Prochlorperazine
"I was talking to my sister about my bad reaction to a medication I took 15 years ago called Compazine. I took this prescribed medicine while at home. I remember my experience like it was yesterday. At first I felt a twitching in my jaws. All at once, my bottom jaw started going to the right, and my top jaw started going to the left. I could not stop it and I could not talk. In fact, my jaw felt like it was trying to break off my face. I remember the emotional and physical pain. Me and my husband were both crying, because we both didn't understand what was happening! My husband ended up taking me to another clinic, and they admitted me at once. So BEWARE! Just from talking - I found out this same medication hurt my sister just last year."
