How to Order Prescriptions


ProZinc is the first protamine zinc insulin that is approved by the FDA specifically for use in cats that releases slowly over time to maintain a stable, consistent blood glucose level throughout the day. 

The PROZINC syringe

When you give your pet a PROZINC injection, make sure you use the correct type of syringe. PROZINC is a U-40 insulin, meaning that there are 40 units of insulin per milliliter (ml) of product. That is why PROZINC must be injected with a U-40 syringe. This is very important because using another type of syringe will deliver the wrong dose.
