Dear billi, haven't been on here in several days.
So sorry you are now left to deal with something longterm.
Don't really know anything about this med.
There are many anti-seizure meds out there & a lot of them are generic.
With these concerns consider calling your doc about this med or trying another one.
I have fibro & take an anti-seizure med that works well & is generic.

Don't give up, you are doing so well taking care of your body.
Don't give up on a med to help with your pain.

Sending healing, peaceful thoughts your way.
