Other aromatic anticonvulsants have very limited evidence, if any, linking SJS/TEN, DRESS, and/or MPE with the HLA-A*31:01 allele, and thus no recommendation can be made with respect to choosing another aromatic anticonvulsant as an alternative agent. Aromatic anticonvulsants include carbamazepine, oxcarbazepine, eslicarbazepine, lamotrigine, phenytoin, fosphenytoin, and phenobarbital. Previous tolerance of carbamazepine is not indicative of tolerance to other aromatic anticonvulsants.
