Michelle,
I have never gotten completely off for more than two wks. So once you stop completely taking the pred, if you do not get any symptoms at all, then I believe it MAY be safe to say it won't come back. My Dr. says if I need to take anywhere from 2 1/2mg to 5mg for LIFE, it should not hurt anything. He tells me this is a VERY low dose, and can be taken safely. I want to add though, I do have some osteoporosis. I take Boniva 150mg monthly. My cardio says I should be taking something for this, and it is safe to take with a tissue valve. I suppose the pred could have aggravated the condition further, but I doubt the short time I was on the higher dose actually CAUSED it. Remember my neighbor in her seventies, that been on the pred for many years. She has just slight signs of osteopina. I believe you are pre-disposed to bone loss, which is mainly an inherited disease.
