Sulfacetamide (sul fa SEE ta mide) is a generic medication prescribed for certain skin conditions and specific types of eye infections. Sulfacetamide belongs to a group of drugs called sulfonamide antibiotics.

Doctors may prescribe sulfacetamide to treat:

• conjunctivitis (inflammation of the lining of the eye) or other eye infections caused by certain types of bacteria
• trachoma (infection of the eye caused by a type of bacteria called Chlamydia trachomatis), along with other antibiotics
• acne
• seborrheic dermatitis* (a condition that causes patches of oily, flaky skin)
• dandruff*
• certain skin infections caused by specific bacteria*

These uses differ based on the form of sulfacetamide your doctor prescribes.

* Note: The Food and Drug Administration (FDA) has not approved certain forms and uses of sulfacetamide. This is because certain forms of sulfacetamide (the shampoo and the liquid cleanser) have been available since before the FDA began its drug approval process. If you have questions about this, talk with your doctor or pharmacist.

Common questions about sulfacetamide

Below you’ll find answers to a few commonly asked questions about sulfacetamide.

What brand names are available for sulfacetamide?

Sulfacetamide is a generic drug. A generic medication contains an identical copy of the active drug in a brand-name medication. (An active drug is the ingredient that makes a medication work.) Generic drugs are believed to be as effective and safe as brand-name drugs. And generic drugs typically cost less compared to brand-name drugs.

Currently, certain forms of sulfacetamide are available as brand-name drugs, including:

• Bleph-10 eye drops
• Klaron topical lotion
• Ovace Plus topical lotion
• Ovace Plus shampoo
• Ovace Plus cleanser

Talk with your doctor or pharmacist to learn more about generic or brand-name drugs.

Is sulfacetamide safe for older adults?

Yes, sulfacetamide can be used in older adults (ages 65 years and older). Its safety is expected to be the same in older adults as in younger adults.

Regardless of age, some people may need a caregiver’s help to apply certain forms of sulfacetamide. For instance, if an individual has trouble keeping their hand steady, they may need help to apply sulfacetamide eye drops or sulfacetamide eye ointment. This is because it’s important not to touch the eye with the tip of the dropper or tube. Doing so could lead to injury or further infection.

Talk with your doctor or pharmacist if you have questions about using or applying sulfacetamide.

How does sulfacetamide work? And how long does it take to start working?

Sulfacetamide is an antibiotic. It works by preventing bacteria from making folic acid. Bacteria need folic acid to grow. By preventing bacteria from making folic acid, sulfacetamide stops the bacteria from growing.

Sulfacetamide begins working soon after the first application. But it may take a few days to weeks before your symptoms start to go away. How long it takes to clear can depend on the type of condition you have and when you start treatment. Talk with your doctor or pharmacist about how soon you might expect to see an improvement while using sulfacetamide.

What to ask your doctor

Let your doctor know if you have questions about sulfacetamide or would like more details about it.

Here’s a list of some possible questions you may want to ask your doctor:

• Am I at a higher risk for side effects of sulfacetamide than others?
• I’m allergic to sulfa antibiotics. Is it safe for me to use this product?
• My symptoms have gone away, but I still have some sulfacetamide left. Should I stop or keep using it until I finish it?
