How long can the Caninsulin vial be kept after opening?
Caninsulin should be stored in a refrigerator and not frozen. It is usually advised that any pharmaceutical product should be disposed of around one month after opening. The Caninsulin label stated that the product should be used for either 28 days or 42 days after first opening, depending on the country. This is based on studies that were carried out looked at Caninsulin use for up to 42 days after first opening. Most of the authorities that regulate medicines do not allow product labels that permit the use of sterile products for more than 28 days after first opening, hence the discrepancy between countries.
