What is Nystatin and How to Take It

Nystatin is an antifungal drug used to treat various fungi infections, mainly brought on by organisms resembling yeast, including the Candida species. It is a member of the polyene drug class and functions by attaching to ergosterol, an essential element of fungal cell membranes, making them porous and leaky. As a result, the fungal cells are eliminated, which causes the infection to clear up. Nystatin is frequently recommended for vaginal yeast infections, oral thrush, and superficial skin infections. It comes in many forms, including creams, ointments, oral tablets, and suspensions. Nystatin is typically viewed as safe and is regularly administered for babies and those with compromised immune systems who are more susceptible to fungal infections.

Nystatin over the counters is not available. Nystatin is a commonly prescribed antifungal medication available in various forms, including oral tablets, vaginal applications, and topical creams/ointments. For vaginal yeast infections, it is inserted once or twice daily for two weeks. It can be taken orally as tablets, lozenges, or liquid suspension, usually three to five times a day for fourteen days. Topical nystatin is applied twice daily to the affected skin. It’s essential to follow the prescribed dosage and complete the entire course of treatment to avoid recurrence. Only stop or adjust the dosage with your doctor’s guidance. Complying with instructions ensures effective management of fungal infections.

  • Stomach cramps, diarrhea, vomiting, and nausea are typical side effects. It’s possible to experience allergic responses, including a rash, itching, swelling, or breathing problems. Immediately notify your healthcare provider if such reactions occur.
