"i received an injection of this medicine because of a debilitating migraine which lasted for more than two weeks.

when this was injected i almost immediately started to feel crazy.

i wanted to leave the hospital immediately, even though my migraine was worse- not better. i actually walked home (hospital was nearby) but my right leg went numb &amp; i literally dragged it behind me all the way home.

this was followed by extreme anxiety, confusion and a full week of insomnia which i had to be treated for. 

obviously, i had one of those &quot;rare&quot; reactions. however, a close friend later had a similar reaction to this medication and had to be put it a straight jacket following administration. 

so, these reactions, while rare, can be extreme."
