Carbamazepine, sold under the brand name Tegretol among others, is an anticonvulsant medication used in the treatment of epilepsy and neuropathic pain.[4][1] It is used as an adjunctive treatment in schizophrenia along with other medications and as a second-line agent in bipolar disorder.[6][1] Carbamazepine appears to work as well as phenytoin and valproate for focal and generalized seizures.[7] It is not effective for absence or myoclonic seizures.[1]

Carbamazepine was discovered in 1953 by Swiss chemist Walter Schindler.[8][9] It was first marketed in 1962.[10] It is available as a generic medication.[11] It is on the World Health Organization's List of Essential Medicines.[12] In 2020, it was the 185th most commonly prescribed medication in the United States, with more than 2 million prescriptions.[13][14]
