Long Acting Insulin

Glargine (Lantus®, Basaglar®, Semglee®), Detemir (Levemir®), ___________________

Why does my child need this medicine?

  • Long acting insulin lowers blood sugar levels in children with type 1 or type 2 diabetes throughout the day and night.
  • Long acting insulin starts to work in about 2 to 4 hours. It works for about 20 to 24 hours for most people.
  • Long acting insulin does not bring blood sugars down quickly and is not used to correct a high blood sugar right away.

What does this medicine look like?

  • It comes as a clear liquid in a vial, cartridge or a prefilled pen.

How and when should I give my child this medicine?

  • Use an insulin syringe or insulin pen to give this medicine.
  • Give it at the same time each day. Most often, this is at bedtime.
  • Use a new needle every time you give an injection. Remove the needle after the injection.
  • Your health care team will teach you how to do this.

Special advice for giving this medicine with other medicines:

  • Do not mix this insulin with rapid acting insulin in a syringe.
  • If you give your child rapid acting at the same time as long acting insulin, you must give the two injections in different places of their body.

Possible side effects

  • If your child has these or other side effects, tell the doctor, nurse, or pharmacist:
  • Low blood sugar. Follow low blood sugar guidelines given by the diabetes clinic.
  • Lumps under the skin. This happens if the insulin is given many times in the same spot. Do not give insulin into a lump as it will not work well.
  • Allergic reaction (mild): Redness or itching at the injection site.
  • Allergic reaction (moderate or severe): Call your doctor or nurse right away if your child has:
    • Rash all over the body
    • Trouble breathing (call 911)
    • Fast heart rate
    • Sweating
