Toenail Fungus Treatment – What are my options?

What is toenail fungus and fingernail fungus?

• Fungal infections of the nails (onychomycosis) can be a persistent and sometimes embarrassing problem and occasionally can become painful. These infections develop when fungi, known as dermatophytes, burrow under nails causing them to become crusty, thick, discolored, and distorted.

What are the symptoms of toenail fungus and fingernail fungus?

• The first signs and symptoms of fingernail or toenail fungus is a white or yellow spot appearing underneath the tip of the nail, which then thickens and distorts the nail as the infection progresses. As fungi grow under and into the nail, crusting, discoloration, and darkening begin. Moreover, infected nails often separate from the nail bed, which can cause pain in the tips of fingers and toes, as well as a slightly foul-smelling odor.

What are the causes of fingernail and toenail fungus?

• You can pick up a fungal infection such as toenail fungus while walking barefoot at a swimming pool, in a gym locker room or shower, or even when having a pedicure under less-than-sanitary conditions. The fungus thrives in warm, dark, moist environments, like showers or sweaty shoes. Susceptibility may be heightened among those who have diabetes, an immune deficiency condition, a history of athlete’s foot, or who are prone to excessive perspiration. Foot and toenail fungus usually will travel through an opening in the skin or separation in the nail bed, and if continually exposed to warm and moist environments, will grow in abundance. Infection with nail fungus seems to occur more in toes than fingers because toenails usually are confined to the dark, warm, and moist environments where fungus thrives, as opposed to fingers, which are out in the light and open air. Diminished blood circulation to the toes as compared with the fingers can also make it harder for the body’s immune system to detect and eliminate the infection.

What are the conventional fingernail and toenail fungus treatments?

• There are antifungal creams available over the counter as a fingernail/toenail fungus treatment, but their efficacy is questionable. The oral anti-fungal medications are much more effective as home remedies for toenail fungus, but not without bothersome side effects ranging from skin rashes to liver damage. These fingernail treatments and toenail fungus treatments and medications must be used with caution, especially since toenail fungus treatment is usually long-term. Fluconazole (Diflucan), itraconazole (Sporanox) and terbinafine (Lamisil) are a few commonly prescribed oral antifungal medications. They must be taken anywhere from 6 to 12 weeks as these infections are not quick to clear up.

• There is a “nail lacquer” called ciclopirox (Penlac) that can be painted on the nail, applying it daily for a week. You then wipe the layers off with alcohol and start the process all over again. This tedious process is done for up to a year and only has a 10 percent efficacy rate. Another topical prescription is efinaconazole (Jublia) requiring daily treatment for 48 weeks. Any topical application tends to work better when used in conjunction with oral medications. Serious infections may warrant the removal of the nail.

• Doctors also advise keeping nails trimmed short and allowing time for the feet to dry after showers, baths or swimming, using absorbent socks, and discarding old shoes that may contain fungal spores.

Toenail Fungus Prevention

• Vinegar has been used traditionally to ward off nail fungus. Evidence of efficacy is sketchy at best, but you could try soaking your feet in one part vinegar to two parts warm water for 15 to 20 minutes daily.

Whatever treatment you choose, take these precautions to prevent recurrences:

• Keep your feet as clean and dry as possible

• Wear waterproof sandals at swimming pools or other wet public areas

• Change your socks or hose daily

• Clip toenails straight across and keep them shorter than the tips of your toes

• Avoid tight hosiery, which promotes moisture retention, and wear synthetic fabric socks that wick moisture away from feet better than cotton or wool

  Be especially careful of any nail problem if you have a weakened immune system or diabetes, and have foot concerns already. What might start out as a cosmetic problem can quickly turn into a more serious issue leading to complicated fungal infections mixed with bacteria, skin breakdown, worsening pain, neuropathy, and in the case of advanced diabetes, permanent nail removal or even amputation of the toe.

A final consideration:

Chronic fungal nail infections may be a sign of a chronic gut or other systemic yeast infection. If you think you could benefit from toenail fungus treatment, contact the New Jersey or Pennsylvania podiatrists at Foot & Ankle Centers to schedule a consultation. We believe feet shouldn’t hurt and neither should their treatment.
