Vetsulin is indicated for the control of hyperglycemia in dogs and cats with diabetes mellitus. It is commonly prescribed when diet and exercise alone are insufficient to manage blood sugar levels in diabetic pets.
Vetsulin contains porcine insulin zinc suspension, which is an intermediate-acting insulin. It works by facilitating the uptake of glucose into cells for energy, suppressing liver glucose production, and reducing blood glucose levels. The insulin typically begins working within 1-2 hours after injection.
Vetsulin must be prescribed and monitored by a veterinarian. Proper storage (refrigerated), consistent administration times, and regular blood glucose monitoring are essential. Side effects may include hypoglycemia if overdosed. Pet owners should be trained on proper injection technique and recognize signs of both high and low blood sugar.
