Learn More About Dosing & Administration
Administration information is useful to share with clients and hospital staff to ensure the proper amount of insulin is given.
Vetsulin®(porcine insulin zinc suspension)
Vetsulin® 10 mL vials and 2.7 mL cartridges should be shaken thoroughly until a homogeneous, uniformly milky suspension is obtained.Syringe Administration Instructions
Taking the proper steps to prepare VetPen® is critically important and must be done before each injection.VetPen® Administration Instructions
In dogs, the labeled starting Vetsulin dose is 0.5 IU insulin/kg of body weight. This dose should be given once daily concurrently with or right after a meal.
Veterinarians should reevaluate canine patients at appropriate intervals and adjust the dose based on clinical signs, urinalysis results, and glucose curve values until adequate glycemic control has been attained.
Achieving Effective Glycemic Control
The goals of managing canine diabetes mellitus include:
- Controlling the clinical signs of hyperglycemia (polyuria, polydipsia)
- Avoiding hypoglycemia
- Obtaining blood glucose curve values in the desired range:*
- Dogs: 100–250 mg/dL over the course of the day, with a nadir between 100–150 mg/dL
*In the US clinical study, glycemic control was considered adequate if an acceptable blood glucose curve was achieved (ie, reduction in hyperglycemia and a nadir of 60–160 mg/dL), however, the Technical Services department believes that a nadir below 100 mg/dL in dogs may warrant a decrease in the dose.
Further adjustments in dosage may be necessary with changes in the dog’s diet, body weight, medications, or if the dog develops concurrent infection, inflammation, or other medical disorder.
Hypoglycemia is a major concern. To help avoid overdosing, particularly during initial stabilization:
- The dog’s body weight should be rounded down to the nearest whole kilogram.
- The calculated dose of insulin should be rounded down to the nearest whole unit.
- If the initial insulin duration of activity proves to be inadequate, begin twice-daily therapy.
- If twice-daily treatment is initiated, each of the 2 doses should be 25% less than the once-daily dose of Vetsulin® required to attain an acceptable nadir.
- For example, a 20-kg dog recieving 10 IU of Vetsulin once daily would be transitioned to 7 IU of Vetsulin administered twice daily. See product label for more information.

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.
