How to Administer

Caninsulin should be administered once or twice daily. Always make sure to alternate the injection site on a daily basis to avoid irritation. Before each use, invert the vial a few times until a homogenous suspension is obtained. A 40 IU/ml insulin syringe should be used.

The cartridge should be used with VetPen. Within the package will be a leaflet with detailed instruction for use to be followed.

If the needle is removed from the skin too early, sometimes small drops of insulin may leak from the needle, this can mean an incomplete dosing. If this occurs, do not attempt to re-dose. Wait and give your pet its usual dose at the next injection.
