ProZinc® Vial for Feline Diabetes

This is a protamine zinc insulin used to control diabetes in cats. This page explains how it works, safe use, and storage, with US shipping from Canada. It also highlights ways to manage costs, even without insurance.

What ProZinc Is and How It Works

ProZinc® is a long-acting protamine zinc insulin approved for feline diabetes. It helps lower blood glucose by enabling cells to use circulating sugar for energy. Effects can last through a typical 12-hour cycle in many cats. The suspension should be gently mixed before each dose so the active ingredient is evenly dispersed.

ProZinc for cats vial is a veterinary formulation designed for consistent day-to-day use. Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing. The treatment is given by subcutaneous injection, usually alongside meals, to support steady glucose control across the day.

Who It’s For

This medicine is intended for cats diagnosed with diabetes mellitus, as confirmed by a veterinarian. It may be considered after diet and routine changes are planned. Cats with known hypersensitivity to any component should avoid it. Extra caution is necessary in underweight cats, those with concurrent illnesses, or those on medicines that affect glucose levels. Breeding, pregnant, or nursing queens require veterinary oversight.

Dosage and Usage

Veterinarians set the dose and schedule based on the cat’s weight, blood glucose data, and response over time. Caregivers typically give injections twice daily with meals. Use U-40 insulin syringes, not U-100 syringes, to ensure accurate measurement. Protamine zinc insulin for cats 10 mL should be administered subcutaneously as directed, rotating injection sites to reduce local irritation.

Gently roll the vial between the palms to resuspend the insulin. Do not shake. Inspect the solution; it should be uniformly milky after mixing, without clumps or strands. Clean the vial’s rubber stopper before each puncture. Do not reuse needles. Keep a written log of doses and observations to share with the veterinarian.

Strengths and Forms

This product is commonly supplied as ProZinc 40 U/mL 10 mL. It is a U-40 concentration and must be paired with U-40 syringes. Availability may vary by location and over time.

Missed Dose and Timing

If a dose is missed, guidance often favors giving the next scheduled dose rather than doubling up. ProZinc insulin for cats 10 mL should be given at consistent times, typically about 12 hours apart, to support a predictable glucose curve. When unsure what to do, contact the prescribing veterinarian. Watch for signs of low or high blood sugar if the routine changes.

Storage and Travel Basics

Store unopened and in-use vials in the refrigerator. Do not freeze. Protect from excessive light and heat. Keep the vial upright with the cap on when not in use. Many labels recommend discarding the vial a set number of days after first puncture; if timing is unclear, review the official label or ask the veterinarian. Keep insulin out of reach of children and pets.

You can travel with the vial if refrigerated storage is maintained. Use an insulated pouch with cool packs, and avoid placing insulin directly against ice. Carry supplies and copies of prescriptions in your hand luggage. If plans involve long trips, check with the veterinarian about monitoring. For orders, temperature-controlled handling when required is used by partner pharmacies.

Pen Handling and Sharps Disposal

This medicine is supplied as a vial for use with U-40 syringes. Place used syringes in an FDA-cleared sharps container. If a dedicated sharps container is not available, use a heavy-duty plastic household container with a tight-fitting, puncture-resistant lid. Follow local rules for disposal. Never recap a used needle, and keep sharps away from children.

Benefits

As a long-acting insulin, this therapy can support smoother daily glucose control when paired with diet and routine. The suspension is formulated for predictable kinetics in cats. A consistent twice-daily schedule may simplify caregiving routines. Care teams can adjust the dose over time based on clinical signs and glucose data.

Side Effects and Safety

• Low blood sugar: lethargy, weakness, unsteadiness, tremors, or seizures
• Gastrointestinal upset: decreased appetite, vomiting
• Behavior changes: unusual restlessness or sleepiness
• Injection site issues: mild swelling or discomfort

Serious hypoglycemia can be life-threatening. If severe signs occur, seek urgent veterinary care. Rarely, allergic reactions may present with swelling, hives, or breathing difficulty. Cats with concurrent endocrine disease, kidney issues, or infections may need closer monitoring. The veterinarian may recommend glucose curves or fructosamine tests to gauge control and safety.

Drug Interactions and Cautions

Medicines that can raise blood glucose, such as glucocorticoids or progestagens, may reduce insulin effectiveness. Others, including certain antibiotics, thyroid hormones, or diuretics, can alter insulin needs. Always tell the veterinarian about all medicines, supplements, and diet changes. Changes in activity, appetite, or concurrent illness can affect glucose and may prompt re-evaluation of the treatment plan.

What to Expect Over Time

Early in treatment, the care team often checks blood glucose and clinical signs to see how the cat responds. Improved thirst, urination, and energy may be observed as control improves. Some cats require dose adjustments and diet fine-tuning. Regular follow-up visits, home logs, and periodic lab tests help refine the plan. Consistency with feeding times, injection technique, and monitoring supports steady control.

Compare With Alternatives

Veterinarians may consider alternative insulins based on the cat’s response and history. Canine and feline veterinary insulin options differ in onset and duration. The Caninsulin Vial is another veterinary insulin used in many practices. For some cats, insulin glargine is discussed in clinical guidance; to learn more about that class, see Lantus Insulin. PZI insulin for cats vial is often selected when a longer duration is desired. Decisions should be guided by veterinary evaluation and monitoring data.

Pricing and Access

Canadian sourcing may offer favorable cash-pay options compared with some local quotes. To check ProZinc vial price and availability, view the product page for current details.

Availability and Substitutions

Supply can vary. If this item is temporarily unavailable, the prescriber may recommend a suitable alternative and provide new dosing instructions. Veterinary insulins are not interchangeable unit-for-unit, so any change should be supervised by the care team.

Patient Suitability and Cost-Saving Tips

This therapy suits many adult cats with diabetes when paired with diet and routine. It may be less suitable in cats with known hypersensitivity or certain concurrent illnesses unless closely monitored. To help manage overall spend, ask about multi-month fills when appropriate. Setting refill reminders can prevent gaps in therapy. The Pet Medications category can help compare options. You can also confirm origin details on product pages and filter for Canada when planning orders.

Questions to Ask Your Clinician

• Starting dose and timing: what schedule and meal plan are recommended?
• Monitoring plan: how to track glucose, and when to share logs?
• Diet: which food type and feeding routine fits the insulin profile?
• Hypoglycemia plan: which signs to watch for and what steps to take?
• Rechecks: when to schedule curves, fructosamine tests, or exams?
