Insulin degludec is an long-acting insulin, similar to the insulin produced by the pancreas in our body to lower glucose levels. It replaces the insulin normally produced in our body and acts longer than regular insulin.

By controlling glycemia control, diabetics can avoid serious complications such as nerve problems, kidney damage, blindness, loss of limbs, stroke or heart attack.

Insulin degludec is often prescribed in combination with a short-acting insulin. Your doctor may also recommend making dietary and exercise as part of your treatment.

What is Tresiba?

Tresiba (insulin degludec) is a long-acting insulin taken once daily to help improve glycemic control in patients with type 1 and type 2 diabetes over the age of 1.

Insulin degludec replaces the insulin the body normally produces. It acts longer than regular insulin and provides a low steady release throughout the day. It helps blood glucose get into the body’s cells to be used as energy.

Insulin degludec can be used along with other diabetes drugs including a shorter-acting insulin product.

What is Tresiba FlexTouch U-100?

Tresiba FlexTouch U-100 (100 units/mL) Pen is as a pre-filled disposable pen that contains 300 units of insulin.


Insulin degludec should be used in combination with a healthy diet and regular exercise to control glycemic levels. Through proper blood sugar control, patients can avoid adverse side effects such as kidney damage, nerve problems, loss of sexual function or loss of limbs. Proper management of diabetes can help avoid heart attack or stroke.

How does the Tresiba FlexTouch U-100 work?

This medication is to be injected under the skin (subcutaneously).

Side Effects in Detail

Hypoglycemia (low blood sugar)

Hypoglycemia is the most common side effect with using insulin, including Tresiba.

Symptoms of hypoglycemia may include:

  • increased thirst
  • increased urination
  • drowsiness
  • flushing
  • difficulty breathing
  • fruity breath
  • confusion
  • hunger
  • blurred vision
  • tingling hands/feet

To avoid severe episodes of hypoglycemia, patients should carry a glucose tablet, sugary snack (such as hard candy, raisins, table, sugar, jelly beans) or sugary drink (fruit juice, non-diet soda).

Patients who experience severe hypoglycemia may require getting an emergency glucagon kit. Family and friends should be instructed on what to do in the event a diabetic has loss consciousness and they need to administer glucagon.

To prevent hypoglycemia, eat meals on a regular schedule and do not skip meals. Inform your doctor if you experience hypoglycemia so they can tell you what to do if you miss a dose or how to manage episodes of hypoglycemia.

Hypokalemia (low potassium)

Signs of low potassium levels may include weakness, irregular heartbeat or muscle cramps.

Peripheral Edema

Tresiba, like other insulin medications, may cause sodium retention and edema. In clinical studies, it was reported that edema occurred in 0.9% of patients with type 1 diabetes and 3% of patients with type 2 diabetes.

This is not the complete list of side effects. If you would like to report side effects to the FDA call 1-800-FDA-1088.


To avoid dosing errors or potential overdose, never extract insulin from a Tresiba FlexTouch pen using a syringe.

Let your doctor know if you have any important notes about your medical history, especially if you have/had liver or kidney disease. Inform your doctor if you have any allergies to insulin degludec or any of its ingredients.

Before going into surgery, inform your doctor or dentist if you are currently taking insulin. This should also include other prescriptions, OTC medications, herbal supplements and vitamins.

If patients miss a dose, they should continue their insulin treatment as usual. Pediatric patients should consult their doctor if they miss a dose and should monitor their blood glucose levels closely.

If you are travelling across time zones you may require changing your insulin schedule. When travelling, be sure to bring extra insulin & diabetes supplies with you.

Never share Tresiba pens, needles or syringes with others, even if the needle has been changed, as it can lead to spreading infection or transmission of blood-borne pathogens.

Hypoglycemia (low blood sugar) is the most common side effect with any insulin, including Tresiba. Severe hypoglycemia can cause serious side effects such as seizures, be life-threatening or be fatal.

Repeated injections into the same area may result in lipodystrophy or localized cutaneous amyloidosis which can result in hypoglycemia. Patients who have injected into areas that have had lipodystrophy or amyloidosis should be instructed to change injection sites.

Since hypoglycemia can impair concentration or vision, it’s important to assess how your body handles hypoglycemia or consult your doctor whether its safe to operate heavy machinery or drive.

Limit your alcohol consumption wile taking Tresiba as it can increase your risk of hypoglycemia.


Tresiba, like other insulin products can impact potassium levels. If untreated, hypokalemia can lead ot potential risks such as ventricular arrhythmia, respiratory paralysis or even death. Patients may need to monitor potassium levels especially if using serum potassium concentrations or potassium-lowering medications.
