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. This is important because medicine from one class may work better 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). But 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.
Topical antifungals rarely cause side effects. Stop using the medicine if it results in severe blistering, itching, redness, dryness, or irritation.
See Drug Reference for a full list of side effects. (Drug Reference is not available in all systems.)
