Topical treatment with high-potency corticosteroid solution or ointment under occlusion with cellophane wrap at bedtime can improve nail psoriasis. Avoid long, continuous therapy with corticosteroids to avoid tachyphylaxis. Also, avoid prolonged occlusion (not to exceed 2 wk). A topical preparation of a combination of high-potency corticosteroid and calcipotriol may benefit some patients. [19]
