The drug combination sulfacetamide/sulfur is a topical acne medication manufactured by Medicis under the trade name Plexion and also available under other trade names such as Clenia, Prascion, and Avar. It combines sodium sulfacetamide, a sulfonamide antibiotic, and sulfur, a keratolytic agent.[1] It is available in four formulations: as a cleansing cloth, cleanser, topical suspension, and as a facial mask. The sulfacetamide inhibits the growth of the bacterium Propionibacterium acnes that is associated with acne, while sulfur facilitates the removal of dead skin cells to prevent clogged pores.[2]
