Treatment
The first line treatment is topical antifungal therapy. The topical azole antifungals work well in pityriasis versicolor,and there is no significant difference in results achieved by different azoles. The usual time to recovery is 2–3 weeks. A practical problem with the use of topical antifungals is the difficulty of applying creams to a wide body surface area. An alternative solution to this is ketoconazole shampoo which is lathered into the skin in a shower and then washed off after 3–4 min,and although it has not been fully evaluated in pityriasis versicolor,two or three applications of the shampoo appear to clear most infections. Terbinafine 1% cream,but not oral terbinafine,is also effective. Another approach is the application of 2.5% selenium sulfide in a detergent base (Selsun? shampoo). It is applied to all the affected areas and left overnight. Alternatives include 50: 50 propylene glycol in water. The latter has also been used intermittently as long-term suppressive therapy to prevent relapse (Faergemann and Fredriksson,).
Oral itraconazole is also very effective in cases of pityriasis versicolor 100 mg daily for 10 days (Delescluse,) although it is usually given in extensive or recalcitrant cases. Fluconazole has also been used.
Whatever medication is given patients should be warned that normalization of pigmentation may take several months after the end of treatment.","department":"
