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 health professional 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 classes of antifungal medicine. This is important because there may be differences in how effective the classes are.

How It Works

---

All of these medicines kill fungi. See the medicine label for specific instructions. In general:

• Butenafine is used for 1 to 2 weeks.
• Other topical medicines are used for 4 weeks, except for topical ketoconazole, which is used for 6 weeks.

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.

Miconazole, ciclopirox, and sulconazole also fight bacterial infections.

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 for most people in curing athlete's foot.

Topical allylamines require a shorter course of treatment (1 week) than do topical azoles (4 to 8 weeks). Both types of medicine produce similar cure rates.¹ Although allylamines are more expensive than azoles, you use less of these medicines to successfully treat a fungal infection.

Side Effects

---

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.)

What To Think About

---

Among topical medicines, creams may be best used on mild to moderate non-oozing infections, lotions on oozing infections, powders and sprays to prevent reinfection, and gels and ointments for long-term moccasin-type infections .²

It is not known whether these medicines harm a fetus or whether topical medicines pass into breast milk. If you are pregnant, could become pregnant, or are breast-feeding, consult your health professional.
