How to Give Vetsulin® Using a U-40 Insulin Syringe

Important dosage information

Doses of insulin are measured in units: 40 IU/mL insulin contains 40 International Units (IU) per milliliter (mL) (1 mL = 1 cc).

Use Vetsulin with U-40 syringes only

These syringes are designed specifically for use in animals. Using a syringe other than a U-40 syringe (such as a U-100 syringe that is designed for use in people) will result in incorrect dosing. This could be dangerous for your cat.

Your veterinarian will prescribe Vetsulin for your cat

Follow your veterinarian's instructions to properly give Vetsulin to your cat. Your veterinarian will:

  • Determine the amount of insulin and frequency needed
  • Advise on proper storage and handling
  • Show how to draw the insulin from the vial
  • Instruct on how to give the injection

When you feel comfortable, your veterinarian and veterinary nurse will give you everything you need to care for your cat's diabetes at home.

Preparing the dose

After washing your hands, take the Vetsulin (porcine insulin zinc suspension) vial out of the refrigerator. Shake the vial until the insulin is uniformly milky, allowing any foam to disperse.

  1. Carefully remove the cap from the needle and insert the needle into the vial.
  2. Turn the vial upside down, making sure the tip of the needle remains in the vial.
  3. Withdraw the correct dose into the U-40 syringe.
  4. Before removing the needle from the vial, check the syringe for any air bubbles.
  5. If bubbles are present, hold the syringe up and tap its side until the bubbles float to the top. Push them out with the plunger and withdraw the correct dose.
  6. Remove the needle from the vial. Be careful that you do not inject yourself.

Giving the injection

Pinch a fold of your cat's skin
Gently insert needle in center of fold of skin, 1–2" from middle of back
Push plunger as far as it will go, pull needle out, and dispose of syringe appropriately

Giving injections may seem daunting–but with practice, it can be easy and fit into your daily routine.

  1. Injection should be given under the skin, 3/4 to 2 inches from the middle of your cat's back, varying from behind the shoulder blades to the middle of the back region and alternating sides.
  2. Gently insert needle in center of folded skin.
  3. Push plunger until all of the insulin is given.
  4. Pull needle out and dispose of syringe into appropriate sharps collector.

Injection Tips:

  • Injection point can depend upon your veterinarian's recommendation and what is best for you and your cat.
  • Alternate injection site between left and right side for comfort and best results. Repeat injections at the same site can lead to ineffective treatment.
