Early in July, Mylan Pharmaceuticals, Inc. voluntarily recalled a batch of its prefilled Insulin Glargine Injection pens that come in 100 units/mL, 3 mL. The pens include an insulin analog that is long-acting. Doctors prescribe it for glycemic controls in both adults and children who have type 1 or type diabetes. 

The pens in questions are packed five pens to a carton and sold to patients with diabetes. The carton includes information about the product, batch number, and the date the pens expire. The manufacturer recalled a batch that omitted a label on certain pens. Due to this lack of labeling, a patient could mix up the products and strengths of the unbranded pens. This, in turn, could lead to insufficient glycemic control, and either excessively high or low blood sugar.
