For the relief of trigeminal neuralgia, the treatment depends on the cause of the trigeminal neuralgia and the degree of pain. If the trigeminal neuralgia is primary and the pain is mild to moderate, treatment can be given with oral medications such as carbamazepine, gabapentin, pregabalin, or a combination of sedative medications such as clonazepam. If the symptoms are not significantly relieved after oral medication, nerve block therapy can also be performed. For secondary trigeminal neuralgia, the cause should be actively removed. If the trigeminal neuralgia is caused by vascular compression, surgical treatment can be performed, mainly by microvascular decompression, but also by severing the peripheral branches of the trigeminal nerve outside the cranium. Therefore, to relieve trigeminal neuralgia, the treatment is mainly based on the cause and the degree of pain.
