Proper use of Clotrim Antifungal

Apply enough clotrimazole to cover the affected and surrounding skin areas, and rub in gently.

Keep this medicine away from the eyes.

When clotrimazole is used to treat certain types of fungus infections of the skin, an occlusive dressing (airtight covering, such as kitchen plastic wrap) should not be applied over the medicine. To do so may cause irritation of the skin. Do not apply an occlusive dressing over this medicine unless you have been directed to do so by your doctor.

To help clear up your infection completely, it is very important that you keep using this medicine for the full time of treatment, even if your symptoms begin to clear up after a few days. Since fungus infections may be very slow to clear up, you may have to continue using this medicine every day for several weeks or more. If you stop using this medicine too soon, your symptoms may return. Do not miss any doses.
