Prozinc® Vial for Feline Diabetes

What Prozinc Is and How It Works

Prozinc® 10 mL vial is a U-40 protamine zinc insulin for cats with diabetes mellitus. Ships from Canada to US so you can manage pet insulin refills without insurance using Canadian pricing. This medicine lowers blood glucose by helping tissues absorb glucose and by reducing liver glucose output.

The treatment contains protamine and zinc, which slow insulin release after subcutaneous injection. It is considered intermediate-acting in cats. Your veterinarian will tailor a plan that includes diet, monitoring, and dose adjustments based on clinical signs and glucose testing.

Who It’s For

Prozinc vial for feline diabetes is indicated for cats diagnosed with diabetes mellitus. It may also be appropriate for some dogs when a veterinarian determines it fits the care plan.

Do not use in pets with a known hypersensitivity to insulin components. Pets with severe hypoglycemia, suspected diabetic ketoacidosis, or concurrent serious illness require urgent veterinary care and individualized management.

Dosage and Usage

Prozinc U40 insulin vial is used for subcutaneous injection as directed by your veterinarian. In many cats, dosing is given twice daily with meals. The regimen is individualized from clinical signs, blood glucose curves, and fructosamine results.

Gently roll the vial between your hands to resuspend; do not shake vigorously. Use only U-40 insulin syringes to draw the correct volume. Rotate injection sites along the flanks or scruff to reduce local irritation. Feed consistent meals and keep a regular dosing schedule.

Monitor for changes in thirst, urination, appetite, weight, and activity. Your veterinarian may advise periodic home glucose checks or clinic curves to guide adjustments. Never change the dose or schedule without veterinary guidance.

Strengths and Forms

Prozinc PZI 40 U/mL vial is supplied as a 10 mL multiple-dose vial. The formulation is protamine zinc insulin (PZI) at U-40 concentration, intended for use with matching U-40 syringes.

Availability can vary by location and supply. Always confirm the presentation and concentration on the label before use.

Missed Dose and Timing

If you miss a scheduled injection, contact your veterinarian for guidance if you are unsure what to do. In general, avoid giving two full doses close together. Resume the regular schedule at the next planned time unless instructed otherwise.

If a pet vomits, skips a meal, or seems unwell around dosing time, consult your veterinarian before giving insulin. Keep written notes on doses, meals, and signs to support clinical decisions.

Storage and Travel Basics

Store unopened and in-use vials under refrigeration. Do not freeze, and protect from direct heat and light. Discard the vial if it has been frozen, overheated, changes appearance, or reaches the in-use discard date specified on the label or by your veterinarian.

After first puncture, most labels advise using the contents within a defined period; check the current package insert for the recommended timeframe. Keep the cap on when not drawing a dose, and keep out of reach of children and pets.

When traveling, carry the vial in an insulated container with cool packs to maintain a stable temperature. Keep the insulin with you in a carry-on rather than in checked baggage. Bring your prescription, dosing plan, and a written note from your veterinarian to ease travel. For extra protection against breakage in bags, consider a dedicated accessory such as the Vial Safe Protector.

Pen Handling and Sharps Disposal

This medicine is supplied as a vial for syringes. Use new, sterile U-40 syringes and needles for every injection. Never share syringes between pets.

Dispose of used needles in an approved sharps container. Follow local rules for disposal; your veterinarian or pharmacy can help with options. If needed, a vial protector can help reduce accidental drops during handling.

Benefits

This insulin helps control high blood sugar and associated signs such as excessive thirst, frequent urination, weight loss, and lethargy. The U-40 concentration supports small, precise dose volumes suited to feline dosing.

A consistent daily routine with this treatment can support stable glucose patterns. Regular monitoring and veterinary oversight can help maintain control over time.

Side Effects and Safety

• Low blood sugar: shakiness, ataxia, disorientation, lethargy, seizures
• Digestive changes: reduced appetite, vomiting
• Behavioral changes: restlessness or unusual quietness
• Injection site reactions: mild redness, swelling, or discomfort

Severe hypoglycemia is an emergency; rub a small amount of corn syrup or honey on the gums if instructed by your veterinarian and seek immediate care. Uncontrolled diabetes can lead to dehydration, ketones, and diabetic ketoacidosis, which requires urgent treatment. Report persistent vomiting, rapid breathing, collapse, or other alarming signs promptly.

Pets on insulin and sulfonylureas can have an increased risk of low blood sugar; careful monitoring is advised. Always follow veterinary guidance for diet and dosing.

Drug Interactions and Cautions

Certain medications can alter insulin needs. Examples include corticosteroids, progestins, diuretics, sympathomimetics, thyroid medications, and some antibiotics. Beta blockers may mask fast heart rate during hypoglycemia. Discuss all medicines, supplements, and recent changes with your veterinarian.

Stress, infection, dental disease, pancreatitis, and diet changes can affect blood sugar control. Use during pregnancy or lactation only if the expected benefit outweighs potential risks. Keep a consistent feeding schedule and carbohydrate content to avoid unexpected swings.

What to Expect Over Time

Glycemic control often improves stepwise as your veterinarian refines the dose and timing. You may notice better energy, steadier appetite, and improved weight over time with stable control.

Periodic glucose curves or fructosamine tests can help track trends. Keeping a daily log of doses, meals, water intake, and behavior supports long-term management. If patterns shift, your veterinarian may adjust the plan.

Compare With Alternatives

Veterinarians sometimes consider other veterinary insulins based on the pet’s response, comorbidities, and dosing needs. For example, Caninsulin® Vial is an alternative veterinary insulin, and some patients may benefit from a cartridge format such as Caninsulin® Cartridges. Long-acting human analogs may be considered in select cases under veterinary supervision.

Availability and Substitutions

Supply can vary. If this item is unavailable, your veterinarian may recommend a suitable alternative insulin or a dosage form that matches your pet’s needs. Do not switch products or concentrations without veterinary guidance.

Patient Suitability and Cost-Saving Tips

This therapy may be appropriate for adult cats with confirmed diabetes mellitus who can tolerate injections and regular monitoring. It may not suit pets with frequent hypoglycemic episodes or those unable to maintain a consistent feeding schedule.

Ask your veterinarian if multi-month prescriptions are appropriate, which can reduce refill frequency and help reduce overall costs. Set calendar reminders for refills and glucose checks. Ordering syringes and supplies with the insulin may reduce separate trips and help maintain adherence.
