Serious and sometimes fatal dermatologic reactions (including Stevens-Johnson syndrome and toxic epidermal necrolysis) have been reported, especially in patients with the inherited allelic variant HLA-B*1502. Screen genetically at-risk patients prior to receiving carbamazepine. Do not start carbamazepine in patients who test positive for the allele unless the benefit clearly outweighs the risk. Discontinue if you suspect that the patient has a serious dermatologic reaction. Aplastic anemia and agranulocytosis have also been reported. Obtain pretreatment hematological testing and periodically monitor CBC. Consider drug discontinuation if significant bone marrow depression develops .
