Treatment & Prevention Tips for Fungal Infections of the Skin

The control of dampness is the most important factor in pre­venting fungal infections of the feet and groin. Measures to promote dryness also increase the likelihood of curing these infections. The toes and groin should be very carefully dried after bathing, undressing, and whenever possible if they become moist. The liberal application of a drying powder, such as an antifungal powder, is helpful. Cotton socks and underwear absorb moisture very well, but nylon does not. Boxer shorts are preferred to tight-fitting briefs, because they allow the groin to "breathe."

Likewise, aeration of the feet is very desirable. This can be promoted by going barefooted, wearing sandals, or wearing "ventilated" shoes. Shoes with rubber soles, especially sneakers or tennis shoes, provide poor aeration. Shoes made of nonporous leather, plastic, cordovon, or some synthetic materials also fail to allow proper ventilation of the feet and should be avoided. Cork or felt inserts in the shoes may help absorb some moisture. Cotton or gauze inserted between the toes will help keep the infected areas dry but should be removed upon becoming wet. One must be very persistent with these measures during warmer weather.

There are several medications available without a prescription for the treatment of fungal infections. These medications should be applied liberally according to the directions, with treatment continuing several days after the infection has cleared. Treatment usually takes several weeks.

Raw, oozing, or blistered areas are best treated by soaks followed by solutions, shake lotions, or creams. Thick ointments should be avoided.

Tinea versicolor can be treated successfully with a number of medications, though some work more rapidly than others. Selenium sulfide suspension (2 ½ percent) or shampoo is often successful with only a single overnight application. Most derma­tologists prefer selenium sulfide for the treatment of Tinea versi­color because it is effective and does not require repeated applica­tions. The 2 ½ percent strength suspension which is used for Tinea versicolor requires a prescripton. It should not be applied to the groin because irritation may result.

Sodium thiosulfate in a 25 percent solution is effective, inexpensive and available without a prescription if you can get a pharmacist to prepare it for you. The use of liquid or bar soaps or shampoos that contain sulfur and/or salicylic acid will sometimes eliminate the fungus. These may be applied for a few hours each day or simply used as a bath soap. The overuse of these soaps may cause dryness or chapping. It should be remembered that Tinea versicolor often returns in warm weather; preventive treatments every few months and especially in the spring are useful. After successful treatment, the lighter areas may take some time to regain their normal color.
