Anyone who is hypoglycemic ever had any problems after taking two rounds of prednisone?

My daughter is hypoglycemic and over the past three weeks has been having trouble controlling it. The diet has not changed. The only meds. she's been on recently is prednisone. This stuff is supposed to be out of a person's system within 24 to 48 hours after finished taking it. She has been having trouble ever since she took this medicine and she has been done with this medicine for a while. All her blood work came out great. Any feed back?
