I'm not sure how to respond here to each message I received, so forgive me if this is general. I don't recall the dose of Prednisone I took for poison ivy. It was years ago. But it made by heart go into vt, break out in a sweat, head pound and body shake. It was awful. It was one of those packs you take 4 than 3 than 2 than 1. I have noticed the 5 mil of Prednisone recently prescribed for OMR so far has indeed minimized the pain. I am moving better and today I don't feel the need to even take another pain aid like Tylenol. I couldn't get thru the morning before without that assistance and a hot shower. So far so good. My doctor wants me to increase it to 10 mil but since it's working so good at 5, I really don't want to take the chance.
