Nationwide Recall of Insulin Glargine (Insulin glargine-yfgn) Injection Pens

Mylan Pharmaceuticals Inc., a Viatris company, is voluntarily recalling one batch of Insulin Glargine (Insulin glargine-yfgn) Injection, 100 units/mL (U-100), 3 mL prefilled pens which are packaged in cartons of five pens to the consumer level.

This product is not the branded Semglee® pen but the unbranded Insulin Glargine-yfgn pens. This batch is being recalled due to the potential for the label to be missing on some pens.

Risk Statement: For patients receiving treatment with more than one type of insulin (e.g., both short and long-acting insulin), a missing label on Insulin Glargine pens could lead to a mix-up of products/strengths, which may result in less optimal glycemic control (either high or low blood sugar) which could result in serious complications.

To date, no adverse events related to this recall have been received for this product.

This recall pertains only to the unbranded interchangeable biosimilar Insulin Glargine-yfgn pens and does not impact the branded interchangeable biosimilar Semglee® (insulin glargine-yfgn) injection pens.

This product is a long-acting human insulin analog indicated to improve glycemic control in adults and pediatric patients with type 1 diabetes mellitus and in adults with type 2 diabetes mellitus.
