constipation, drug induced
"9-17-2015 The other reviews compel me to expand my comments.  All Movantik does is land on the receptors in your stomach.  These receptors are the ones opioid normally land on which makes it difficult to have a movement.

I still have responsibility for what I eat and taking stool softeners and Senna tablets so my stool is soft.  Otherwise I would be experiencing possible blockages.  It is now 3 weeks and it works  for me.  But you have to pay attention.

Also I am not a doctor.  This just my experience."
