Symptoms: Dystonic reaction, akathisia, oculogyric crisis, jaw clenching
While at the emergency room for an anxiety attack, the doctor gave me prochlorperazine for my nausea that wasn't affected by Zofran. Within 30 minutes my tongue started darting randomly in my mouth. I shrugged it off because I had no idea that could be a symptom of anything. Perhaps I'm just mad. So they sent me home.
After two to three days, a very gradual set of symptoms manifested. On the day that I finally called 911 for help because I was terrified, my eyes were constantly moving upward by themselves, to the point where my head would move up as well. And my teeth were clenching very hard. I started to hold my finger between my teeth to try to stop it. And all the while I felt this deep restlessness, a core feeling that I needed to do something, to move.
Finally all of these symptoms got so severe that I called 911. They were unsurprised. Said that this medication does this a lot, that the meds ending in "-zine" have a bad reputation amongst first responders. The treatment was Benadryl.
After that experience I learned what medication that doctor gave me. A pretty serious antipsychotic because I was nauseated with anxiety. I'm confident that hospital simply had a policy of not allowing patients to leave with symptoms that can be addressed in some way.
