Clotrimazole belongs to the class of medications called antifungals. It is used to treat various skin infections caused by fungus or yeast. Clotrimazole works by killing the overgrowth of yeast or fungus that is causing the infection.
Clotrimazole can be used to treat tinea pedis (athlete's foot), tinea cruris (jock itch), tinea corporis (ringworm), candidiasis (various yeast infections of the skin and mucous membranes), infected diaper rash, and tinea versicolor (patches of skin that are a different colour than the rest of the skin).
Clotrimazole usually starts to work within a few days of starting treatment. Treatment may be needed for up to 4 weeks, depending on the infection being treated.
