In the U.S.—

In Canada—

• Antifungal, topical

Clotrimazole (kloe-TRIM-a-zole) topical preparations are used to treat fungus infections.

Some of these preparations are available only with your doctor's prescription. Others are available without a prescription; however, your doctor may have special instructions on the proper dose for your medical condition.

Clotrimazole is available in the following dosage forms:

Topical
• Cream (U.S. and Canada)
• Lotion (U.S.)
• Solution (U.S. and Canada)

If you are using this medicine without a prescription, carefully read and follow any precautions on the label. For topical clotrimazole, the following should be considered:

Allergies—Tell your doctor if you have ever had any unusual or allergic reaction to clotrimazole. Also tell your health care professional if you are allergic to any other substances, such as preservatives or dyes.

Pregnancy—Clotrimazole has not been studied in pregnant women during the first trimester (3 months). However, clotrimazole used vaginally during the second and third trimesters has not been shown to cause birth defects or other problems in humans.

Breast-feeding—It is not known whether topical clotrimazole passes into the breast milk. Although most medicines pass into breast milk in small amounts, many of them may be used safely while breast-feeding. Mothers who are using this medicine and who wish to breast-feed should discuss this with their doctor.

Children—This medicine has been tested in children and, in effective doses, has not been shown to cause different side effects or problems than it does in adults.

Older adults—Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults. Although there is no specific information comparing use of topical clotrimazole in the elderly with use in other age groups, this medicine is not expected to cause different side effects or problems in older people than it does in younger adults.

Other medicines—Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions may be necessary. Tell your health care professional if you are using any other topical prescription or nonprescription (over-the-counter [OTC]) medicine that is to be applied to the same area of the skin.

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 .

Dosing—

The dose of topical clotrimazole will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of topical clotrimazole. If your dose is different, do not change it unless your doctor tells you to do so:

The number of doses you use each day, the time allowed between doses, and the length of time you use the medicine depend on the medical problem for which you are using clotrimazole.
