IPIR = immediate post injection reaction

its a RARE reaction that can happen within just a few minutes of taking the injection. it can cause chest pain, shortness of breath, sweating, panic...it normally comes on within moments of taking the shot, and lasts anywhere from 10 seconds to 15 minutes.

I have had it happen twice, and both times it was when I smacked into a vein. They dont know what causes it, and assume its when the copaxone gets into the vascular system.

Mine lasted less than 5 mins,and since I knew what it was, I knew how to prep for it.
