For people with toenail fungus, there is no good time to wear sandals. Not even at the beach in July.
Toenail fungus causes nails to become thick, yellow and brittle in a way that looks pretty ugly and can be painful. Sufferers can spend years and hundreds of dollars trying to clear the infection with drugs, topical treatments and home remedies, sometimes to no avail. It tends to be a cosmetic issue for the younger set and a pain issue for older folks.
There may be hope. Podiatrists have begun using a laser treatment that combats the infection — or wastes their patients’ money because it doesn’t work, depending on whom you ask.
The treatment, in which the podiatrist aims a laser beam at the patient’s toenails to kill the organisms that cause the fungus. The nails aren’t immediately clear after the treatment, which takes up to an hour; the patient must wait for the fungus-free nails to grow out.
Last year, the Food and Drug Administration cleared the first laser, PinPointe, for “temporary increase of clear nail” in patients with onychomycosis, the medical term for a fungal infection of the nail. The FDA cleared a second one, GenesisPlus, in April. Practitioners have been using other lasers on toenail fungus since about 2009.
The most common oral treatment, Lamisil, works for about two out of three patients, according to Lamisil’s FDA-approved prescribing information, but it has been associated with rare cases of serious liver problems. Other potential side effects include diarrhea, headache, rashes and changes in taste. According to Lamisil’s manufacturer, Novartis, the relapse rate is 15 percent one year after completing treatment.
In one small study about laser treatment for toenail fungus, which appeared last year in the Journal of the American Podiatric Medical Association, “26 eligible toes (ten mild, seven moderate, and nine severe)” were treated with a laser produced by Nomir Medical Technologies, which is still seeking FDA approval. After six months, 85 percent of the toenails had improved.
Even John Strisower, the founder of PinPointe USA, says patients should expect at least a minimal reinfection within five years after laser treatment.
