically may exhibit respiratory depression and/or withdrawal symptoms, either at birth and/or in the nursery.

8.3 Nursing Mothers

8.4 Pediatric Use

8.5 Geriatric Use

8.6 Hepatic Impairment

8.7 Renal Impairment

9 DRUG ABUSE AND DEPENDENCE

9.1 Controlled Substance

Oxycodone hydrochloride is a mu-agonist opioid and is a Schedule II controlled substance. Oxycodone hydrochloride, like other opioids used in analgesia, can be abused and is subject to criminal diversion.

9.2 Abuse

"Drug-seeking" behavior is very common in addicts and drug abusers. Drug seeking tactics include emergency calls or visits near the end of office hours, refusal to undergo appropriate examination, testing or referral, repeated "loss" of prescriptions, tampering with prescriptions and reluctance to provide prior medical records or contact information for other treating physician(s). "Doctor shopping" to obtain additional prescriptions is common among drug abusers and people suffering from untreated addiction.

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. The converse is also true. In addition, abuse of opioids can occur in the absence of true addiction and is characterized by misuse for nonmedical purposes, often in combination with other psychoactive substances. Careful record-keeping of prescribing information, including quantity, frequency, and renewal requests is strongly advised.

Oxycodone hydrochloride is intended for oral use only. Abuse of oxycodone hydrochloride poses a risk of overdose and death. The risk is increased with concurrent abuse of alcohol and other substances. Parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and HIV.

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

Infants born to mothers physically dependent on opioids will also be physically dependent and may exhibit respiratory difficulties and withdrawal symptoms. [See USE IN SPECIFIC POPULATIONS (8.2) ]

9.3 Dependence

The opioid abstinence or withdrawal syndrome is characterized by some or all of the following: restlessness, lacrimation, rhinorrhea, yawning, perspiration, chills, myalgia, and mydriasis. Other symptoms also may develop, including irritability, anxiety, backache, joint pain, weakness, abdominal cramps, insomnia, nausea, anorexia, vomiting, diarrhea, or increased blood pressure, respiratory rate, or heart rate.

In general, taper opioids rather than abruptly discontinue. [See DOSAGE AND ADMINISTRATION (2.5) ]

10 OVERDOSAGE

10.1 Symptoms

Oxycodone hydrochloride may cause 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). Marked mydriasis rather than miosis may be seen with hypoxia in overdose situations. [See CLINICAL PHARMACOLOGY (12) ]

10.2 Treatment

The pure opioid antagonists, naloxone or nalmefene, are specific antidotes to respiratory depression resulting from opioid overdose. Since the duration of reversal is expected to be less than the duration of action of oxycodone hydrochloride, carefully monitor the patient until spontaneous respiration is reliably re-established. If the response to opioid antagonists is suboptimal or only brief in nature, administer additional antagonist as directed by the manufacturer of the product.

Do not administer opioid antagonists in the absence of clinically significant respiratory or circulatory depression secondary to oxycodone overdose. Administer such agents cautiously to persons who are known, or suspected to be physically dependent on oxycodone. In such cases, an abrupt or complete reversal of opioid effects may precipitate an acute abstinence syndrome.

In an individual physically dependent on opioids, administration of the usual dose of the antagonist will precipitate an acute withdrawal syndrome. The severity of the withdrawal symptoms experienced will depend on the degree of physical dependence and the dose of the antagonist administered. Reserve use of an opioid antagonist for cases where such treatment is clearly needed. If it is necessary to treat serious respiratory depression in the physically dependent patient, initiate administration of the antagonist with care and titrate with smaller than usual doses.

11 DESCRIPTION

Oxycodone hydrochloride is a white, odorless crystalline powder derived from the opium alkaloid, thebaine. It is soluble in water and slightly soluble in alcohol.

Chemically, oxycodone hydrochloride is (5R,9R,13S,14S)-4, 5α-epoxy-14-hydroxy-3-methoxy-17-methylmorphinan-6-one, hydrochloride (salt) with a molecular mass of 351.82.

Each hard gelatin capsule contains 5 mg of oxycodone hydrochloride, USP and the following inactive ingredients: colloidal silicon dioxide, FD&C Yellow #6, gelatin, lactose anhydrous, magnesium stearate, microcrystalline cellulose, pregelatinized starch, sodium lauryl sulfate, sodium starch glycolate, titanium dioxide and yellow iron oxide.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Effects on the Central Nervous System (CNS)
The principal therapeutic action of oxycodone hydrochloride is analgesia. Although the precise mechanism of the analgesic action is unknown, specific CNS opioid receptors for endogenous compounds with oxycodone hydrochloride-like activity have been identified throughout the brain and spinal cord and are likely to play a role in the expression and perception of analgesic effects. In common with other opioids, oxycodone hydrochloride causes respiratory depression, in part by a direct effect on the brainstem respiratory centers. Oxycodone and related opioids depress the cough reflex by direct effect on the cough center in the medulla. Oxycodone causes miosis, even in total darkness.

Effects on the Gastrointestinal Tract And Other Smooth Muscle
Gastric, biliary and pancreatic secretions are decreased by Oxycodone hydrochloride. Oxycodone hydrochloride, like other opioid analgesics, produces some degree of nausea and vomiting which is caused by direct stimulation of the chemoreceptor trigger zone (CTZ) located in the medulla. The frequency and severity of emesis gradually diminishes with time. Oxycodone hydrochloride may cause a decrease in the secretion of hydrochloric acid in the stomach, may reduce motility, while increasing the tone in the antrum of the stomach and duodenum. Digestion of food in the small intestine is delayed and propulsive contractions are decreased. Propulsive peristaltic waves in the colon are decreased, while tone may be increased to the point of spasm. The end result may be constipation. Oxycodone hydrochloride may also cause spasm of the sphincter of Oddi and transient elevations in serum amylase.

Effects on the Cardiovascular System
In therapeutic doses, Oxycodone hydrochloride, produces peripheral vasodilatation (arteriolar and venous), decreased peripheral resistance, and inhibits baroreceptor reflexes. Manifestations of histamine release and/or peripheral vasodilatation may include pruritus, flushing, red eyes, sweating, and/or orthostatic hypotension. Caution should be used in hypovolemic patients, such as those suffering acute myocardial infarction, because oxycodone may cause or further aggravate their hypotension. Caution should also be used in patients with corpulmonale who have received therapeutic doses of opioids.

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.

Immune System
Opioids have been shown to have a variety of effects on components of the immune system in in-vitro and animal models. The clinical significance of these findings is unknown.

12.3 Pharmacokinetics

The oral bioavailability of oxycodone is 60% to 87%. Oxycodone is extensively metabolized and eliminated primarily in the urine as both conjugated and unconjugated parent and its metabolites. The apparent elimination half-life of oxycodone is approximately 4 hours.

Absorption
About 60 to 87% of an oral dose reaches the systemic circulation in comparison to a parenteral dose. This high oral bioavailability (compared to other opioids) is due to lower pre-systemic and/or first-pass metabolism of oxycodone.

Food Effects
When administered with a high-fat meal mean AUC values are increased by 23% and peak concentrations are decreased by 14%. Food caused a delay in T_max (1.00 to 3.00 hours).

Distribution
Following intravenous administration, the volume of distribution (Vss) for oxycodone was 2.6 L/kg. Plasma protein binding of oxycodone at 37°C and a pH of 7.4 was about 45%. Oxycodone has been found in breast milk.

Metabolism
Oxycodone hydrochloride is extensively metabolized by multiple metabolic pathways to noroxycodone, oxymorphone, and noroxymorphone, which are subsequently glucuronidated. CYP3A4 mediated N-demethylation to noroxycodone is the primary metabolic pathway of oxycodone with less contribution from CYP2D6 mediated O-demethylation to oxymorphone. Therefore, the formation of these and related metabolites can, in theory, be affected by other drugs. The major circulating metabolite is noroxycodone with an AUC ratio of 0.6 relative to that of oxycodone. Noroxycodone is reported to be a considerably weaker analgesic than oxycodone. Oxymorphone, although possessing analgesic activity, is present in the plasma only in low concentrations. The correlation between oxymorphone concentrations and opioid effects was much less than that seen with oxycodone plasma concentrations. The analgesic activity profile of other metabolites is not known.

Excretion
Oxycodone and its metabolites are excreted primarily via the kidney. The amounts measured in the urine have been reported as follows: free oxycodone up to 19%; conjugated oxycodone up to 50%; free oxymorphone 0%; conjugated oxymorphone <14%; both free and conjugated noroxycodone have been found in the urine but not quantified. The total plasma clearance was 0.8 L/min for adults.

Apparent elimination half-life of oxycodone following the administration of oxycodone is approximately 4 hours.

Special Populations

Elderly: Information obtained from oxycodone tablets indicate that the plasma concentrations of oxycodone did not appear to be increased in patients over the age of 65.

Gender: Information obtained from oxycodone tablets support the lack of gender effect on the pharmacokinetics of oxycodone.

Renal Impairment: Information obtained from oxycodone tablets indicate that patients with renal impairment (defined as creatinine clearance <60 mL/min) had higher plasma concentrations of oxycodone than subjects with normal renal function.

Hepatic Impairment: Since oxycodone is extensively metabolized, its clearance may decrease in patients with hepatic impairment.

Drug-Drug Interactions

CYP3A4 Inhibitors
CYP3A4 is the major enzyme involved in noroxycodone formation. A published study showed that the co-administration of voriconazole, a CYP3A4 inhibitor, increased oxycodone AUC and C_max by 3.6 and 1.7 fold, respectively.

CYP3A4 Inducers
A published study showed that the co-administration of rifampin, a drug metabolizing enzyme inducer, decreased oxycodone AUC and C_max values by 86% and 63%, respectively.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis
Studies of oxycodone hydrochloride to evaluate its carcinogenic potential have not been conducted.

Mutagenesis
Oxycodone hydrochloride was genotoxic in an in vitro mouse lymphoma assay in the presence of metabolic activation. There was no evidence of genotoxic potential in an in vitro bacterial reverse mutation assay (Salmonella typhimurium and Escherichia coli) and in an assay for chromosomal aberrations (in vivo mouse bone marrow micronucleus assay).

Impairment of Fertility
The potential effects of oxycodone on male and female fertility have not been evaluated.

17 PATIENT COUNSELING INFORMATION

Provide the following information to patients receiving oxycodone hydrochloride or their caregivers:

Advise patients that oxycodone hydrochloride is a narcotic pain reliever, and should be taken only as directed.
Advise patients that oxycodone hydrochloride capsule is available in one strength: 5 mg.
Advise patients not to adjust the dose of oxycodone hydrochloride without consulting with a physician or other healthcare professional.
Advise patients that oxycodone hydrochloride may cause drowsiness, dizziness, or lightheadedness and may impair mental and/or physical ability required for the performance of potentially hazardous tasks (e.g., driving, operating machinery). Advise patients started on oxycodone hydrochloride or patients whose dose has been adjusted to refrain from any potentially dangerous activity until it is established that they are not adversely affected.
Advise patients that oxycodone hydrochloride will add to the effect of alcohol and other CNS depressants (such as antihistamines, sedatives, hypnotics, tranquilizers, general anesthetics, phenothiazines, other opioids, and monoamine oxidase [MAO] inhibitors).
Instruct patients not to combine oxycodone hydrochloride with central nervous system depressants (sleep aids, tranquilizers) except by the orders of the prescribing physician, and not to combine with alcohol because dangerous additive effects may occur, resulting in serious injury or death.
Instruct women of childbearing potential who become or are planning to become pregnant to consult a physician prior to initiating or continuing therapy with oxycodone hydrochloride.
Advise patients that safe use in pregnancy has not been established and that prolonged use of opioid analgesics during pregnancy may cause fetal-neonatal physical dependence, and neonatal withdrawal may occur.
If patients have been receiving treatment with oxycodone hydrochloride for more than a few weeks and cessation of therapy is indicated, counsel them on the importance of safely tapering the dose and that abruptly discontinuing the medication could precipitate withdrawal symptoms. Provide a dose schedule to accomplish a gradual discontinuation of the medication.
Advise patients that sharing this oxycodone can result in fatal overdose and death.
Advise patients that oxycodone hydrochloride is a potential drug of abuse. They must protect it from theft. It should never be given to anyone other than the individual for whom it was prescribed.
Instruct patients to keep oxycodone hydrochloride in a secure place out of the reach of children. When oxycodone hydrochloride is no longer needed, the unused capsules should be destroyed by flushing down the toilet.
Advise patients taking oxycodone hydrochloride of the potential for severe constipation; appropriate laxatives and/or stool softeners as well as other appropriate treatments should be initiated from the onset of opioid therapy.
Advise patients of the most common adverse events that may occur while taking oxycodone hydrochloride: constipation, nausea, somnolence, lightheadedness, dizziness, sedation, vomiting, and sweating.
Advise patients to call 911 or the local Poison Control center, and get emergency help immediately if they take more oxycodone than prescribed, or overdose.
Advise patients, that if they miss a dose, to take the missed dose as soon as possible. If it is almost time for the next dose, skip the missed dose and go back to their regular dosing schedule. Do not take two doses at once unless instructed by their doctor.
