I recently took 750 mg tablets of Levaquin for six days for bronchitis. The bronchitis went away but on the 7th day I had a gelastic seizure. I had never had a seizure in my life. I passed out, my wife called 911 and I went to the emergency room for help by ambulance. Enroute I threw up really bad. Once I was checked in they ran a cat-scan and found nothing. The admitted my into the hospital for more tests and observation. The next day I had an MRI with contrast, and eeg, and the tests were normal. The following morning my doctors came in and told me the results of the tests and they were going to send me home. The doctors really did not know what caused the seizure. The Doctor that prescribed it to me said he uses Levaquin all the time and none of his patients had a problem with it. I told him that since that is the only thing that changed, my opinion was it did and that I would never take it again. Unfortunately I can't drive for six months and I now take Dilantin to prevent any more seizures.
