From what I've read it's an anticonvulsant.  It would be in the same family of medicine as Depakote, which some docs have prescribed for CH.  Depakote did not work for my CH husband.  Hope this works for you.  In the meantime, check out O2 therapy.  There are many experts on this site who can help you with that.  Trust me, it's a lifesaver.  Blessings to you.

I don't get clusters; I merely report on my son Michael, who does. I do take Lyrica, however. I use it for the peripheral neuropathy in my feet generated by a collapsed disc in my sacral spine. It alters the perceived feeling from that of standing barefoot in the snow to a numb tingling. It also robs me of intellect, memory and vocabulary. That's the trade-off. I wouldn't take it if I didn't have to. I'd be surprised if it did much good for cluster headaches.

This is the only item I found which gives an overview of the medical literature on this question.

Suggest you print out and give to your doc. He will be able to get the full article and appreciate the technical data which I have deleted.

i ve tried neurontin with no good results in ch and lyrica later on with many bad side effects.
blanks in thought and oral speech.(being in half of a sentence and forgetting what was that you wanted to say can be pretty upsetting).
too much tired,sleepy and diziness too.coffee could hardly overcome it.
thats all i can remember....both drugs didn't have the sligthest effect on ch.

chiefmurph if you have already made up your mind to stop this med don't do it in a switch but reduce it slowly the way you increased it at first point(if thats the case of course cause at least this is how i did that treatment).
i did the mistake and stop it thoroughly and had some nasty kind of headache the following days.

or
even better just ask the neuros advise.
the spartan way.fewer words.aoo!
