These are anti-epilepsy drugs such as valproate, carbamazepine, lamotrigine, phenytoin, gabapentin, and pregabalin

; tricyclic antidepressants such as carbamazepine, amitriptyline, and
nortriptyline. The other option is surgery: Stereotactic radiosurgery, cutting or destroying part of nerve or removing blood vessel or tumor pressing it. If there is a tumor or blood vessel causing the symptoms then medical treatment will not help.
