Miconazole is an antifungal that has different uses in over-the-counter (OTC) medicines. It may be written as miconazole or miconazole nitrate, but it is the same active ingredient. Depending on the dose and form, miconazole can be used to treat symptoms associated with skin fungus infections such as athlete’s foot, jock itch, and ringworm. Miconazole can also be used to treat vaginal yeast infections. Miconazole is available in single-ingredient topical skin fungus medicines and in single-ingredient vaginal yeast infection products.
Miconazole is approved by the U.S. Food and Drug Administration (FDA) and is safe and effective when used according to label directions. While miconazole is available in medicines that treat skin fungus infections as well as in medicines that cure vaginal yeast infections, you should only use a miconazole-containing product that is labeled to treat the symptoms you are experiencing.
