Sulfasalazine hepatotoxicity.

Hepatotoxicity has been recently described as a rare complication of sulfasalazine therapy. Two patients with hepatic damage after sulfasalazine treatment are reported. Liver biopsy performed in one patient revealed granulomatous hepatitis. On rechallenge with 5 aminosalicylic acid enema the second patient developed a hypersensitivity reaction without hepatic involvement.
