Lamotrigine-associated anticonvulsant hypersensitivity syndrome

Abstract

We systematically reviewed and analyzed published and unpublished cases of lamotrigine-associated adverse drug reactions consistent with the features of the anticonvulsant hypersensitivity syndrome (AHS) to identify characteristics of the syndrome. We identified 26 cases (mean age, 28 ± 18 years; range, 3.5 to 74 years; 54% female), of which nine were published. The characteristics of the syndrome associated with lamotrigine are comparable to AHS induced by older aromatic anticonvulsants.
