Humulin N Insulin is an injectable prescribed for the treatment of diabetes mellitus that helps to maintain normal blood sugar. Humulin N Insulin allows the blood sugar to be properly used within the body by allowing the blood sugar to enter the cells so it can be used for energy.

Key Benefits

  • Longer activity duration and slower action onset than most other types of insulin on the market
  • Intermediate-acting insulin
  • Rapidly improves blood glucose levels
  • Controls the glucose level of diabetic dogs

Humulin N is special suspension of human insulin mixed with other ingredients for treating pets with diabetes. Humulin N is an intermediate-acting insulin. Injecting your pet with Humulin N as directed by your veterinarian will help stabilize your pet's blood sugar levels and reduce symptoms of diabetes. This medication is designed to work quickly so you should see improvement in your pet in a matter of days after the first injections.

How It Works

Humulin N is effective in controlling hyperglycemia in diabetic dogs. It is a man-made form of a naturally-produced pancreatic hormone. It lowers the glucose (sugar) levels in the blood. Diabetic mellitus occurs when the body does not naturally produce an adequate amount of insulin.


HUMULIN N is used in the treatment of diabetes mellitus in multiple species including cats and dogs. It comes in various forms and strengths with corresponding syringes for each strength.


Use according to your veterinarian's instructions. Doses vary considerably between animals. In some cases, insulin may need to be given twice a day; it may need to be given at higher doses to get diabetes under control, then decreased; or doses may need to be increased over time.


Do not inject insulin at the same site day after day or lipodystrophic reactions can occur. Do not change the pet's food, feeding schedule, or exercise schedule once regulated for that food and schedule. Do not use any insulin that has been frozen or exposed to direct heat or light. Make sure you are always using the appropriate type of syringe for the type of insulin you have.

This drug is FDA-approved for human use. However, it is common practice for veterinarians to prescribe such drugs for use in dogs and cats.

Possible Side Effects

Adverse effects of insulin therapy may include hypoglycemia, insulin-induced hyperglycemia ("Somogyi effect"), insulin antagonism/resistance, rapid insulin metabolism, and local reactions to the "foreign" proteins.


Store in a 36° - 46°F refrigerator, but not in the freezer.

Before using Humulin N, tell your vet about your pet's medical conditions including:

  • Liver or kidney problems.
  • Any other medicines.
  • Heart failure or other heart problems.
  • Pregnancy.

Before you start administering Humulin N, talk to your vet about your pet's low blood sugar and how to manage it.

  • Read the instructions that come with your Humulin N. Use Humulin N exactly as your vet tells you to.
  • Know the type and strength of insulin you're using. Do not change the type of insulin you use unless your vet tells you to.
  • Monitor your pet's blood sugar levels. Ask your vet what the blood sugars should be and when you should check.

Potential side effects include:

  • Hyperglycemia (high blood sugar) if overmedicated
  • Hypoglycemia (low blood sugar) if undermedicated
  • Pitting or thickening of skin at injection site
  • Skin reaction at injection site
