Never ever again will I take companzine. I was given it for nausea at night in ER. First my eye began twitching. I went the next day to my family doctor and told him. He gave me more- told me that was normal. Within 2 hours, I had to go to the emergency room. My eyes were rolling into the back of my head and my neck muscles were spasming so badly (I looked like a gopher ducking from planes). They did not even ask to see insurance or sign in. They started shooting me up with benadryl in both hands. Finally the reaction stopped. This is a dangerous drug/
