A Novo Nordisk A/S (NVO) product previously reported as stolen in North Carolina has resurfaced recently at a medical center in Houston, the company said in a press release Saturday.

Novo Nordisk said three lots of 10 millileter vials of insulin, marketed under the brand name Levemir(R) were taken in the original theft and identifiable by the following lot numbers: XZF0036, XZF0037, XZF0038.

A vial or vials of stolen insulin from lot XZF0037 was discovered this week at a medical center in the Houston area, the company said.

According to the company, Insulin from these lots did not circulate through the normal Novo Nordisk distribution channel and therefore proper storage conditions for the insulin may not have been followed.

The company said patients can locate the lot number on the side of the box of insulin or the side of the vial. If a patient finds their insulin is from one of the stolen lots, they should not use the insulin and contact Novo Nordisk at 1-800-727-6500 for further information and instructions.
