Carbamazepine is a medication used primarily in the treatment of epilepsy and neuropathic pain. It works by reducing the spread of seizure activity in the brain and by blocking the transmission of pain signals along nerves. Carbamazepine is an anticonvulsant drug and is also used in the treatment of bipolar disorder and trigeminal neuralgia. It is available in various forms, including tablets, capsules, and liquid formulations. Common side effects of carbamazepine include dizziness, drowsiness, nausea, and skin rashes. More serious side effects, such as blood disorders and liver damage, are less common but can occur.
