Topical clotrimazole is used to treat tinea corporis (ringworm; fungal skin infection that causes a red scaly rash on different parts of the body), tinea cruris (jock itch; fungal infection of the skin in the groin or buttocks), and tinea pedis (athlete’s foot; fungal infection of the skin on the feet and between the toes). Clotrimazole is in a class of antifungal medications called imidazoles. It works by stopping the growth of fungi that cause infection.

Dosage Of Clotrimazole Topical
Topical clotrimazole comes as a cream and liquid to apply to the skin. It is usually applied twice a day (morning and night). Follow the directions on the package label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use clotrimazole exactly as directed. Do not use more or less of it or use it more often than directed on the package or as directed by your doctor.
Topical clotrimazole is only for use on the skin. Do not let clotrimazole get into your eyes and do not swallow the medication. Clotrimazole does not work on the scalp or nails.
If you are using clotrimazole to treat jock itch, your symptoms should improve over 2 weeks of treatment. If you are using clotrimazole to treat athlete’s foot or ringworm, your symptoms should improve over 4 weeks of treatment. Call your doctor if your symptoms do not improve during this time or if your symptoms get worse at any time during your treatment.
To use topical clotrimazole, wash the affected area and dry thoroughly. Then apply a small amount of cream or liquid to cover the affected area of skin with a thin layer.
If you are treating an athlete’s foot, pay special attention to the spaces between the toes when applying clotrimazole. Also, be sure to wear well-fitting shoes that allow for air circulation, and change shoes and socks at least once a day.
If you are using the liquid, do not apply it to any severely cracked or irritated areas.
Keep all appointments with your doctor.
Ask your pharmacist any questions you have about clotrimazole.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
