Gabapentin dosage for trigeminal neuralgia?

I've been taking 2400 mg of Gabapentin per day for TN. I've had no pain at all for a year. Then in December I had a very aggressive flareup. I was desperate and called my doctor. He increased my dose to 3300mg. Per day. It worked after 3 days I was pain free again . But I'm worried and scared that I'm on such a high dose. Where do I go from here if I have another awful TN attack in the future? Isn't the maximum dose per day 3600mg? Does anyone know?

Hello @mlougefre, Welcome to Connect. Drugs.com mentions a different maximum dose for gabapentin for different conditions with 2400 to 3600 mg/day for epilepsy, 1800 mg per day for Postherpetic Neuralgia and 600 mg daily for Restless Leg Syndrome.
