Prescription Topical Antifungals for Athlete's Foot
Other topical antifungals
Topical medicines are put directly on the skin. These medicines are available in cream, solution, gel, and lotion forms. One medicine may be available in many forms. Your doctor will help you decide which form is best for you.
Lotrisone combines a topical antifungal (clotrimazole) with a topical corticosteroid (betamethasone).
Allylamines and azoles are different classes of antifungal medicine. Medicine from one class may work better for you than medicine from the other.
How It Works
All of these medicines kill fungi. See the medicine label for specific instructions. In general:
If you stop taking the medicines early, even after symptoms are gone, an athlete's foot infection will likely return. It is very important to use the medicine for the entire time directed.
Why It Is Used
Prescription antifungals usually are used to treat athlete's foot when treatment with nonprescription antifungals has not been successful or the athlete's foot is severe.
The topical forms are used for mild to moderate cases of athlete's foot.
Ciclopirox and sulconazole also can treat bacterial infections that might occur along with a fungal infection.
Ketoconazole penetrates thick skin well and is a good treatment option for moccasin-type infections.
Clotrimazole-betamethasone may be used when the athlete's foot rash is itchy and burning.
For severe cases or when topical medicines do not work, oral antifungal medicines (pills) are used.
How Well It Works
Both topical and oral forms of prescription antifungals are effective in curing athlete's foot for most people.
Topical allylamines require a shorter course of treatment (1 week) than do topical azoles (4 to 8 weeks). Also, studies show that allylamine medicines work slightly better than azole medicines.1 Although allylamines are more expensive than azoles, you use less of this medicine to successfully treat a fungal infection.
All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.

What To Think About
Topical antifungals rarely cause side effects. If you have a problem, stop using the medicine and talk to your doctor.
Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
Advice for women
If you are pregnant, breast-feeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
