Progress in drug development has brought a host of novel agents for the treatment of neurological disorders ranging from multiple sclerosis to chronic pain.1 However, the treatment of most neurological disorders is still dependent on older medications. This includes medications, such as carbamazepine, with clinical activity across a broad number of disorders. Carbamazepine was first approved in 1963 for the treatment of epilepsy but has been used for treating types of schizophrenia, bipolar disorder, neuropathic pain, tinnitus, and trigeminal neuralgia. Although this agent is safe and effective for many patients, there is a low but persistent incidence of severe cutaneous adverse drug reactions (cADRs), including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms, and hypersensitivity syndrome.2 Data from the US Food and Drug Administration between 2004 and 2013 found an annual SJS/TEN incidence of 1 to 5 cases per 1 million persons in the United States.3 In addition, SJS/TEN is associated with a prolonged length of hospital stay and higher costs of care (SJS, 9.8 days, $21 437; SJS/TEN, 16.5 days, $58 954; TEN, 16.2 days, $53 695) compared with all other admissions (4.7 days, $11 281).4 This raises a challenge of how to use a medication that is safe for most patients but that also carries a risk of extreme morbidity or even mortality.
