Other aromatic anticonvulsants have weaker evidence linking SJS/TEN with the HLA-B*15:02 allele; however, caution should still be used in choosing an alternative agent. Previous tolerance of carbamazepine is not indicative of tolerance to other aromatic anticonvulsants. Aromatic anticonvulsants include carbamazepine, oxcarbazepine, eslicarbazepine, lamotrigine, phenytoin, fosphenytoin, and phenobarbital. In addition to HLA-B*15:02, risk for carbamazepine-induced SJS/TEN has been reported in association with the most common B75 serotype alleles in Southeast Asia, HLA-B*15:08, HLA-B*15:11, and HLA-B*15:21. Although not described, the possibility of carbamazepine-induced SJS/TEN in association with less frequently carried B75 serotype alleles, such as HLA-B*15:30 and HLA-B*15:31, should also be considered.
