Treatment of vitiligo with oral 5-methoxypsoralen.
Thirty-six patients with vitiligo were treated with oral 5-methoxypsoralen (5-MOP) and subsequently exposed to UVA irradiation. The patients were treated once or twice weekly over a period of 2-10 months, taking 40-60 mg of 5-MOP 2 hours before exposure to UVA light. The amount of exposure to UVA light was slowly increased according to the patient's tolerance. Eleven (31%) patients showed remarkable repigmentation of the areas of vitiligo within six months. Overall, 78% of the patients showed effective repigmentation. Areas of vitiligo on the face and trunk were more responsive to treatment than those on the distal part of limbs. Adverse effects due to the drug included 2 patients with nausea and 1 patient with headache. It is suggested that treatment with systemic 5-MOP is effective, safe, and useful in selected cases of vitiligo.
