My initial course was supposed to be 8 weeks, starting at 40mg and tapering 5mg per week. However, it has taken a long time for me to get my maintenance medicine (Cimzia), so when I got down to 5mg, my doctor told me to keep taking 5mg daily. I've been on prednisone now for almost 14 weeks. I don't see him again until 2/15, so it will be at least another 5 weeks at 5mg, then I'm hoping to taper even more then stop completely.
