Caninsulin® Vial for Dogs and Cats

These vials contain a porcine insulin zinc suspension for dogs and cats with diabetes. It helps lower high blood sugar when used as directed. US delivery from Canada makes it easier to request refills, even without insurance.

What Caninsulin Is and How It Works

Caninsulin® is a veterinary porcine insulin zinc suspension indicated to control hyperglycemia in diabetic dogs and cats. It acts by enabling cellular glucose uptake and reducing hepatic glucose output. The treatment is intermediate in action and is given by subcutaneous injection with meals, as directed by your veterinarian.

Who It’s For

This medicine is used to manage diabetes mellitus in dogs and cats diagnosed by a veterinarian. Pets with current hypoglycemia should not receive an insulin dose. Do not use in animals with a known allergy to pork-derived insulin or formulation components. The Caninsulin insulin for dogs vial may be prescribed to stabilize chronic hyperglycemia in canine patients. Cats can also be treated when the prescriber determines this class is appropriate. Use caution in pregnant or breeding animals and in pets with significant liver or kidney disease.

Dosage and Usage

Your veterinarian will set the starting dose and schedule, and may adjust it based on blood glucose curves and clinical signs. Insulin is typically injected under the skin once or twice daily with food. Before each injection, gently roll the vial between your hands until the suspension appears uniformly milky; do not shake vigorously. Use a new sterile syringe for every dose. Clean the stopper, draw the exact volume, expel air bubbles, and inject into the recommended site. Rotate injection sites to reduce local irritation. Always follow your prescriber’s instructions and the product label.

Practice the injection technique during your first training visit. Keep a written log that records time, dose, feeding, and any observed signs. Give insulin at consistent times to match your feeding plan. If multiple caregivers are involved, use a checklist to prevent duplicate doses. Contact your clinic before changing diet, treats, or activity level, because these can affect insulin needs.

Strengths and Forms

The vial presentation is a multi‑dose bottle intended for repeated withdrawals using syringes. Availability may vary by pharmacy and region.

Commonly supplied strength and presentation includes porcine insulin suspension 40 IU/mL 10 mL. Cartridges for compatible pens exist in some markets and may be offered separately.

Missed Dose and Timing

If a dose is missed, contact your veterinarian for advice. In general, do not double the next dose. If it is close to the next scheduled injection, skip the missed dose and resume the regular plan. Watch for signs of high or low blood sugar, such as increased thirst, lethargy, tremors, or unsteadiness, and seek veterinary guidance promptly if you are concerned.

Storage and Travel Basics

Store unopened vials refrigerated at 2 to 8°C. Do not freeze. Keep the bottle upright and protect it from direct light. After first puncture, follow the in‑use time on the label and discard any remaining liquid when that period ends. Avoid excessive heat, and keep all insulin out of reach of children and pets. For travel, carry the vial in an insulated pouch with cool packs and avoid placing it next to ice. Bring your prescription or a note from your veterinarian when flying. Our service uses temperature-controlled handling when required.

During road trips, use a cooler that maintains refrigerator temperatures and keep spare vials separated from active stock. When flying, carry insulin in your hand luggage and avoid checked baggage. Do not expose the vial to direct sunlight on dashboards or window seats. Pack extra syringes, a copy of dosing instructions, and contact information for your clinic in case plans change.

Syringe Handling and Sharps Disposal

Use only U‑40 insulin syringes with this product; do not substitute U‑100 syringes. This prevents dosing errors. Confirm the units and markings before each injection. Never reuse needles. Place used syringes and needles in a puncture‑resistant sharps container immediately after use. When full, follow local rules for disposal through your pharmacy or municipal program.

Benefits

This therapy helps reduce excessive thirst, urination, and weight loss associated with uncontrolled diabetes. It allows more flexible feeding plans under veterinary guidance. Many caregivers find the vial format practical for dosing at home. Consistent use with diet and monitoring can improve quality of life for pets living with diabetes.

Because porcine insulin is structurally similar to canine insulin, some dogs may respond predictably to this class when dosing and diet remain stable. The vial format also supports fine dose adjustments using appropriate syringes, which can aid day‑to‑day control.

Side Effects and Safety

• Low blood sugar: weakness, tremors, disorientation, seizures
• Injection site reactions: redness, swelling, small lumps
• Digestive changes: vomiting, reduced appetite
• Behavior changes: restlessness or unusual vocalization

Severe hypoglycemia is the most important risk and requires urgent veterinary care. Other rare risks include allergic reactions and local infection. Certain conditions, including concurrent infections, pancreatitis, Cushing’s disease, or sudden changes in diet, can alter insulin needs. Keep glucose monitoring supplies available as advised by your veterinarian. If you suspect low blood sugar, provide a quick source of glucose if instructed previously by your clinic and seek guidance promptly.

Drug Interactions and Cautions

Drugs that can raise blood glucose may reduce insulin effectiveness, including glucocorticoids, progestogens, and some diuretics. Agents that increase insulin effect include salicylates and some sulfonamides. Beta‑blockers can mask signs of low blood sugar. Alcohol, if ingested by pets, may worsen hypoglycemia. Always tell your veterinarian about all medicines, supplements, and special diets your pet receives. Do not change doses of any therapy without veterinary guidance.

When a new medicine is started or stopped, your prescriber may recommend closer monitoring. Illness, surgery, or heat cycles can change insulin requirements. Report appetite shifts, vomiting, diarrhea, or behavior changes promptly so your veterinary team can advise.

What to Expect Over Time

Stabilization often requires careful monitoring, diet consistency, and follow‑up blood glucose checks. Your veterinarian may adjust the regimen to meet your pet’s needs. Watch for clinical signs and keep a daily log of food, injections, water intake, and behavior. With adherence and regular check‑ins, most pets can maintain steady control and a predictable routine.

Over weeks, you may notice improved energy, more normal thirst, and weight stabilization. Regular rechecks help confirm progress and catch issues early. Bring your dosing log to each visit to support data‑driven decisions.

Compare With Alternatives

Another veterinary insulin option is protamine zinc insulin, supplied as the Prozinc® Vial. If your prescriber prefers a pen device, consider Caninsulin® Cartridges paired with a compatible pen. Learn more about formats in Insulin Cartridges. In the United States, a related porcine insulin is marketed as Vetsulin. Your veterinarian will recommend the formulation and device that best fit your pet and your home routine.

Availability and Substitutions

Stock can vary. If an item is unavailable, your veterinarian may recommend a therapeutically suitable alternative or different presentation.

If you face a shortage, your prescriber will guide any substitution and monitoring plan. We do not quote restock dates.

Patient Suitability and Cost-Saving Tips

Most stable adult dogs and cats with diabetes can be candidates for this therapy when closely supervised by a veterinarian. Pets with diabetic ketoacidosis, severe illness, or poor appetite need immediate veterinary care and individualized plans before routine home dosing. To manage costs and reduce trips, consider multi‑vial fills if your prescriber authorizes them, and set calendar reminders for reorders. Review options across our Pet Medications catalogue, and ask about simpler device choices if dexterity is a concern.
