Carbamazepine (CBZ) is one of the standard pharmacological treatments for neuropathic pain. However, its serious adverse drug reactions include Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). Recently, HLA-B*1502 allele was implicated as a genetic marker of CBZ-induced SJS/TEN in some Asian epilepsy populations. ⋯ HLA-B*1502 is a strong genetic marker for CBZ-induced SJS/TEN in Thai patients with neuropathic pain. The screening for this marker should be performed prior to initiation of CBZ treatment to assess the risk of this serious side effect.
