Hi @safari1949, I'm so glad that you checked with your pharmacist. It is reassuring to know that there are no interaction issues with the drugs you're on for 2 different conditions. Pharmacists are a wealth of knowledge and readily available to answer such questions as part of your health care team.

I also was curious and asked your question to a pharmacist here at Mayo Clinic. She offered this additional information.
"Corticosteroids provide effective treatment for such a diverse array of conditions. As you know side effects depend on the dose, duration and route and of course vary by individual as well. Over a long steroid course patients could see high blood sugar, osteoporosis, infections and slowed wound healing.

Some information suggests that medications that suppress the immune system like prednisone may actually protect against Parkinson’s disease but more study is needed. See this article by Washington University School of Medicine
