Fungal infection of the toenails and fingernails is referred to as onychomycosis. It appears as white or yellowed nails that may be thickened and brittle. One or more nails may be involved, and different parts of a nail may be affected.

Toenails are the most vulnerable to fungal infection because shoes and socks trap moisture that promotes the growth of fungi.

If left untreated, fungal infections can lead to permanent nail damage.

Fungal infections of the nails are difficult to treat, and recurrence is common. Most antifungal medications applied directly to the nail (topical) are not very effective because they cannot penetrate the hard nail in sufficient concentration to kill the fungi. There are, however, some formulations specifically designed to penetrate the nail.

If the fungal infections have already reached the nail bed (the place where the nail starts growing), oral medications may be prescribed. These medications reach the nail bed through the bloodstream and require some lab monitoring of liver function with the need for alcohol avoidance.

Laser treatment for nail fungus is now offered for localized treatment usually requiring several sessions.
