I was on 60 mg for about 6 weeks, and then it took 6 more weeks to get down to 40. My rheumatologist was cautious with my taper due to serious vision problems from the GCA. My vision is ok now. I started taking weekly Actemra injections about a month after starting prednisone. I'll be at 6 mg prednisone in a couple of days. Everything has gone well with my taper so far. I haven't had any pain since beginning treatment about 8 months ago.

I hope you get things figured out soon and find the right treatment.
