How does this medication work? What will it do for me?
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 causes 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.
This medication may be available under multiple brand names and/or in several different forms.

How should I use this medication?
To treat diaper rash for children, apply a thin layer and gently massage enough cream onto the affected and surrounding skin area twice daily at a diaper change, in the morning and evening. If symptoms worsen or if there is no improvement after 2 weeks, contact your doctor. Do not use for longer than 14 days.
To treat jock itch, athlete's foot, and ringworm for adults, apply a thin layer of cream and gently massage it into the affected and surrounding skin area twice daily, in the morning and evening. Improvement in the itching should be seen within the first week. For jock itch and ringworm, treatment should be continued for 2 to 4 weeks. For athlete's foot, treatment may be needed for at least 4 weeks.
For foot infections, make sure you dry your feet thoroughly (especially between the toes) and wear well-fitted, ventilated shoes and cotton or wool socks to improve treatment results and prevent repeat infections. Treatment with clotrimazole topical cream should continue for about 2 weeks after your symptoms have disappeared. This will help to prevent relapses.
