Treatment of Bullous Pemphigoid With Dapsone, Methylprednisolone, and Topical Clobetasol Propionate: A Retrospective Study of 62 Cases

Dapsone has been used successfully as adjuvant therapy for bullous pemphigoid (BP). The effectiveness of dapsone for this indication, however, remains controversial. We evaluated the effectiveness and adverse events of dapsone (1.0–1.5 mg/kg per day) in combination with oral methylprednisolone (tapering doses of 0.5 mg/kg per day) and topical clobetasol propionate (initially applied once daily on lesions only) in the treatment of BP. Sixty-two patients treated with this regimen were analyzed retrospectively. Patients were free of new blisters after a mean (±SD) of 22±13 days (median, 20 days).

Dapsone-related side effects were usually mild except in 3 patients (5%), 2 patients with anemia (hemoglobin level,
