The stolen insulin vials may not have been stored and handled properly and may be dangerous for people to use. Three lots, or a total of 129,000 vials, of the insulin were stolen. FDA has received one report of a patient who suffered a dangerous side effect due to poor control of glucose levels after using a vial of the stolen insulin.
FDA advises people who use Levemir insulin to:
- Check your personal supply of insulin to determine if you have Levemir insulin from one of the following lots: XZF0036, XZF0037, or XZF0038. You can locate the lot number on the side of the box of insulin and also on the side of the vial.
- Do not use your Levemir insulin if it is from one of these lots. Replace it with a vial of Levemir insulin from another lot. If you must switch to another brand of insulin for any reason, first contact your health care provider because you may need a different dose of another insulin product.
- Always look at your insulin carefully before using it. Levemir is a clear and colorless solution.
