Desensitization to sulfasalazine after hypersensitivity reactions in patients with inflammatory bowel disease.

Abstract

Desensitization to sulfasalazine was successful in 40/47 (85%) patients with IBD who previously had hypersensitivity reactions. The desensitization with sulfasalazine was well-tolerated with no serious complications in short- or long-term follow-up. The course of IBD was subsequently favorable in 35/40 (87%) for extended periods including 17/17 (100%) with ulcerative colitis. Desensitization should be attempted in patients who have had typical hypersensitivity reactions to sulfasalazine.
