Know the basics

What is clotrimazole used for?

Clotrimazole is used to treat skin infections such as athlete’s foot, jock itch, ringworm, and other fungal skin infections (candidiasis). Clotrimazole is also used to treat a skin condition known as pityriasis (tinea versicolor), a fungal infection that causes a lightening or darkening of the skin of the neck, chest, arms, or legs. Clotrimazole is an azole antifungal that works by preventing the growth of fungus.

How should I take clotrimazole?

Use clotrimazole on the skin only. Clean and thoroughly dry the area to be treated. Apply this medication to the affected skin, usually twice a day or as directed by your doctor. Dosage and length of treatment depends on the type of infection being treated. Do not apply this more often than prescribed. Your condition will not clear faster, but side effects may be increased.

Apply enough medication to cover the affected area and some of the surrounding skin. After applying clotrimazole , wash your hands. Do not wrap, cover or bandage the area unless directed to do so by your doctor.

Do not apply clotrimazole in the eyes, nose, mouth, or vagina.

Use clotrimazole regularly in order to get the most benefit from it. Remember to use it at the same time(s) each day.

Continue to use clotrimazole until the full prescribed amount is finished, even if symptoms disappear after starting clotrimazole. Stopping clotrimazole too early may allow the fungus to continue to grow, which may result in a relapse of the infection.

Inform your doctor if your condition persists after 4 weeks of treatment or worsens at any time.

How do I store clotrimazole?

Clotrimazole is best stored at room temperature away from direct light and moisture. To prevent drug damage, you should not store clotrimazole in the bathroom or the freezer. There may be different brands of clotrimazole that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist.
