seizures
"I was placed on this medication due to my epilepsy. At first I didn't notice anything huge, other than I was stuttering more and "losing words". Then the intense dizziness and vertigo was hitting me every day. I'd randomly feel like I was under water and someone was spinning me. Once I made sure my balance was ok, I would have a very difficult time with my thought processes or communicating. This would last a while after the dizzy incidents. I was only on 200mg once a day. After I spoke with my neurologist, they stated that other patients on this medication have been reporting the same things. I was removed from it immediately. That was about a month and a half ago. The dizzy spells STILL happen a couple times a week."
