Hey Debbie,
I have been on and off mtx several times over the past ten yrs. Lately I have been using it to try to get further reduction prednisone. I am down to 6 mg of prednisone, and just dropped the mtx. I honestly can't say it has ever helped me, as I see n o difference in RA symptoms on or off. If you have severe RA, you may want to consider asking rheumy to put you on biologic before you have joint damage. Humira and Enbril have worked wonders for my RA, and even corrected some of the joint damage. Best of all, very few flares and no more pain in joints.
It's not an easy decision, as the rare side effects may include lymphoma, but for me the benefit outweighs the risk.
Best wishes!
Beth
