PRESCRIPTION NEEDED (POM-V)
ProZinc insulin for cats and dogs (40 IU/ml suspension for injection, 10ml) is a POM-V veterinary medicine used to help manage diabetes mellitus. Because dosing must be precise, it is usually given as a twice-daily injection under the skin, with the amount set and adjusted by your vet for each pet.
ProZinc insulin for cats and dogs is part of a wider diabetes plan that also includes diet, routine and regular monitoring, so it must only be used for the pet named on the prescription and exactly as your vet advises.

ProZinc 40 IU/ml Insulin for Cats and Dogs
POM-V Prescription Needed

ProZinc insulin for cats and dogs is a veterinary insulin suspension used to help control blood sugar levels in diabetic pets. Diabetes happens when the body cannot make enough insulin, or cannot use it properly, so blood sugar rises and your pet may become thirsty, hungry and lose weight. Because ProZinc is a prescription-only veterinary medicine, it is only ever supplied and supervised by a vet.
PRESCRIPTION NEEDED (POM-V)
What is ProZinc insulin for cats and dogs?
ProZinc insulin for cats and dogs contains protamine zinc insulin (human insulin) at a strength of 40 IU/ml, supplied as a suspension for injection in a 10 ml vial. It is manufactured by Boehringer Ingelheim and authorised in Great Britain as a POM-V veterinary medicine.
After injection under the skin, the insulin is absorbed slowly into the bloodstream. It then allows sugar to move out of the blood and into body cells, where it is used for energy. As a result, blood glucose levels fall towards a safer range, which is why insulin therapy is central to managing diabetes mellitus in cats and dogs.
What is ProZinc insulin used for?
ProZinc is authorised for the treatment of diabetes mellitus in cats and dogs, to reduce hyperglycaemia (high blood sugar) and improve the clinical signs associated with it. Under veterinary guidance, this injectable insulin can help:
- Reduce excessive thirst and urination
- Support a more stable appetite and weight
- Improve energy levels and day-to-day wellbeing
- Provide a predictable insulin profile as part of a twice-daily routine in most cases
However, diabetes management is always individual. Your vet will confirm the diagnosis with blood and urine tests, then design and monitor a tailored treatment plan for your pet.

Prescription Required – POM-V
ProZinc insulin for cats and dogs is a POM-V medicine, so a veterinary prescription is always required before we can dispatch it. If your vet already prescribes ProZinc for your pet, you can send us your prescription through our Pet Prescriptions page, and our team will check it before your order is processed. We are unable to supply this product without a valid, current prescription.
Using ProZinc Insulin for Cats and Dogs Safely
Because insulin therapy needs to be precise, your vet will show you exactly how to store, mix and inject ProZinc before you start treatment at home. In general, you will need to:
- Follow the injection instructions your vet has shown you, step by step
- Keep feeding and injection times as consistent as possible
- Gently roll the vial as directed to mix the suspension before each dose
- Use the correct U-40 insulin syringes, as advised by your vet
- Monitor your pet’s behaviour, appetite and thirst, and attend review appointments
Suitable U-40 syringes for this product are available separately as ProZinc 0.3ml U-40 insulin syringes and ProZinc 1ml U-40 insulin syringes. Never guess with insulin dosing – if you are ever unsure about a dose or an injection, contact your vet before giving the next one.
Storing ProZinc Insulin for Cats and Dogs Safely
ProZinc insulin for cats and dogs is a temperature-sensitive medicine, so correct storage matters. According to the current datasheet, you should:
- Store the vial upright in a refrigerator between 2°C and 8°C
- Never freeze the vial
- Keep it in the outer carton to protect it from light
- Use the vial within 60 days of first opening, and always check the expiry date before use
Additionally, always keep insulin, syringes and sharps out of sight and reach of children and other animals. Used needles should go straight into a proper sharps container and be returned to your vet or pharmacy for safe disposal.
Important Information
ProZinc should only be used for the pet named on the prescription, and always exactly as your vet advises. Because insulin lowers blood sugar, hypoglycaemia (low blood sugar) is a common effect of treatment; signs can include increased hunger, anxiety, twitching, an unsteady or stumbling gait, and disorientation. If you notice these signs, or more serious signs such as weakness, collapse or seizures, offer food or a glucose source if your pet can safely eat, and contact your vet urgently for further advice.
