What is nystatin 100 ointment used for?

Nystatin 100,000IU ointment is a topical antifungal used to treat skin infections caused by Candida yeast, such as cutaneous candidiasis, candidal diaper rash, and yeast infections in skin folds. It is applied directly to the affected skin and works only against Candida, not bacterial or ringworm infections.

Do I need a prescription for nystatin 100,000IU ointment?

Yes, nystatin ointment requires a valid prescription in the United States. A licensed healthcare provider must review your health information and confirm the medication is appropriate before it can be dispensed.

How does ordering and shipping work?

After you complete a brief health questionnaire, a licensed provider reviews your information and, if appropriate, issues a prescription. Your medication is then filled and shipped from a licensed U.S. pharmacy directly to your address.

How long does nystatin ointment take to work?

Many people notice improvement within a few days of consistent twice-daily use, though full healing can take longer. Continue applying the ointment for the full duration your prescriber recommends, and contact your provider if symptoms do not improve.

Is nystatin ointment the same as Mycostatin?

Yes, Mycostatin is a brand name for nystatin. Generic nystatin 100,000 units per gram ointment contains the same active ingredient and works the same way as the brand-name product.

Can nystatin ointment be used for diaper rash?

Nystatin ointment is FDA-approved for candidal diaper rash, meaning diaper rash caused by yeast. A provider should confirm the rash is caused by Candida before treatment, since ordinary diaper rash may not require an antifungal.

Can I use nystatin ointment for athlete's foot or ringworm?

No, nystatin is not effective against dermatophyte fungi, which cause athlete's foot and ringworm. It only treats Candida yeast infections, so a different antifungal would be needed for those conditions.

What Is Nystatin 100,000IU Ointment?

Nystatin 100,000 units per gram ointment is a topical antifungal medication in the polyene class, also sold under the brand name Mycostatin. It works by binding to the fungal cell membrane, causing the cell contents to leak out, which stops the growth of Candida yeast. It is applied directly to the skin and is not absorbed into the bloodstream in significant amounts. Nystatin ointment treats yeast infections of the skin only; it is not effective against bacterial or viral infections.
