Anti-convulsants

Anti-convulsants are a group of drugs that are used to treat seizures, and they can also be used to treat chronic head pain. They’re especially effective for people who have trigeminal neuralgia or other forms of facial pain that’s caused by nerve damage.

The exact mechanism behind anti-convulsant drugs is unclear, but they appear to work by blocking the channels in the brain that signal pain. They also help prevent overactivity in the brainstem that can cause seizures. Anti-convulsants are generally considered safe when taken at prescribed doses, but they can have some side effects such as drowsiness, dizziness, and nausea.
