Helen and Melissa,
You may be interested in posting this on the CDMB, FDMB. It was posted on a vet's blog on Catster.com
Vetsulin insulin is widely used in diabetic dogs (and, occasionally, diabetic cats). I was therefore disturbed to receive the following e-mail from the American Veterinary Medical Association.
FDA-CVM Issues Alert About Problems with Vetsulin® Porcine Insulin Zinc Suspension
November 3, 2009 - The U.S. Food and Drug Administration's Center for Veterinary Medicine, in cooperation with Intervet/Schering-Plough Animal Health, has announced that Vetsulin® may have varying amounts of crystalline zinc insulin, the active ingredient, in the formula. As a result, use of the product could result in a delay in action of the drug as well as prolonged action, which could cause difficulty in managing diabetic pets.
