Gabapentin dosage for trigeminal neuralgia?

The carbamazepine (200mg) I’ve been taking relieved my TN but I don’t like the side effects. I’m wondering now that the TN is controlled if I should go back to gabapentin (600mg). I never seemed to have any side effects from that. Hope you’re doing well.

I'm surprised you're having side effects on 200mg? I take 1,000 with no side effects. Sure a difference in people's reactions to medication.
I wonder if 100 mg in the morning and 100 mg at night or the extended-release version would improve your symptoms. There have also been studies showing increased side effects with generic vs brand drugs. Time-release meds also are known to improve side effects.
If given some time your side effects may decrease in severity or possibly disappear altogether although this could take from weeks to months.
I would guess that switching back to gabapentin wouldn't be a good idea.
I would guess a better alternative would be to ask your doctor if Oxcarbazepine would be a good alternative since it's supposed to be as effective as carbamazepine with fewer side effects.
Best of luck to you,
