Clotrimazole

What is clotrimazole?

Clotrimazole is an antifungal medication. It is like an antibiotic but is used to treat yeast (fungal) infections.

Oral clotrimazole is used to treat and prevent yeast infections of the mouth and throat.

Clotrimazole may also be used for purposes other than those listed in this medication guide.

Important Information

Take all of the clotrimazole that has been prescribed for you even if you begin to feel better. Your symptoms may begin to improve before the infection is completely treated.

Store clotrimazole at room temperature away from moisture and heat.
