Transitioning to Vetsulin® for Cats
Evaluate Reason for Switching Insulin Products
Is the cat adequately regulated on its current insulin or is one of the following factors causing problems:
- Is human error occurring?
- Is the insulin out of date, improperly stored, or misused?
- Does the cat have a concurrent disorder?
Identifying Any Resolvable Issues
After ruling out resolvable issues or possible concurrent disorders, simply discontinue use of the current insulin and begin administration of Vetsulin® (porcine insulin zinc suspension) at 1-2 IU per injection, twice daily.
Evaluate Your Patient Within 1 to 2 Weeks
Evaluate 1-2 weeks after starting Vetsulin, or earlier if clinical signs of hypoglycemia develop. Check factors including water consumption, urine frequency and volume, activity level, and weight changes.
If clinical signs of polyuria, polydipsia, and weight loss have not resolved, you may need to increase the cat’s dose by 0.5-1 IU per injection.

Important Safety Information:
Vetsulin® should not be used in dogs known to have a systemic allergy to pork or pork products. Vetsulin is contraindicated during periods of hypoglycemia. Keep out of reach of children. As with all insulin products, careful patient monitoring for hypoglycemia and hyperglycemia is essential to attain and maintain adequate glycemic control and prevent associated complications. Overdosage can result in profound hypoglycemia and death. The safety and effectiveness of Vetsulin in puppies, breeding, pregnant, and lactating dogs has not been evaluated. See package insert for full information regarding contraindications, warnings, and precautions.
