backed me up... big time. before movantik, i tried to treat it myself. no go. but i didn't back down. i talked to my doctor. she said: one, movantik was specifically designed for opioid-induced constipation... oic. number two? my movantik savings card can save me big time over the other things i tried. don't take movantik if you have or had a bowel blockage. serious side effects include opioid withdrawal, severe stomach pain, severe diarrhea, and stomach or intestinal tears. tell your doctor about side effects and medicines you take. movantik may interact with them causing side effects. don't back down from oic. talk to your doctor about mo-van-tik. and how you can have a $0 co-pay.
