Can gabapentin be an alternative drug for trigeminal neuralgia?

Gabapentin is another medication commonly used for pain of nerve origin, so a neuropathic pain. It can be tried as an alternative; some patients may need a combination of both carbamazepine plus Gabapentin for it to work. Especially if patients have a lot of side effects from carbamazepine where they may need to deal with dizziness or sleepiness.
