This medication is used to treat several skin problems (acne, acne rosacea, seborrheic dermatitis). Sodium sulfacetamide works by stopping the growth of certain bacteria on the skin that can lead to acne and worsen these other skin conditions. It belongs to a class of drugs known as sulfa antibiotics. Sulfur works by helping remove the top layer of dead skin. It belongs to a class of drugs known as keratolytics. It may also help kill acne-causing bacteria and unclog pores.

This medication may also contain other ingredients (for example, other keratolytics such as urea).

This medication is for use on the skin only.

Clean and dry the affected skin area and your hands. Some products need to be shaken before use. If so directed on the product label, shake the container well before each use. Apply a thin layer of the product to the areas of skin with acne, rosacea, or seborrhea as directed by your doctor, usually 1 to 3 times daily. Dosage is based on your medical condition and response to treatment. Follow your doctor's directions. Wash your hands with soap and water after each use.

Do not apply this product to skin that is cracked, broken, or raw because this may increase your risk of side effects.

Avoid getting this medication on your eyelids or lips, or in your eyes, nose, or mouth. If you do get medication in these areas, rinse with plenty of water.

Use this medication regularly to get the most benefit from it. Do not apply large amounts of this medication, use it more often, or use it for longer than prescribed. Your condition will not improve any faster, and your risk of side effects may increase.

Tell your doctor if your condition does not get better after a few weeks or if it worsens.

Mild peeling of the top layer of skin is expected. Skin irritation, redness, and scaling may also occur. If any of these effects last or get worse, stop using this medication and tell your doctor or pharmacist promptly.
