Fungal nail infections, also known as onychomycosis, are caused by fungi that infect the nails of the toes or fingers. They are common, and can cause the nails to become thick, discolored, and brittle. Fungal nail infections can be difficult to treat and may recur if not properly managed.
To diagnose a fungal nail infection, a podiatrist or other foot care specialist may examine the infected nail and may take a sample of the infected tissue for laboratory testing.
There are several treatment options for fungal nail infections, including:
Antifungal medication: Antifungal medication can be taken orally (by mouth) or applied topically (to the affected area). Oral antifungal medication is more effective, but can have side effects, including liver damage. Topical antifungal medication is less effective, but is generally safer. It is important to complete the full course of treatment as prescribed by the healthcare provider, even if the infection appears to have cleared up.
