Carbamazepine is used alone or in combination with other medications to treat certain types of seizures in patients with epilepsy. It is also used to treat trigeminal neuralgia (a condition that causes facial nerve pain). Carbamazepine extended-release capsules (Equetro brand only) are used to treat episodes of mania (frenzied, abnormally excited or irritated mood) or mixed episodes (symptoms of mania and depression that happen at the same time) in patients with bipolar I disorder (manic depressive disorder; a disease that causes episodes of depression, episodes of mania, and other abnormal moods).
