Product Overview

PROZINC® (protamine zinc recombinant human insulin) is the simple and reliable choice for diabetes control in dogs and cats. It is a veterinarian prescribed injectable insulin for cats and dogs. With just two daily doses a day in cats and once-a-day dosing in most dogs, delivered before or just after a meal, PROZINC insulin provides predictable glycemic control in pets with diabetes.1,2 A single PROZINC injection has an appropriate duration of activity (10-14 hrs) in cats and an extended duration of activity (16->24 hrs) in dogs.3

If your cat or dog has been diagnosed with diabetes mellitus, you understand the importance of regulating blood glucose and controlling clinical signs. With its appropriate duration of action in cats, and extended duration of action in dogs, PROZINC® insulin will provide glycemic control and help improve the quality of life of your cat or dog.1, 2

PROZINC® insulin should only be administered to the cat or dog for whom it was prescribed, and at the dosage and frequency for which it was prescribed. If you have any questions or concerns about the product or about diabetes mellitus, talk to your veterinarian. PROZINC® insulin requires refrigeration,2 as well as the use of U-40 syringes,2 which are sold separately.

ProZinc® (protamine zinc recombinant human insulin) is an injectable insulin for cats and insulin for dogs. PROZINC is an aqueous protamine zinc suspension of recombinant human insulin that is used to reduce hyperglycemia (high blood glucose or high blood sugar) and clinical signs associated with hyperglycemia in cats and dogs with diabetes mellitus.
For use in dogs and cats.
  • FDA-approved first-line treatment for diabetes in cats, is available for use in dogs.1
  • Extended duration of action of 16->24 hrs in dogs2
  • Reduces hyperglycemia and hyperglycemia-associated clinical signs in both cats and dogs with diabetes mellitus 3,4
  • Administered with pet-appropriate U-40 syringes4 (sold separately) to ensure accurate dosing and to minimize error
  • PROZINC® (protamine zinc recombinant human insulin) has been rigorously tested for safety and efficacy in cats and dogs3
PROZINC® (protamine zinc recombinant human insulin) is an injectable insulin for cats and dogs. PROZINC® is an aqueous suspension of protamine zinc recombinant human insulin that is indicated to reduce hyperglycemia (high blood glucose or high blood sugar) and clinical signs associated with hyperglycemia in cats and dogs with diabetes mellitus.1, 2 PROZINC® works by helping your pet move all-important glucose from the bloodstream into the cells. Cats and dogs with diabetes mellitus don’t produce enough of their own naturally produced insulin, or their own insulin doesn’t work properly, and this causes glucose to build up in their blood, leading to health problems. PROZINC® becomes the essential replacement for diabetics to get their appropriate source of daily insulin.
Cats and dogs presenting with severe ketoacidosis, anorexia, lethargy, and/or vomiting should be stabilized with short-acting insulin and appropriate supportive therapy until their condition is stabilized. As with all insulin products, careful patient monitoring for hypoglycemia and hyperglycemia is essential to attain and maintain adequate glycemic control and to prevent associated complications. Overdose can result in profound hypoglycemia and death. Glucocorticoids, progestogens, and certain endocrinopathies can have an antagonistic effect on insulin activity. Glucocorticoid and progestogen use should be avoided. The safety and effectiveness of PROZINC® insulin in breeding, pregnant, and lactating cats and dogs has not been evaluated. The safety and effectiveness of PROZINC® insulin in kittens and puppies has not been evaluated.
protamine zinc recombinant human insulin
Immediately contact your closest emergency animal hospital.
PROZINC® (protamine zinc recombinant human insulin) is for use in cats and dogs only. Keep out of the reach of children. Avoid contact with eyes. In case of contact, immediately flush eyes with running water for at least 15 minutes. Accidental injection may cause hypoglycemia. In case of accidental injection, seek medical attention immediately. Exposure to product may induce a local or systemic allergic reaction in sensitized individuals. As with all insulin products, careful patient monitoring for hypoglycemia and hyperglycemia is essential to attain and maintain adequate glycemic control and to prevent associated complications. Overdose can result in profound hypoglycemia and death. 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. The safety and effectiveness of PROZINC® insulin in puppies, kittens, or breeding, pregnant, and lactating animals has not been evaluated. PROZINC® insulin is contraindicated during episodes of hypoglycemia and in animals sensitive to protamine zinc recombinant human insulin or any other ingredients in PROZINC® insulin. For additional information, please see full prescribing information.
PROZINC® (protamine zinc recombinant human insulin) is available as PROZINC® 40 units per mL, 10 mL and 20 mL vials and PROZINC® Diabetes Care Kit Syringe-Dispenser/Sharps Container 100 0.3 cc or 1.0 cc U-40 Syringes.
Boehringer Ingelheim
This product is most effective when given during meals or immediately thereafter. It is suggested that injections are administered at a set time every day for the sake of managing steady glucose levels. NOTE* Contains U-40 insulin: Be sure to administer with according U-40 syringe.

USE OF A SYRINGE OTHER THAN A U-40 SYRINGE WILL RESULT IN INCORRECT DOSING. FOR SUBCUTANEOUS INJECTION ONLY. DO NOT SHAKE OR AGITATE THE VIAL. PROZINC® insulin requires refrigeration at all times.

PROZINC® (protamine zinc recombinant human insulin) should be mixed by gently rolling the vial prior to withdrawing each dose from the vial. Once mixed, PROZINC® insulin suspension has a white, cloudy appearance. Clumps or visible white particles can form in insulin suspensions: do not use the product if clumps or visible white particles persist after gently rolling the vial. Using a U-40 insulin syringe, the injection should be administered subcutaneously on the back of the neck or on the side of the cat or dog.

FOR CATS:

The initial recommended PROZINC® dose is 0.1 – 0.3 IU insulin/pound of body weight (0.2 – 0.7 IU/kg) every 12 hours. The dose should be given concurrently with or right after a meal. The veterinarian should re-evaluate the cat at appropriate intervals and adjust the dose based on both clinical signs and glucose nadirs until adequate glycemic control has been attained. In the effectiveness field study, glycemic control was considered adequate if the glucose nadir from a 9-hour blood glucose curve was between 80 and 150 mg/dL and clinical signs of hyperglycemia such as polyuria, polydipsia, and weight loss were improved.

Further adjustments in the dosage may be necessary with changes in the cat’s diet, body weight, or concomitant medication, or if the cat develops concurrent infection, inflammation, neoplasia, or an additional endocrine or other medical disorder.

FOR DOGS:

Starting dose: The recommended starting dose for PROZINC® is 0.2-0.5 IU insulin/pound of body weight (0.5- 1.0 IU/kg) once daily. The recommended starting dose for naïve dogs is the lower end of the dose range. The recommended starting dose for dogs with poorly controlled diabetes mellitus and transitioning from another insulin product is the mid to higher end of the dose range based on the veterinarian’s experience with the dog’s medical history and previous insulin dose. When transitioning from another insulin, the dog’s blood glucose and general condition should be closely monitored. When transitioning from another insulin, PROZINC® insulin should be started once daily, regardless of the frequency of prior insulin use.

The dose should be given concurrently with or right after a meal. The veterinarian should re-evaluate the dog at appropriate intervals and adjust the dose and frequency based on both clinical signs and laboratory test results (the blood glucose curve values and shape, nadir, and fructosamine) until adequate glycemic control has been attained. In the effectiveness field study, glycemic control was considered adequate if the glucose nadir from a 9-hour blood glucose curve was between 80 and 125 mg/dL, the maximum blood glucose was < 300 mg/dL, and clinical signs of hyperglycemia such as polyuria, polydipsia, or weight loss were improved.

Changing to twice daily dosing: Twice daily dosing should be considered if the duration of insulin action is determined to be inadequate with once daily dosing. Use caution when adjusting from once daily to twice daily dosing because PROZINC® insulin may have prolonged duration of action in some dogs (see Clinical Pharmacology). The veterinarian should closely monitor the duration of action using blood glucose curves to avoid the increased risk of hypoglycemia. If twice daily dosing is initiated, the two doses should each be approximately 25% less than the once daily dose required to attain an acceptable glucose nadir. For example, if a dog receiving 10 units of PROZINC® insulin once daily has an acceptable nadir but inadequate duration of activity, the dose should be changed to 7 units twice daily (round down to the nearest whole unit).

Further adjustments in the dosage may be necessary with changes in the dog’s diet, body weight, or concomitant medication, or if the dog develops concurrent infection, inflammation, neoplasia, or an additional endocrine or other medical disorder.

Gloria G Verified Purchase

I trust Allivet to get my cat’s insulin to us in a safe and timely manner. We have used them for years and the shipment always arrives quick and in great condition. Insulin has to stay cool before, during and after transit and they package In a way that makes this possible. In fact, the ice packs are barely even starting to thaw when we open the package. I definitely recommend Allivet for your pets needs because they truly care!

My review isn't so much about the product...tho' it is what my cat needs and he's doing well on it. This is what I want to share: last week I was expecting a (cold) shipment of this insulin. The carrier notified me that the package would be delayed a day, and when it arrived the contents were no longer cold. I emailed Allivet to see if the insulin would be compromised due to lack of ice. They replied that to be on the safe side, they would send out another vial. By the time I read that reply, the order was already enroute. It arrived nice and cold. I was just so impressed with the customer service! Thanks!

This was my 2nd order, and I plan to stick with Allivet due to their reliable, prompt service and lower price. Both times, Allivet jumped on my order and shipped immediately. Because Insulin is temperature sensitive - I was pleased to see it arrived the very next day, still cold, and packed in quality cold pack boxes. Can't beat that kind of service!

Susan M Verified Purchase

When you insert the syringe in the top of the vile, the rubber top is kind of hard to get the syringe into it, so you have to be really careful not to bend the syringe. Other than that its ok.

Vicky P Verified Purchase

Recently diagnosed kitty requires this drug. My first bottle was running out and I thought it would be easy to just pick up but was not available in local pharmacies. Thankfully, I was able to place an order (as a new customer) on Saturday, and had the new bottle on hand on Wed before mine ran out. They kept me appraised of the prescription verification process and shipping status throughout, so I didn't worry that I wouldn't get it in time. The overnight S&H was pricy, but arrived cold and in good shape. Good job, Allivet!

Barb J Verified Purchase

I've purchased insulin for Grey from my veterinarian since he was diagnosed almost 3 years ago. The first bottle was $130 but since then the cost has increased quite a bit. I searched the web and found several places that sold ProZinc at a variety of prices. Allivet was one of the lowest prices I found and had the best reviews so I decided to trust Allivet to provide my insulin for Grey and am confident they won't let me down!This is my first purchase with them but I'm sure I will make more purchases if they are as dependable and consumer friendly as they seem to be!

Bernadette L Verified Purchase

My other kitty 3 years ago used human insulin, and it worked well, but the ProZinc has been wonderful for TT. Excellent product and easy to regulate with no issues. After 4 months she is still doing so well. Her weight is up to 7 pounds after being at 5 ans her blood sugar is stable. she is 20 so her being this happy and stable again means the world to us. Allivet is wonderful as well. Their customer service is first rate and do everything to accommodate their customer. The insulin was amazing packed in cold packs and arrived in 24 hours, ready to go. They even found a way to pack my needles in the same order which was perfect!!! Thank you. Bernadette L.

Rachel P Verified Purchase

The insulin was fine, though the ice had just about melted when it arrived late in the day. What really bugged me was the WEEKS of back and forths implying my vet wasn't responding.. and Allivet not having good communication with me about why my package wasn't showing up... let alone them calling the wrong number and using the wrong fax for the vet on multiple occasions. The whole idea of confirming by fax is archaic. Get with the times and develop better communications protocols, please!
