Treat athlete's foot right away, when itchiness first appears.
Most cases of athlete's foot can be cured with over-the-counter antifungal products and basic good hygiene.
Antifungal creams, powders and sprays are all effective at managing the infection. You may need to continue treatment for some time after the rash has cleared to prevent it from recurring. Ensure that you follow the treatment instructions.
Most of the time it responds well to these over-the-counter interventions; however, more severe or resistant cases will need to be seen by your doctor.
As long as the area is not blistered or cracked, remove flakes of dead skin with a soft brush before using a topical powder or ointment. Do not tear off flaking skin; you may break nearby healthy skin and spread the infection.
If not treated properly and promptly, the infection can be very stubborn. Even when treated with antifungal medicines, the infection may take some weeks to disappear and may come back after treatment.
