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.
This is a tough question. There is increasing evidence on the negative effects of low dose prednisone. But I do not think this is a black and white issue. Low dose prednisone can cause weight gain, increased blood pressure, worsening diabetes, osteoporosis and increase risk of heart disease. Thus, if you have one of these problems already or have other risk factors for these problems, then prednisone could make matters worse.
