Lantus (insulin glargine) for Cats and Dogs

Lantus helps treat diabetes in cats by normalizing the glucose level in the blood. When your cat has a normal level of glucose in the blood the body works as it should and your cat may have fewer diabetic symptoms. Lantus is insulin glargine, a long-acting form of insulin formulated for injection underneath the skin (subcutaneously). Lantus is a U-100 insulin, meaning there are 100 dosing units per milliliter (mL).

  • Regulates blood sugar levels
  • Daily dosing
  • Formulated for subcutaneous (under the skin) injection
