Tioconazole is an antifungal medication used to treat infections caused by fungi or yeast. It works by stopping the growth of the fungus. Tioconazole is commonly available as a topical cream or vaginal ointment, primarily used to treat conditions like vaginal yeast infections, athlete’s foot, jock itch, and ringworm. It's known for its broad-spectrum antifungal activity and is often effective with a single-dose treatment when used for vaginal infections.
