Nystatin is a commonly prescribed antifungal medication used to treat fungal or yeast infections. It is available as oral tablets, oral suspension (liquid), topical cream, topical powder, and topical ointment. Nystatin exhibits its action by killing the infection-causing fungus. Do not take this drug if you have a previous history of allergy or hypersensitivity to Nystatin or any other components of the medication. In case of skin rash or yellowing of skin or white eyes, report to the doctor immediately.
Nystatin belongs to the class of drugs called polyenes. The drugs of this class kill the infection-causing fungus by forming pores in their cell membrane. The other medications in the polyene class include Amphotericin B, Trichomycin, Candicidin, and Pimaricin.
What Is Nystatin Used For?
Nystatin is widely used to treat and prevent fungal or yeast infections caused by the Candida species of fungus. It includes
Candidal vulvovaginitis (infection in the vagina or vulva caused by Candida fungus)
Candidiasis of the skin (skin infection caused by Candida fungus).
Gastrointestinal candidiasis (infections in the stomach or intestine caused by Candida fungus).
Oropharyngeal candidiasis (infection in the mouth or throat caused by Candida fungus)
How Does Nystatin Work?
Nystatin works by binding to a sterol called ergosterol present in the sensitive fungus's cell membrane. This binding will induce the membrane to form pores or channels, which will lead to the leaking of the cell components, which are crucial for the survival of the fungus. Thus, it will ultimately lead to the death of the fungus.
Onset of Action:
Nystatin is not absorbed (reaches the blood circulation) when taken orally or applied topically. It is eliminated through feces in its unchanged form. The onset of action of Nystatin is 24 to 72 hours.
There are no reported habit-forming tendencies reported in individuals taking Nystatin.
Avoid taking this medicine after it expires. The expiry date will be provided on the back of the packet.
