constipation, drug induced
"Talk about induced anxiety!!! I have NEVER felt so absolutely horrific as I did when using this medication.

My doctor prescribed it one week after shoulder surgery when I was having severe stomach problems and constipation.  I had already stopped taking percocet when I started taking it.  And when I still wasn't pooping.....you guessed it, Doctor prescribed ADDITIONAL dosage!  I was crying, in a state of panic, unable to sleep---I NEVER EVER want to feel this way again.  

After reading up on it, you are not supposed to take Movantik if you are NOT TAKING OPIODS!!!!  Thank you for the medically induced anxiety horror show."
