Hi,I take Neurontin and Effexor XR for a mood disorder.I notice that both may possibly contribute to IBS. As I am constipated (badly), I am thinking of reducing or going off one or the other medication and replacing it with meds with less side effects. Does anyone have any feedback about either of these drugs and constipation? (I notice an earlier discussion was started someone considering Effexor and wanted to expand the topic to include Neurontin.)Any input would be most helpful. I do have a doctors appt today but these drugs effect everyone differently it seems and the usual response is "well, it COULD be causing constipation. that's possible." Therefore, I am wondering if anyone has any first-hand experience with these side effects.Thanks!
