How Tresiba® works

Once-daily injection

Tresiba® is taken by injection once a day and is available in a vial or the FlexTouch® pen. Once injected, Tresiba® helps the sugar in your blood get into your cells. Sugar provides your cells with energy needed to fuel your body.

Molecular design

The molecular design of Tresiba® allows it to connect like a string of pearls.

Around-the-clock control

Tresiba® releases slow and steady from the ends of its molecular chain for a full 24 hours of blood sugar control with powerful A1C reductions.

Reasons to ask about Tresiba®

Only Tresiba® allows adults to vary their daily dosing interval by 8 to 40 hours, providing around-the-clock control while still maintaining blood sugar control. While taking your insulin at the same time every day is recommended, if you miss or delay your Tresiba® dose, simply take it as soon as you can, then return to your normal dosing schedule. Just be sure to leave at least 8 hours between doses.

What to know about low blood sugar

The goal of any diabetes treatment is to lower blood sugar. However, it is possible for your blood sugar to drop too low. Ask your health care provider what blood sugar level is considered low for you.

If you are taking insulin, you should know the symptoms of low blood sugar (also called hypoglycemia):

  • Sweaty
  • Hungry
  • Confused
  • Shaky
  • Lightheaded
  • Dizzy
  • Sleepy
  • Nervous

Learn more about hypoglycemia with this downloadable fact sheet.

These are not all the possible symptoms of low blood sugar. Talk to your health care provider to get a complete list of symptoms.

Severe low blood sugar

If these symptoms go untreated, low blood sugar can become severe. People having a severe low blood sugar episode (or severe hypoglycemia) may require assistance from another person for recovery. Severe low blood sugar may lead to seizures and loss of consciousness.

  • Know the type and strength of insulin you take. Do not change the type of insulin you take unless your health care provider tells you to

    • Do not use the exact same spot for each injection.
    • Do not inject where the skin has pits, is thickened, or has lumps.
    • Do not inject where the skin is tender, bruised, scaly or hard, or into scars or damaged skin.
  • Adults - If you miss or are delayed in taking your dose of Tresiba®:
    • Take your dose as soon as you remember, then continue with your regular dosing schedule
    • Make sure there are at least 8 hours between doses
  • If children miss a dose of Tresiba®:
    • Call the healthcare provider for information and instructions about checking blood sugar levels more often until the next scheduled dose of Tresiba®
  • For children who need less than 5 units of Tresiba® each day, use a Tresiba® U-100 vial
  • Check your blood sugar levels. Ask your health care provider what your blood sugar levels should be and when you should check them
  • Do not reuse or share your needles or syringes with other people. You may give them a serious infection, or get a serious infection from them
  • Never inject Tresiba® into a vein or muscle

  • Low potassium in your blood (hypokalemia)
  • Heart failure in some people if taken with thiazolidinediones (TZDs). This can happen even if you have never had heart failure or heart problems. If you already have heart failure, it may get worse while you take TZDs with Tresiba®. Tell your health care provider if you have any new or worse symptoms of heart failure including shortness of breath, tiredness, swelling of your ankles or feet, and sudden weight gain

Your insulin dose may need to change because of change in level of physical activity or exercise, increased stress, change in diet, weight gain or loss, or illness.

Common side effects may include reactions at the injection site, itching, rash, serious allergic reactions (whole body reactions), skin thickening or pits at the injection site (lipodystrophy), weight gain, and swelling of your hands and feet.

Get emergency medical help if you have trouble breathing, shortness of breath, fast heartbeat, swelling of your face, tongue, or throat, sweating, extreme drowsiness, dizziness, or confusion.
