I've been taking Phenytoin for about 15 years because I had two seizures about 15 years ago. Now I suffer from anxiety so I'm on Klonopin 2 mgs daily, gabapentin 400 mgs 3x daily, and lexapro, which I've been taking for about 11 years. I don't think the lexapro does much anymore but I've tried others with no luck. I also take buspar 45 mg daily. I'm going to my neurologist next week and I'm going to ask if I need to keep taking the Phenytoin . Gabapentin and Klonopin are both anti seizure meds if I understand correctly. So I was thinking maybe I could quit.
