ProZinc® Vial for Diabetic Cats

ProZinc is a veterinary insulin used to manage diabetes in cats. This page explains how the medicine works, safe handling, and key storage tips. You can arrange US delivery from Canada and review options if you pay without insurance.

What ProZinc Is and How It Works

ProZinc® is protamine zinc insulin formulated for feline diabetes. The preparation is long-acting and intended for subcutaneous use after meals. As a suspension, it should be gently rolled before drawing a dose to resuspend crystals.

The veterinary ProZinc insulin 10 mL vial supports steady glucose control when used as directed. It lowers blood sugar by enabling cellular uptake of glucose and reducing hepatic output. Effects can vary among cats, so your prescriber will individualize the plan.

Who It’s For

This medicine is indicated for the management of diabetes mellitus in cats diagnosed by a veterinarian. It is not for treatment of acute diabetic emergencies. Cats with known hypersensitivity to insulin components should avoid it. Kittens, pregnant, or nursing cats require cautious assessment and close supervision. Use only if a professional confirms the diagnosis and provides a dosing plan.

Dosage and Usage

This treatment is given by subcutaneous injection, typically with meals. Use syringes that match the vial’s labeled concentration, and follow your prescriber’s instructions closely. Roll the vial between your hands to mix; do not shake. Inspect the suspension before each use and do not use if you see clumps, discoloration, or particles that do not disperse with gentle rolling.

Give injections in a rotating pattern over recommended sites to reduce local irritation. Use a new sterile needle for every injection. Never share syringes. If your prescriber supplies a glucose monitoring plan, follow it consistently and record results. For background on dose concepts, see the Insulin Dosage Chart and device tips in Pen vs Syringe.

Strengths and Forms

This protamine zinc insulin 10 mL vial is a sterile suspension for injection. The labeled concentration is U-40 (40 units per mL). Availability may vary by pharmacy and region.

Missed Dose and Timing

If a dose is missed, do not double the next dose. Give the next scheduled injection as directed unless your prescriber instructs otherwise. Do not administer if your cat is not eating, is vomiting, or appears unwell; contact the clinic for guidance. Keep a note of any missed doses and share the details during follow-up.

Storage and Travel Basics

Store unopened and in-use vials according to the product label, typically refrigerated and protected from light. Do not freeze. Keep the vial upright with the cap on when not in use. Discard if the product has been frozen, overheated, contaminated, or past the in-use period on the label. Keep out of reach of children and pets.

For travel, carry the vial in an insulated case with reusable cold packs to maintain stable conditions. Do not place the vial directly against ice. Pack extra needles, a backup syringe supply, and a copy of your prescription and clinic contact information. For flights, keep the vial in your personal item and declare supplies if asked. Our pharmacies use temperature-controlled handling when required.

Benefits

This medicine belongs to the protamine zinc class, which can provide sustained insulin action suitable for cats. The profile may support two daily injections aligned with feeding. The vial format allows precise dosing with matched syringes. Many caregivers find the routine easier once a consistent schedule, rotation of injection sites, and monitoring plan are established. PZI insulin 10 mL vial may also help veterinarians fine-tune care during follow-ups.

Side Effects and Safety

• Low energy or unusual sleepiness
• Changes in thirst or urination patterns during initial adjustment
• Decreased appetite or gastrointestinal upset
• Mild redness, swelling, or discomfort at the injection site
• Restlessness or behavioral changes

Serious effects can occur, including hypoglycemia with signs such as weakness, tremors, disorientation, seizures, or collapse. High blood sugar with ketones (diabetic ketoacidosis) is a veterinary emergency. Allergic reactions and injection site infection are uncommon but possible. Seek urgent veterinary care if severe signs appear, or if your cat stops eating or is vomiting.

Drug Interactions and Cautions

Other medicines can affect glucose control. Corticosteroids, progestogens, certain diuretics, thyroid agents, and some antibiotics may alter insulin requirements. Beta blockers can mask warning signs of low blood sugar. Alcohol-containing products and appetite stimulants may also influence glucose levels. Do not mix this insulin with other insulins in the same syringe. Inform your veterinarian about all prescriptions, over-the-counter items, supplements, and recent diet changes.

What to Expect Over Time

Your veterinarian may adjust the care plan after reviewing glucose readings, clinical signs, and feeding patterns. Many cats need several checks to reach a stable regimen. Consistent timing of meals, injections, and monitoring often improves predictability. Keep a log of doses, food intake, and behavior changes to share during rechecks. If a transition between insulin types is needed, the prescriber will provide a stepwise plan to minimize variability.

Compare With Alternatives

Veterinarians may consider other insulin preparations for feline diabetes. Two commonly used options are Caninsulin® Vial and Caninsulin® Cartridges. These contain porcine lente insulin and have different pharmacologic characteristics and device formats. Your clinic can explain whether a lente profile or a vial versus cartridge approach fits your cat’s needs.

Availability and Substitutions

Supply can vary by season and manufacturer distribution. If the requested vial is temporarily unavailable, a prescriber may recommend an alternative insulin profile for continuity. If you need a ProZinc refill 10 mL vial, request it ahead to allow time for verification. Do not switch between insulin types or concentrations without veterinary guidance.

Patient Suitability and Cost-Saving Tips

Cats with stable eating habits and a predictable routine often do well on a structured insulin plan. Cats with frequent vomiting, severe concurrent illness, or unpredictable food intake may need closer monitoring or hospital-based adjustments. For costs, consider multi-month quantities when appropriate, set refill reminders, and coordinate orders with scheduled rechecks. Keeping a steady diet, dose timing, and injection technique can reduce waste from discarded or mishandled vials.

Questions to Ask Your Clinician

• What monitoring schedule and targets should we use at home?
• Which injection sites are best for my cat, and how should I rotate them?
• How should I handle days with poor appetite or illness?
• Which glucose signs require an immediate clinic call?
• What diet and feeding timing best support this insulin’s action?
• How often should we schedule rechecks and glucose curves?
