Miconazole, sold under the brand name Monistat among others, is an antifungal medication used to treat ring worm, pityriasis versicolor, and yeast infections of the skin or vagina.[2] It is used for ring worm of the body, groin (jock itch), and feet (athlete's foot).[2] It is applied to the skin or vagina as a cream or ointment.[2][3]

Common side effects include itchiness or irritation of the area in which it was applied.[2] Use in pregnancy is believed to be safe for the baby.[4] Miconazole is in the imidazole family of medications.[2] It works by decreasing the ability of fungi to make ergosterol, an important part of their cell membrane.[2]

Miconazole was patented in 1968 and approved for medical use in 1971.[5] It is on the World Health Organization's List of Essential Medicines.[6] It is available as a generic medication.[2]
