PRODUCT INFORMATION

Supply Update: Caninsulin VetPen Cartridges are currently affected by a manufacturer supply issue from MSD. There is currently no confirmed date for the next delivery.
If your pet requires ongoing treatment, please contact your veterinary surgeon to discuss suitable alternatives or interim management.


Caninsulin 40 IU/ml contains porcine insulin and is indicated for the treatment of diabetes mellitus in dogs and cats.

These 2.7ml cartridges are specifically designed for use with the Caninsulin VetPen device and allow accurate, controlled dose delivery in animals prescribed insulin therapy.

Caninsulin may be prescribed for diabetic dogs and cats to regulate blood glucose concentrations and improve associated clinical signs including polyuria, polydipsia, weight loss and lethargy.

This product is a prescription-only veterinary medicine (POM-V).

Dosage, frequency of administration and delivery system are determined by the prescribing veterinary surgeon and provided on the dispensing label.

These cartridges must only be used with a compatible Caninsulin VetPen and appropriate pen needles. They are not suitable for use with standard insulin syringes.

Further information, including contraindications and potential side effects, can be found in the product data sheet available here.
