PROZINC in Dogs

Once-daily dosing can be a reality for the majority of your canine diabetic patients with PROZINC® (protamine zinc recombinant human insulin).1

Following injection, PROZINC works to safely maintain glycemic control all day with convenient, once-daily dosing for most of your canine patients.

Safety & Efficacy

PROZINC for dogs is backed by the largest U.S. canine diabetes study to date.

In this study that included over 200 diabetic patients, PROZINC demonstrated efficacy and control of clinical signs associated with diabetes mellitus in both naive and previously treated diabetic dogs.2

83.3% showed improvement in excessive thirst3

83.8% showed improvement in excessive urination3

72% achieved diabetic control2

The safety and effectiveness of PROZINC insulin in puppies and in breeding, pregnant and lactating dogs has not been evaluated.

Possible Side Effects of PROZINC

The most common adverse reactions were lethargy, anorexia, hypoglycemia, vomiting, seizures, shaking (dogs only), diarrhea, and ataxia. Many of the adverse reactions, such as lethargy, seizures, shaking (dogs only), and ataxia, are associated with hypoglycemia. Glucocorticoid and progestogen use should be avoided.

PROZINC is contraindicated during episodes of hypoglycemia and in animals sensitive to protamine zinc recombinant human insulin or any other ingredients in PROZINC. For more information, please see full prescribing information.
