(WIBW) - The U.S. Food and Drug Administration wants to insulin users to take a good look at their medication.
The FDA says stolen vials of the long-acting insulin Levemir made by Novo Nordisk Inc. still may be on the market.
FDA officials say evidence suggests the stolen insulin wasn't stored and handled properly and may be dangerous for people to use. The agency says it's received reports of patients who suffered an adverse reactions due to poor control of glucose levels after using a vial from one of the stolen lots.
The FDA first alerted the public to the theft in June. Three lots of Levemir totaling 129,000 vials had been stolen in North Carolina. So far only about 2 percent of the total amount stolen has been recovered.
The FDA says anyone with information on the theft should contact its Office of Criminal Investigations by calling 800-551-3989 or by visiting the OCI Web site.
The agency is advising patients who use Levemir insulin to:
1. Check your personal supply of insulin to determine if you have Levemir insulin from one of the following lots: XZF0036; XZF0037; XZF0038. You can locate the lot number on the side of the box of insulin and also on the side of the vial.
2. 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 another insulin product may require adjustments in dosing.
3. Always look at your insulin carefully before using it. Levemir is a clear and colorless solution
