migraine
"Like the other anonymous user, I went to the ER with a migraine. I received this medicine and Benadryl (Diphenhydramine) intravenously. The side effects were intolerable. Within minutes of injection a combination of agitation, nervousness and anxiety overwhelmed my already throbbing head. I felt trapped, as if there was no escaping the discomfort of the side effects. 

I gave this a 3/10 because it still prevented me from throwing up after I already had several times. It works, but I won't ever use it again.

I know it wasn't the Benadryl as I have taken it since without incident."
