Treatment:

Over-the-counter creams and ointments generally do not help treat this condition.

Prescription antifungal medicines taken by mouth may help clear the fungus in about 50% of patients. However, such medicines can cause side effects or may interfere with other medications. Some of the oral medications used to treat fungal infections of the nail can harm the liver.

In some cases, the health care provider may remove the nail. Nails grow slowly. Even if treatment is successful, a new, clearer nail may take up to a year to grow in.

Expectations (prognosis):

The fungal nail infection is cured by the growth of new, non-infected nails.

Fungal nail infections may be difficult to treat. Even with successful treatment, it is common for the fungus to return.

Complications:

• Fungal infections that return on the nails or in other parts of the body
• Permanent damage to the nails
• Skin infections, including paronychia

Calling your health care provider:

Call your health care provider if:

• You experience persistent fungal nail infections
• Your fingers become painful, red, or drain pus
