I’m not saying constipation, per se, is a “serious” side effect, but here is a link to my post on the Emgality topic/thread (help James on site terminology):

> Update after another night in the ER. I agreed with my migraine clinic to add Emgality to my preventative meds even though the every other day Nurtec 75mg was really not at its’ full effectiveness time. I really wish I had just been patient and waited. I was seeing results with Nurtec. It wasn’t until my second month on Emgality that I really started having issues with constipation. I did everything I was told to do by my GI to prevent constipation. Finally, it got to a point where I went into…

Also, I was quite interested to read about the lower back pain @GetBetter since my pain management doctor is preparing to do more nerve blocks as my lower back pain has suddenly seemed to increase. I never thought of the Emgality, but the time frame fits.

Good info, thanks everyone!
