Carbamazepine works by stabilizing the electrical activity in the brain. It blocks sodium channels, preventing excessive nerve firing that causes seizures. This helps control both seizures and mood swings in conditions like epilepsy and bipolar disorder.

Carbamazepine tablets are typically taken orally with food to reduce stomach irritation. The dosage and frequency depend on the condition being treated and individual response. Usually, it is taken once or twice a day.
