Caninsulin 40 IU/ml Suspension for Injection – Adverse events

Increase in suspected adverse event reports following use of Caninsulin 40 IU/ml Suspension for Injection.

We wish to raise awareness of an increase in suspected adverse event reports following use of Caninsulin 40 IU/ml Suspension for Injection in the UK.

The reported adverse events most commonly include pain at the injection site and immediate pain upon injection, which may manifest as vocalisation, avoidance, or defensive behaviours. We have also noted a relative increase in lack of efficacy reports.

Adverse event reports received may include reports where more than one product was used, the product was used off-label and/or, where, on further evaluation, it is considered that there is no causal association between the product and event.

In order to comply with the British Pharmacopeia, there has been a recent change to the product formulation, with the preservative ‘methyl parahydroxybenzoate’ replaced by ‘Metacresol 0.3 % w/v’. No changes have been made to the insulin content of the product.

If reporting an adverse event following the use of this product, the VMD requests that as much detail is provided as possible, especially the batch number and colour of the cap of the product (blue or purple tops for vials, silver or gold tops for cartridges) if this information is available.

We are working with the company responsible for the product (MSD Animal Health UK Limited) to investigate this finding and are closely monitoring reports.
