Canine Diabetes
   Frequently Asked Questions

Q.  Can canine insulin go bad?

A.  Yes. Canine insulin is usually derived from domestic cattle or pigs and contains a live culture. It should be kept refrigerated between 2 degrees and 8 degrees Celsius and has a life-span of 28 days from the time the phial is opened.

The insulin culture is suspended in a solution to help preserve the culture, which is why mixing gently prior to loading the syringe is so important.

Although it is possible the insulin can still be used after 28 days, the effectiveness decreases over time and ideally a fresh phial used after 28 days.
