Medications
Antifungal medicines that are used on the skin (topical) are
usually the first choice for treating
athlete's foot (tinea pedis). They are available in
prescription or non-prescription forms. Non-prescription medicines are usually
tried first.
For severe cases of athlete's foot, your doctor may prescribe oral
antifungals (pills). However, treatment with this medicine is expensive,
requires periodic testing for dangerous
side
effects, and does not guarantee a cure.
When treating athlete's foot, it is important to use all the
medicine. Using it as directed, even after the symptoms have gone away,
increases the likelihood that you will kill the fungi and that the infection
will not return.
Medication Choices
Non-prescription antifungals usually are tried first.
These include miconazole (Micatin, Monistat Derm), clotrimazole (Canesten),
naftifine (Naftin), butenafine (Dr. Scholl's Athlete's Foot Cream), and
tolnaftate (Tinactin). Non-prescription antifungals are applied to the skin
(topical medicines).
Prescription antifungals may be tried if non-prescription
medicines are not successful or if you have a severe infection. Some of these
medicines are
topical antifungals, which are put directly on the
skin. Examples include econazole (Ecostatin Cream), ketoconazole (Nizoral
Cream), and terbinafine (Lamisil). Prescription antifungals can also be taken
as a pill, which are called
oral
antifungals. Examples of oral antifungals include terbinafine
hydrochloride (Lamisil), itraconazole (Sporanox), and fluconazole
(Diflucan).
What To Think About
You may choose not to treat athlete's foot if your symptoms don't
bother you and you have no health problems that increase your risk of severe
foot infection, such as
diabetes. However, an untreated athlete's foot
infection causing skin blisters or cracks can lead to severe bacterial
infection. Also, if you don't treat athlete's foot, you can spread it to other
people.
If your symptoms do not improve after 2 weeks of treatment or
have not gone away after 4 weeks of treatment, call your health
professional.
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

Some topical antifungal medicines work faster (1 to 2 weeks) than
other topical medicines (4 to 8 weeks). All of the faster-acting medicines have
similar cure rates.2 The fast-acting medicines may
cost more than the slower-acting ones, but you use less of these medicines to
fully treat a fungal infection. Oral antifungal medicines are generally taken
for 2 to 8 weeks.
