Multiple Sclerosis
"**This is a missing side effect that should&#039;ve been noted in the prescription information! *** For the first two years this medication came out I continue to use it along with my disease management drug. I was taking tecfidera.  These two medications combined  drastically slow down your lower intestinal.  Ampyra lists constipation as a minor, less common  side effect. After some research with my doctor he researched the medications in medical journals and the chemical compounds and he thought two should not be taken together for this particular reason."
