Was the 1st treatment prescribed for my RA. I did not tolerate it well at all. It made me 10 times more exhausted than I already was ... Which I didn't think was possible. Didn't control my flares .Ended up in ER day after Christmas 2015.
Even though it wasn't effective for me, doesn't mean it wouldn't be effective for someone else. Treatment for RA is very individualized.
Hope that helps.
