Carbamazepine-induced Stevens-Johnson syndrome in a patient with history of methotrexate-induced mast cell activation syndrome

Abstract

Stevens-Johnson syndrome (SJS) is serious conditions that happen as a result of infection, side effects to medications, or unknown etiology. Carbamazepine is one of the common medications that can cause SJS. Good history taking is crucial if treatment with carbamazepine is clinically indicated. We would like to alert all physicians that carbamazepine should be avoided in any patient with a previous history of drug reaction such as mast cell activation syndrome.
