Why Use a Vial Safe Case for ProZinc?

ProZinc (protamine zinc recombinant human insulin) is an FDA-approved veterinary insulin commonly prescribed for diabetes management in cats and dogs. ProZinc vials are fragile and expensive to replace — a single drop can crack the glass and waste an entire vial. Vial Safe silicone protector cases absorb the impact of drops onto hard surfaces like tile, hardwood, and concrete, keeping your pet's insulin safe.

Fits Both 10mL and 20mL ProZinc Vials

Vial Safe is one of the only protector brands offering cases for both the standard 10mL and larger 20mL ProZinc vial sizes. The open-top draw-through design lets you draw doses without removing the vial from the case — label and fill level always visible. Made from hypoallergenic, medical-grade silicone that's easy to clean and built to last.
