Sulfo-Lo (Topical)

Sulfur is used to treat various skin problems. Sulfur cream, lotion, ointment, and bar soap are used for acne. Sulfur ointment is used for seborrheic dermatitis and scabies. Sulfur might also be used for other conditions as your doctor decides.

Some of these products are available only with a prescription from your doctor.

When using sulfur, do not use any of the following products on the same affected area as this medicine, unless your doctor tells you to:

• Abrasive soaps or cleansers
• Alcohol-containing products
• Any other topical acne treatment or product with a peeling agent (for example, benzoyl peroxide, resorcinol, salicylic acid, or tretinoin [vitamin A acid])
• Cosmetics or soaps that dry the skin
• Medicated cosmetics
• Other topical skin medicine

Using any of these products on the same affected area as sulfur may cause serious skin irritation.

Do not use any topical mercury-containing product, like ammoniated mercury ointment, on the same area as this medicine. Doing so may cause a bad smell, may irritate the skin, and may stain the skin black. If you have any questions about this, ask your health care professional.
