PZI-VET and Vetsulin Insulin

On April 8, 2008 IDEXX Pharmaceuticals, Inc. announced that they were discontinuing production of PZI-VET. PZI-VET a brand of U-40 Protamine Zinc Insulin was FDA approved for use in cats. There are still supplies at the retail level. However, once those supplies run out, PZI-VET will no longer be available. That's the bad news.

The good news is that Vetsulin, manufactured by Intervet/Schering-Plough, which was previously approved for use in dogs only, has received FDA approval for use in both dogs and cats.

PZI-VET and Vetsulin are not the exact same insulin. PZI-VET is protamine zinc insulin, whereas Vetsulin is porcine zinc insulin suspension.

As cats are moved from PZI-Vet to Vetsulin, the dose of Vetsulin will need to be adjusted and monitored by the veterinarian.
