I had a clonic/tonic seizure after a very complicated heart transplant was on over 50 meds, intubated for 11 days. My keppra taper will end next week my doctor told me that I would not be able to drive for 3 months even if I have no seizure. Have never had a seizure this was a one time incident due to the cirumstances have been on keppra 750mg twice/day for over 6 mos
