There are thousands of pets diagnosed with diabetes each year. PZI(Protamine Zinc Insulin) is an important medication in the control of many with diabetes. For some animals, PZI is the only insulin product that works. There must be a way to keep this medication on the market. PZI VET is derived from bovine and porcine pancreatic glands. At this time, there are no FDA-approved facilities for harvesting bovine pancreatic tissue. Where as it is necessary for the lives of some of our most beloved pets; and where as there are no comparable substitutions, we ask the FDA to make harvesting bovine pancreatic tissue possible. As Idexx is the only company that makes PZI we ask that they either give up the patent or continue to make the life saving product. This medication is not optional, it is necessary for life. On behalf of the animals with loving families who already devote so much to their care, do not let this medication expire.
