What to know

Evidence-backed context Limited

Roxee has limited cited overview evidence for Insulin Injectable Vial; use the official documents and your veterinarian's instructions for product-specific decisions.

Source: openFDA case USA-USFDACVM-2025-US-055524
Safety signal coverage Reported signals

32 tracked reaction signals; 32 reported cases; 28 serious reports; 2 species groups. These are reporting and label-derived signals for interpretation with a veterinarian.

Source: openFDA case USA-USFDACVM-2025-US-055524
Interpretation guardrail Not causation

Adverse-event reports help form a watch list, but they do not prove the medication caused the reaction and they are not a risk ranking between medications.

Evidence tension

Stronger signal Label / review

Official labels, package inserts, and reviewed summaries carry more weight than isolated reports.

Source: openFDA case USA-USFDACVM-2025-US-055524
Weaker signal Reported data

Case reports and openFDA terms are useful for pattern awareness, but they are incomplete, can include multiple exposures, and do not estimate an individual pet's probability of harm.

What your vet may verify

Fit for this patient Vet check

Verify whether Insulin Injectable Vial fits the pet's species, current diagnosis, age, weight, organ status, pregnancy/lactation status, and concurrent medications.

Evidence limitations Evidence review

Separate label-backed warnings from adverse-event reports and owner observations before changing the plan.

What to watch next

Call sooner if Escalation

Repeated vomiting or diarrhea. Severe lethargy (hard to wake, very low energy). Collapse or fainting.

Bottom line: Use this Insulin Injectable Vial brief as a structured watch list and source map, not as a reason to start, stop, or change treatment without your veterinarian.

Composition / specifications
Each mL contains 40 international units (IU) insulin.

Cats

Indication
For the reduction of hyperglycemia and hyperglycemia-associated clinical signs in cats with diabetes mellitus.
Dosage
The initial recommended dose is 0.1 to 0.3 IU insulin/pound of body weight (0.2 to 0.7 IU/kg) every 12 hours. The dose should be given concurrently with or right after a meal.
Limitations
Federal law restricts this drug to use by or on the order of a licensed veterinarian. Use of a syringe other than a U-40 syringe will result in incorrect dosing. For subcutaneous injection in cats only.

Dogs

Indication

For the reduction of hyperglycemia and hyperglycemia-associated clinical signs in dogs with diabetes mellitus.

Dosage

Starting dose: The recommended starting dose for ProZinc® is 0.2-0.5 IU insulin/pound of body weight (0.5-1.0 IU/kg) once daily. The recommended starting dose for naïve dogs is the lower end of the dose range. The recommended starting dose for dogs with poorly controlled diabetes mellitus and transitioning from another insulin product is the mid to higher end of the dose range based on the veterinarian’s experience with the dog’s medical history and previous insulin dose. When transitioning from another insulin, the dog’s blood glucose and general condition should be closely monitored. When transitioning from another insulin, ProZinc® should be started once daily regardless of the frequency of prior insulin use.

The dose should be given concurrently with or right after a meal. The veterinarian should re-evaluate the dog at appropriate intervals and adjust the dose and frequency based on both clinical signs and laboratory test results (the blood glucose curve values and shape, nadir, and fructosamine) until adequate glycemic control has been attained. In the effectiveness field study, glycemic control was considered adequate if the glucose nadir from a 9-hour blood glucose curve was between 80 and 125 mg/dL, the maximum blood glucose was lessThanEqualTo 300 mg/dL, and clinical signs of hyperglycemia such as polyuria, polydipsia, or weight loss were improved.

Changing to twice daily dosing: Twice daily dosing should be considered if the duration of insulin action is determined to be inadequate with once daily dosing. Use caution when adjusting from once daily to twice daily dosing because ProZinc® may have prolonged duration of action in some dogs. The veterinarian should closely monitor the duration of action using blood glucose curves to avoid the increased risk of hypoglycemia. If twice daily dosing is initiated, the two doses should each be approximately 25% less than the once daily dose required to attain an acceptable glucose nadir. For example, if a dog receiving 10 units of ProZinc® once daily has an acceptable nadir but inadequate duration of activity, the dose should be changed to 7 units twice daily (round down to the nearest whole unit).

Further adjustments in the dosage may be necessary with changes in the dog’s diet, body weight, or concomitant medication, or if the dog develops concurrent infection, inflammation, neoplasia, or an additional endocrine or other medical disorder.

Species: Dog • Cat
Composition / specifications
Each mL contains 40 international units (IU) insulin.
Cats
Indication
For the reduction of hyperglycemia and hyperglycemia-associated clinical signs in cats with diabetes mellitus.
Dosage
The initial recommended dose is 0.1 to 0.3 IU insulin/pound of body weight (0.2 to 0.7 IU/kg) every 12 hours. The dose should be given concurrently with or right after a meal.
Limitations
Federal law restricts this drug to use by or on the order of a licensed veterinarian. Use of a syringe other than a U-40 syringe will result in incorrect dosing. For subcutaneous injection in cats only.
Dogs
Indication

For the reduction of hyperglycemia and hyperglycemia-associated clinical signs in dogs with diabetes mellitus.

Dosage

Starting dose: The recommended starting dose for ProZinc® is 0.2-0.5 IU insulin/pound of body weight (0.5-1.0 IU/kg) once daily. The recommended starting dose for naïve dogs is the lower end of the dose range. The recommended starting dose for dogs with poorly controlled diabetes mellitus and transitioning from another insulin product is the mid to higher end of the dose range based on the veterinarian’s experience with the dog’s medical history and previous insulin dose. When transitioning from another insulin, the dog’s blood glucose and general condition should be closely monitored. When transitioning from another insulin, ProZinc® should be started once daily regardless of the frequency of prior insulin use.

The dose should be given concurrently with or right after a meal. The veterinarian should re-evaluate the dog at appropriate intervals and adjust the dose and frequency based on both clinical signs and laboratory test results (the blood glucose curve values and shape, nadir, and fructosamine) until adequate glycemic control has been attained. In the effectiveness field study, glycemic control was considered adequate if the glucose nadir from a 9-hour blood glucose curve was between 80 and 125 mg/dL, the maximum blood glucose was lessThanEqualTo 300 mg/dL, and clinical signs of hyperglycemia such as polyuria, polydipsia, or weight loss were improved.

Changing to twice daily dosing: Twice daily dosing should be considered if the duration of insulin action is determined to be inadequate with once daily dosing. Use caution when adjusting from once daily to twice daily dosing because ProZinc® may have prolonged duration of action in some dogs. The veterinarian should closely monitor the duration of action using blood glucose curves to avoid the increased risk of hypoglycemia. If twice daily dosing is initiated, the two doses should each be approximately 25% less than the once daily dose required to attain an acceptable glucose nadir. For example, if a dog receiving 10 units of ProZinc® once daily has an acceptable nadir but inadequate duration of activity, the dose should be changed to 7 units twice daily (round down to the nearest whole unit).

Further adjustments in the dosage may be necessary with changes in the dog’s diet, body weight, or concomitant medication, or if the dog develops concurrent infection, inflammation, neoplasia, or an additional endocrine or other medical disorder.
