constipation, drug induced
"Amitiza has worked well for over two years to control constipation which is a direct result of opioids taken for pain control.  However my doctor gave me a box of Movantik to try instead.  NEVER AGAIN!
Within a short period of time my colon began cramping for several hours.  Initially I hoped that a bowel movement would reduce the pain.  It did not! I then got diarrhea.  Not wanting to call 911, I tried to breath deeply as I went from chills to sweats to chills & the cramping continued.Praying not to throw up but when I did, it was SO VIOLENT that it went through one of my nostrils.  I had peritonitis 20 years ago, and it is a toss up which was worse.  Childbirth wasn't as severe.  I'll never again try this pill even at a lesser dosage."
