My neuro just prescribed me olanzapine as a new attempt to find a preventative that might work for me. It's off label, the drug is typically a mood stablizer but there is evidence that it can help alleviate migraines for some who have had trouble with other preventatives. I'm a tough case apparently, I've been on Topamax and Cymbalta for years but lately they've stopped working. That isn't atypical in my history, often something works for a few months or a few years and pushes me back to episodic and then slowly over time the headaches creep back up again, happening more and more often.
Has anyone else been prescribed this drug as a preventative and had success? What was your experience like? I know there are serious warnings about weight gain as a side effect which has me concerned, especially since I already have 'Lose 30 pounds' on my Winter to Spring 'to do' list.
I'd love to hear from members of the community who have walked this road before if anyone has.
