Is gabapentin addictive? Is it good for migraines?

Hi, Polk!
Gabapentin is only available by prescription
It can be habituating so your doctor may try you on a low dose to see how you respond before increasing your dosage if needed. Never stop the medication abruptly... you'll need a deceasing dose schedule from your doctor.

I’ve been on Gabapentin (600mg) for over a year now and it has helped me. I started experiencing nerve pain in my face after a terrible 8 month migraine cycle where I had daily migraines. I started Gabapentin for the nerve pain and as a preventative for the migraines. I also receive Botox shots every 3 months and take Cymbalta. The combination has been very effective at reducing the frequency of my migraines.
