Doctor's View on Tinea Versicolor Treatment

Comment by Gary W. Cole, MD, FAAD

Tinea versicolor is a common skin infection of adults and teenagers (less common in children) caused by a fungus of the genus Malessezia. Since this fungus is a normal inhabitant of the skin of most adults, it is unclear as to the factors that induce the disease. It commonly involves the torso, sparing the head and legs. Though tinea versicolor usually doesn't cause symptoms, it occasionally can itch. The lesions appear as flat, slightly scaly areas of discolored skin, hence the term versicolor. Involved areas can be any color but frequently appear lighter than adjacent normal skin if you have been tanning. It is a chronic condition unless treated. Even with treatment, the disease is predisposed to recur.

Treatment options for tinea versicolor

Topical creams, sprays, shampoos, and foams that contain an azole (clotrimazole, miconazole, ketoconazole, and econazole are some examples) antifungal as the active ingredient are very effective in eliminating this condition. Lotions and shampoos that contain selenium sulfide or zinc pyrithione (for example, Selsun Blue) are also effective. Many of these chemicals are available in over-the-counter products. The only difficulty is applying the medication to the affected areas. For example, if the disease is on your back, you may require some aid with applying the antifungal medicine. Extensive disease obviously makes it harder to apply medication directly to every affected location. Occasionally, if topical therapy fails or if you are unable to apply medication, it may be necessary to add an oral medication (an azole drug). The most efficacious dosage and duration of therapy has not been determined. Since this disease is generally considered more of a cosmetic difficulty, it is prudent to use very small amounts of systemic medication to enhance the topical treatment. After the tinea versicolor seemingly disappears, it would be wise to continue topical treatments less frequently to maintain clearance.
