FULL PRESCRIBING INFORMATION
DESCRIPTION: Sodium sulfacetamide is a sulfonamide with antibacterial activity. Sulfur acts as a keratolytic agent. Chemically, sodium sulfacetamide is N-[(4-aminophenyl)sulfonyl]-acetamide, monosodium salt, monohydrate. The structural formula is:
Each mL of 10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle) contains 100 mg of sodium sulfacetamide and 50 mg of sulfur in an emulsion base containing 10% Urea, propylene glycol, isopropyl myristate, mineral oil, polysorbate 60, sorbitan monostearate, cetyl alcohol, cocoglycerides, stearyl alcohol, benzyl alcohol, glyceryl stearate and PEG 100 stearate, dimethicone, fragrance, disodium EDTA, xanthan gum, zinc pyrithione, sodium thiosulfate, purified water, magnesium aluminum silicate, and methyl paraben.
CLINICAL PHARMACOLOGY: The most widely accepted mechanism of action of sulfonamides is the Woods-Fildes theory, which is based on the fact that sulfonamides act as competitive antagonists to para-aminobenzoic acid (PABA), an essential component for bacterial growth. While absorption through intact skin has not been determined, sodium sulfacetamide is readily absorbed from the gastrointestinal tract when taken orally and excreted in the urine, largely unchanged. The biological half-life has variously been reported as 7 to 12.8 hours. The exact mode of action of sulfur in the treatment of acne is unknown, but it has been reported that it inhibits the growth of Propionibacterium acnes and the formation of free fatty acids.
Uses

Therefore, caution and careful supervision should be observed when prescribing this drug tor patients who may be prone to hypersensitivity to topical sulfonamides.

PRECAUTIONS: General - If irritation develops, use of the product should be discontinued and appropriate therapy instituted. Patients should be carefully observed for possible local irritation or sensitization during long-term therapy. The object of this therapy is to achieve desquamation without irritation, but sodium sulfacetamide and sulfur can cause reddening and scaling of the epidermis. These side effects are not unusual in the treatment of acne vulgaris, but patients should be cautioned about the possibility.
Information for Patients - Avoid contact with eyes, eyelids, lips and mucous membranes. If accidental contact occurs, rinse with water. If excessive irritation develops, discontinue use and consult your physician.
Carcinogenesis, Mutagenesis and Impairment of Fertility - Long-term studies in animals have not been performed to evaluate carcinogenic potential.
Pregnancy - Category C. Animal reproduction studies have not been conducted with 10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle). It is also not known whether 10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle) can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. 10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle) should be given to a pregnant woman only if clearly needed.
Nursing Mothers - It is not known whether sodium sulfacetamide is excreted in human milk following topical use of 10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle). However, small amounts of orally administered sulfonamides have been reported to be excreted in human milk. For this reason, and because many drugs are excreted in human milk, caution should be exercised when 10% Sodium Sulfacetamide 5% Sulfur Aqueous Gel (in a Urea vehicle) is administered to a nursing woman.
