ProZinc Insulin For Cats 40iu/ml 10ml Vial

ProZinc Insulin is a protamine zinc insulin created specifically with cats in mind.

ProZinc works quickly and effectively to regulate blood glucose levels.

It is available in single vials of 10ml.

Protamine zinc insulin formulations are typically effective for 10-14 hours in cats.

Prozinc needs to be kept below 8°C to ensure its efficacy. During periods of hot weather dispatches may be temporarily delayed. Do not freeze.

In addition the manufacturer recommends that all Prozinc is stored vertically. Again this is functionally impossible to guarantee or police during transit.

We are unable to deliver to Northern Ireland.

This is a prescription item and will be sent once a valid prescription is received.

This item will only be dispatched Monday-Thursday.

There is a £5.99 charge for delivery on this product due to it being temperature controlled. We send your medicine via courier with extra packaging to make sure your item arrives to you in the best condition.We do NOT ship Prozinc during prolonged periods of hot weather. However, even with these temperature control safeguards in place it is impossible to guarantee that the product will stay at the manufacturer's recommended temperature of 8°C or below during the dispatch process - as we have no control how it is stored after being collected from us and before it gets to you.

Separate ProZinc syringes are available for sale separately. We would recommend that only these are used as the dosages are specifically designed for ProZinc.


If you see the "prescription required" sign next to an item you’d like to order, it means the item can only be issued with a prescription. While you can add these items to your shopping cart and pay for them along with other non-prescription products, we can’t dispatch them until we’ve received a prescription.
