t know much about
Rebif but I have been on Copaxone for over a year. The
side effects are redness, itching, stinging, swelling at the injection site. There isn't any problems with the liver that I know of. There are some reactions for some that include tightness of the chest, flushing.
I chose Copaxone over the other DMD's due to the lack of side effects such as flu symptoms, liver function..
Good Luck in your decision!
