Tegretol is an anticonvulsant. It works by decreasing nerve impulses that cause seizures and pain. Tegretol is used to treat certain types of seizures (partial, tonic-clonic, mixed). Tegretol is also used to treat nerve pain such as trigeminal neuralgia and glossopharyngeal neuralgia.

Tegretol dosage. Tegretol is available in tablets, suspension, chewable tablets, and extended-release tablets. Take Tegretol exactly as prescribed. Never alter the dosage. Do not stop taking Tegretol without talking to your doctor. If you have epilepsy, stopping seizure medicine suddenly can cause seizures that will not stop.
