Intralesional Corticosteroids in the Treatment of Nodulocystic Acne

Abstract

• We evaluated the effectiveness of intralesional injections of corticosteroids in the therapy for nodulocystic acne. Triamcinolone acetonide at a concentration of 0.63 mg/mL was as efficacious as a higher concentration of 2.5 mg/mL. Betamethasone phosphate had little, if any, effect on nodulocystic acne lesions at concentrations of 3.0, 1.5, and 0.75 mg/mL, when compared with saline controls. (Arch Dermatol 1983;119:480-481)
