It cannot come down on its own. First of all both your predisone and the insulin dosage has to be adjusted till you are on prednisone. Because Prednisone is a steroid and naturally increases blood glucose and the normal insulin dosage will not be sufficient to regulate it.

How dangerous is a blood sugar level of 330? My husband has been without metformin for about a week, but has been taking a shot and a new pill - neither are insulin, the pill helps block sugar from entering your system and the shot helps the metformin.
