I'm type 1 diabetic, always had problems w prednisone raising my blood sugar. I was just prescribed 20 mg a day for 7 days for a SLE flare up. I can't believe this, I'm having quite a few lows! It was interesting to see someone else have the same.
Re: Prednisone's lasting effect on blood glucose. I haven't had a patient on it in a while but from what I remember the effects of the drug seem to wear off rather quickly. Possibly within 24 hrs of discontinuing it. What gets me is when the professionals administering the drug don't let the person with diabetes know that yes, this will raise your blood sugar.
