seizures
"I tried this drug as part of a clinical trial for my 9 year old son. On the second night of taking the medicine he woke up having an over 7 minute seizure and stopped breathing during one of the clusters. His seizures were lasting 1 to 2 minutes prior and he has never stopped breathing. I had to call 911 which I've never had to do before. It was very scary. We have dropped out of the trial. I'm disappointed I was hoping this would help us as well as others."
