What is ProZinc Insulin for Cats? ProZinc is a protamine zinc insulin. It FDA approved for use in diabetic cats. Protamine zinc insulin formulations have a typical duration of effect in the cat of 10-14 hours which helps keep your cat’s blood glucose level consistent throughout the day.

Formulated for: Cats.

How is this medication given? The dose and frequency of administration is individual depending on your cat’s needs so always follow your veterinarian’s precise directions. The initial recommended dose is 0.1 - 0.3 IU insulin/pound of body weight (0.2-0.7 IU/kg) every 12 hours. Gently roll each vial with the palm of your hands before giving each dose. Do not start giving ProZinc to your cat until you are properly trained to do so by your veterinarian. ProZinc injections are given subcutaneously (under the skin). Give ProZinc injections with a U-40 syringe(sold separately) or dosing will be inaccurate. It is best to give each injection of ProZinc at feeding time or just afterward. It is also best to give the injections at the same time every day because it will help your cat maintain the most stable blood glucose levels.

How does this medication work? ProZinc supplements diabetic cats with the insulin that is necessary to control hyperglycemia(high blood sugar). Protamine and zinc help to maintain results for up to 14 hours. This helps your cat to maintain a consistent blood glucose level throughout the day. ProZinc contains recombinant DNA which mimics human insulin and helps to control your cat’s diabetic symptoms.

What results can I expect? ProZinc does not cure diabetes. It will, however, help to control the symptoms or signs associated with this disease which should help your cat to feel better. Adequate control of your cat’s diabetes can be achieved with a combination of insulin injections, diet, and in some cases, weight loss. A small percentage of diabetic cats may no longer require insulin injections after some treatment but this is rare.
