Constipation, Drug Induced
"I&#039;d never been regular, my whole life, it was always a problem that I was lucky if it resolved itself every 3 or 4 days, but then once I aged and my rheumatoid arthritis advanced to a debilitating degree, I had to go on opiates...oh dear. 7-8 days or even more of being bound up became the norm. It was REALLY painful! The only way I could help myself was to stop taking my pain meds and overdose on laxatives and enemas every few days.
That usually worked within 24 hrs, but it really isn&#039;t good for you.
I finally confessed to my gastroenterologist that this was going on and he prescribed me Amitiza. 
It took a week to work for me, but now I have the exact opposite problem. I&#039;m on 24 mcg 2x daily. I think maybe it needs to be just once!"
