Each gram of sulfacetamide sodium 10% and sulfur 5% contains 100 mg of Sodium Sulfacetamide USP and 50 mg of Sulfur USP in a cream containing: Benzyl Alcohol, Emulsifying Wax, Hamaelis virginiana (Witch Hazel) Distillate, Kaolin, Propanediol, Propylene Glycol, Purified Water, Quillaja (Quillaia) saponaria Extract, Silicon Dioxide, and Sodium Thiosulfate.

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, sulfacetamide sodium 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.

Sulfacetamide sodium and sulfur cleanser is indicated in the topical control of acne vulgaris, acne rosacea and seborrheic dermatitis.

Sulfacetamide sodium and sulfur cleanser is contraindicated for use by patients having known hypersensitivity to sulfonamides, sulfur or any other component of this preparation. Sulfacetamide sodium and sulfur cleanser is not to be used by patients with kidney disease.

Although rare, sensitivity to sulfacetamide sodium may occur. Therefore, caution and careful supervision should be observed when prescribing this drug for patients who may be prone to hypersensitivity to topical sulfonamides. Systemic toxic reactions such as agranulocytosis, acute hemolytic anemia, purpura hemorrhagica, drug fever, jaundice, and contact dermatitis indicate hypersensitivity to sulfonamides. Particular caution should be employed if areas of denuded or abraded skin are involved.

FOR EXTERNAL USE ONLY. Keep away from eyes. Keep out of reach of children. Keep container tightly closed.

General — lf 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 sulfacetamide sodium 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 — Longterm studies in animals have not been performed to evaluate carcinogenic potential.

Pregnancy: Category C — Animal reproduction studies have not been conducted with sulfacetamide sodium and sulfur lotion. It is also not known whether sulfacetamide sodium and sulfur cleanser can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Sulfacetamide sodium and sulfur cleanser should be given to a pregnant woman only if clearly needed.

Nursing Mothers — It is not known whether sulfacetamide sodium is excreted in the human milk following topical use of sulfacetamide sodium and sulfur lotion. 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 sulfacetamide sodium and sulfur cleanser is administered to a nursing woman.

Pediatric Use — Safety and effectiveness in children under the age of 12 have not been established.

Although rare, sulfacetamide sodium may cause local irritation.

Apply once or twice daily to affected areas or as directed by your physician. Wet skin and liberally apply to areas to be cleansed. Massage gently into skin for 10-20 seconds, working into lather. RInse thoroughly and pat dry. If drying occurs, it may be controlled by rinsing off product sooner or using less often.
