Could the Mirena IUD cause constipation? #803/7
I had my Mirena IUD inserted in August of 2005, 3 months after birth of daughter. After 21 months of satisfaction, an abdominal pain woke me up one morning. Maybe it was a rupturing ovarian cyst. I took about 8 pepto bismol pills, nearly developed an impaction a few days later and for the next 2.5 months have had constipation despite fibercon, prune juice use. I think it is weird that it took so long to develop these side-affects. It makes sense that that it is a side-effect since progesterone slows down peristalsis. I haven't seen many others complain of this.

You are right that progesterone slows peristalsis, but in much, much higher levels.  I had not heard of this complaint prior to your question. Nor is it among the many, many adverse side-effects and complications listed in the Mirena package insert.  However, I asked a colleague who has inserted numerous Mirena IUDs and rather dramatic constipation is a side-effect she herself experienced.  Her Mirena was removed, a ParaGard IUD inserted and she stopped having the problem of constipation.


            Let me know what you decide to do.


Dr. Phil Darney, have you ever heard of this problem?  The clinician who experienced constipation really liked her Mirena but is convinced that it was the cause of her constipation.


Reply from Dr. Darney on 9-10: Constipation was not reported as a side-effect in any Mirena trials and I've not had anyone complain.  It must be something else.


Reply from Dr. Andrew Kaunitz on 10-19: I agree with Phil; constipation not likely to be Mirena related.
