You should work with your rheumatologist to see what dose of prednisone you should be taking. He or she can tell you if you still need it for PMR and how fast you should taper. Prednisone can cause osteoporosis, but PMR and GCA are worse problems than osteoporosis, so people with those problems need to take prednisone and other drugs like Actemra. A lot of people taking prednisone also take drugs like Fosamax to help prevent or minimize osteoporosis. That's something else your rheumatologist can help with. I am taking 10 mg per day of prednisone now for GCA and PMR, so my rheumatologist referred me for a bone density test to see if I need to take a drug to strengthen my bones. I'll take that test next week. I tried taking Fosamax pills a few months ago, but they caused acid reflux, so I had to stop. Some people get the drugs to build bone strength through IV infusions. If I need that kind of drug, I'll take it through infusions.
