hi swami and welcome aboard.
I have had RA for 25 years now and used to take a lot of ibuprofren to help me make it through the work day. I would just caution you to follow directions with it, eat something before you take it and don't rely too heavily on it in lieu of other avenues with your Doctor.
I eventually developed problems in my gut due to taking it and can no longer use it at all now.
A bummer for me because it was one of the short acting drugs that actually helped.
Hang in there with the tapering off of Pred. The last few MG's can take a while to break free from and you might see some flare ups when you lower your dose. I still use it for bad flares but only for short time spans because it really messed me up with side effects.
