The first choice for the treatment of trigeminal neuralgia is drug therapy, in which carbamazepine is the first choice. The clinical effect is relatively positive. In addition, phenytoin sodium can also be taken orally, which is also one of the commonly used drugs and has good analgesic effect. Both drugs can be used to treat most trigeminal neuralgia. However, due to the possibility that such drugs may cause drowsiness, itching, liver damage and other adverse reactions, it is recommended that doctors give specific drug recommendations after necessary relevant examinations according to the specific situation. If the medication is ineffective or the effect is not good, you can also choose other treatments, and the analgesic effect is more accurate. It is recommended to use it under the guidance of professional doctors.
