What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.

    • Description

      ProZinc is a recombinant insulin used for pet diabetes treatment in dogs and cats to counter hyperglycemia by reducing blood sugar levels. With one daily injection it works to safely maintain the animal’s lower blood glucose levels and works to overcome the insulin deficiency or insulin resistance resulting from diabetes mellitus. The recombinant human insulin is fortified with zinc that controls the rate at which insulin is released in the bloodstream and protamine that delays absorption. With this medication the delivery of purified insulin into the bloodstream is controlled and extended.


      ProZinc injections should be given just before or just after a meal and injections should be given at the same time each day.


      Gently roll the ProZinc insulin vial in your hands for 10 seconds after you remove it from the refrigerator.

      Remove caps from plunger and needle.

      Pull back the plunger on the syringe to the number that corresponds with the number of units your veterinarian has advised you administer to your pet with each injection.

      Inject the needle into the top of the ProZinc vial and press the needle down to inject the necessary amount of air into the bottle.

      Flip the vial upside down while making sure the needle stays submerged in the solution.

      Now pull back on the plunger and go 2 or 3 units past the number recommended by your veterinarian.

      Tap the side of the syringe to eliminate any air bubbles in it.

      Push the plunger back in to the exact number of units recommended by your vet.

      Remove the needle from the vial.


      Alternate injection sites on skin near the pet's shoulders.

      Once a sport is chosen, gently pull up a fold of skin and inject the needle straight in.

      Pull plunger on syringe back slightly and confirm there is no blood in the syringe. If there is blood, pull the needle out and begin this whole administration process again.

      If no blood is seen, gently push the plunger in as far as necessary to administer the entire dose and then remove the needle.

      Dispose of the needle responsibly in a Sharps container.


      The active ingredient in ProZinc is Protamine Zinc Recombinant Human Insulin.


      ProZinc is to be injected with a U-40 syringe only. Using any other type of syringe could result in incorrect dosing and serious harm or even death occurring to the pet.

      Never dilute ProZinc

      Pet insulin should be refrigerated (do not freeze) and kept out of direct light.

      Vials that are exposed to high heat or frozen must be discarded.

      Contents of vial not administered should be discarded after 42 days of vial first being punctured.

      It is important that you pet eats before you administer ProZinc.

      Syringes should be disposed of properly in a Sharps container.


      There is the possibility of negative drug interactions between ProZinc and other Rx medications, including prescription drugs for pets classified as antimicrobials, antivirals, antifungals, antihistamines, analgesics, anesthetics/tranquilizers, diuretics, bronchodilators, corticosteroids (cats), NSAIDs, thyroid hormone supplementation, hyperthyroid medication (methimazole), internal and external parasiticides, anti-emetics, dermatological topical treatments and oral supplements, and ophthalmic preparations containing antimicrobials and anti-inflammatory medications.

      Vaccines may also present interaction risks. Tell your veterinarian of all medications your pet is currently taking before getting prescription and proceeding to buy ProZinc.

      Side Effects

      ProZinc side effects are a possibility, and some pets may experience vomiting, hypoglycemia, anorexia, poor appetite, diarrhea, lethargy, cystitis, hematuria, and weakness. If these side effects are seen it may be best to discontinue use until you are able to meet with a veterinarian and discuss other pet insulin options or alternatives with treating pet diabetes.
