Ive been doing copaxone for 5 years everyday never had flushing or hard to breath. I started the 40ml evey 3 days for about a month and the site reactions aren't as bad. That's my opinion.

I was on copaxone and had major flushing and redness and I gained 10 pounds in the first month !

Been on three months! Side effect free! Fingers crossed! But watch injection sites I made a mistake and injected it to close to my elbow. Causing spasams and severe pain, for an hour or so and bruising next day! The flush as the nurse told me. Can happen time to time. And goes fast. Eat before and make sure its at room temp. I take mine after a hot shower warming the area of injection site. Seems to work really well. A heating pad or the shared solutions heating and cooling bag.
