Sulfatol Gel 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 Sulfatol™ Gel (Sodium Sulfacetamide 10%, and Sulfur 5% in a Urea vehicle) contains 100 mg of Sodium Sulfacetamide and 50 mg of Sulfur in an emulsion base containing Urea 10%, Benzyl Alcohol, Cetyl Alcohol, Cocoglycerides, Dimethicone, Disodium EDTA, Fragrance, Glyceryl and PEG-100 Stearate, Isopropyl Myristate, Light Mineral Oil, Polysorbate 60, Propylene Glycol, Sodium Thiosulfate, Sorbitan Monostearate, Stearyl Alcohol, Purified Water, Xanthan Gum, and Zinc Ricinoleate.

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.


Sulfatol™ Gel is indicated in the topical control of acne vulgaris, acne rosacea and seborrheic dermatitis.


Sulfatol™ Gel is contraindicated for use by patients having known hypersensitivity to sulfonamides, sulfur or any other component of this preparation. Sulfatol™ Gel is not to be used by patients with kidney disease.


Although rare, sensitivity to sodium sulfacetamide 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 tube tightly closed.



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.


Category C

Animal reproduction studies have not been conducted with Sulfatol™ Gel. It also is not known whether Sulfatol™ Gel can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Sulfatol™ Gel 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 Sulfatol™ Gel. 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 Sulfatol™ Gel is administered to a nursing woman.

Pediatric Use

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

Adverse Reactions

Although rare, sodium sulfacetamide may cause local irritation.
