Sulfathiazole is a short-acting sulfa drug. It used to be a common oral and topical antimicrobial until less toxic alternatives were discovered. It is still occasionally used, sometimes in combination with sulfabenzamide and sulfacetamide, and in aquariums.
Cultural references
Sulfathiazole is mentioned in chapter 104 of Kurt Vonnegut's novel Cat's Cradle, and several of his short stories.
