      "clinical_pharmacology": [
        "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 known, but it has been reported that it inhibits the growth of Propionibacterium acnes and the formation of free fatty acids."

      "precautions": [
        "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 longterm 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 Sodium Sulfacetamide 10% and Sulfer 1% Emulsion. It is not known whether Sodium Sulfacetamide 10% and Sulfer 1% Emulsion can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Sodium Silfacetamide 10% and Sulfer 1% Emulsion should be given to a pregnant woman only if clearly needed. NURSING MOTHERS It is not known whether sodium sulfacetamide is excreted in the human milk following topical use of Sodium Sulfacetamide 10% and Sulfur 1% Emulsion. However, small amounts of orally administered sulfonamides have been reported to be eliminated in human milk. In view of this and because many drugs are excreted in human milk, caution should be exercised when Sodium Sulfacetamide 10% and Sulfur 1% Emulsion is administered to a nursing woman. PEDIATRIC USE Safety and effectiveness in children under the age of 12 have not been established."
