1. What Zegluxen is and what it is used for

The name of your medicine is Zegluxen 6 mg/ml solution for injection in pre-filled pen (referred to as Zegluxen throughout the leaflet).

Your medicine contains the active substance liraglutide. It helps your body reduce your blood sugar level, but only when your blood sugar is too high. It also slows food passage through your stomach and can help prevent heart disease.

Zegluxen is used on its own if your blood sugar is not properly controlled by diet and exercise alone, and you cannot use metformin (another diabetes medicine).

Zegluxen is used with other medicines for diabetes when they are not enough to control your blood sugar levels. These may include:

  • oral antidiabetics (such as metformin, pioglitazone, sulfonylurea, sodium-glucose cotransporter 2 inhibitor (SGLT2i)) and/or insulin.

2. What you need to know before you use Zegluxen

Do not use Zegluxen

  • if you are allergic to liraglutide or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor, pharmacist or nurse before using liraglutide:

  • if you ever had pancreatitis (inflammation of the pancreas which may cause severe pain in the stomach and back which does not go away; (see section 4).

This medicine should not be used if you have type 1 diabetes (your body does not produce any insulin) or diabetic ketoacidosis (a complication of diabetes with high blood sugar and increase in effort to breathe). It is not an insulin and should therefore not be used as a substitute for insulin.

The use of Zegluxen is not recommended if you are on dialysis. The use of Zegluxen is not recommended if you have severe liver disease.

The use of Zegluxen is not recommended if you have severe heart failure.

This medicine is not recommended if you have a severe stomach or gut problem which results in delayed stomach emptying (called gastroparesis), or inflammatory bowel disease.

If you have thyroid disease including thyroid nodules and enlargement of the thyroid gland, consult your doctor.

If you know that you are due to have surgery where you will be under anesthesia (sleeping), please tell your doctor that you are taking Zegluxen.

When initiating treatment with Zegluxen you may in some cases experience loss of fluids/dehydration, e.g. in case of vomiting, nausea and diarrhoea. It is important to avoid dehydration by drinking plenty of fluids. Contact your doctor if you have any questions or concerns.

Children and adolescents

Zegluxen can be used to treat type 2 diabetes in adolescents and children aged 10 years and above. No data are available in children below 10 years of age.

Other medicines and Zegluxen

Please tell your doctor, pharmacist or nurse if you are taking, have recently taken or might take any other medicines.

In particular, tell your doctor, pharmacist or nurse if you are using medicines containing any of the following active substances:

  • Sulfonylurea (such as glimepiride or glibenclamide) or insulin. You may get hypoglycaemia (low blood sugar) when using Zegluxen together with a sulfonylurea or insulin, as sulfonylureas and insulin increase the risk of hypoglycaemia. When you first start using these medicines together, your doctor may tell you to lower the dose of the sulfonylurea or insulin. Please see section 4 for the warning signs of low blood sugar. If you are also taking a sulfonylurea (such as glimepiride or glibenclamide) or insulin, your doctor may tell you to test your blood sugar levels. This will help your doctor to decide if the dose of the sulfonylurea or insulin needs to be changed.
  • If you are using insulin, your doctor will tell you how to reduce the dose of insulin and will recommend you to monitor your blood sugar more frequently, in order to avoid hyperglycaemia (high blood sugar) and diabetic ketoacidosis (a complication of diabetes that occurs when the body is unable to break down glucose because there is not enough insulin).
  • Warfarin or other oral anti-coagulation medicines. More frequent blood testing to determine the ability of your blood to clot may be required.

Pregnancy and breast-feeding

Tell your doctor if you are, you think you might be, or are planning to become pregnant. Zegluxen should not be used during pregnancy because it is not known if it may harm your unborn child.

It is not known if Zegluxen passes into breast milk, therefore do not use this medicine if you are breastfeeding.

Driving and using machines

Low blood sugar (hypoglycaemia) may reduce your ability to concentrate. Avoid driving or using machines if you experience signs of hypoglycaemia. Please see section 4 for the warning signs of low blood sugar. Please consult your doctor for further information on this topic.

Important information about some of the ingredients of Zegluxen

This medicine contains less than 1 mmol sodium (23 mg) per dose. This means that it is essentially ‘sodium free’.

3. How to use Zegluxen

Always use this medicine exactly as your doctor has told you.

Check with your doctor, pharmacist or nurse if you are not sure.

  • The starting dose is 0.6 mg once a day, for at least one week.
  • Your doctor will tell you when to increase it to 1.2 mg once a day.
  • Your doctor may tell you to further increase the dose to 1.8 mg once a day, if your blood glucose is not adequately controlled with a dose of 1.2 mg.

Do not change your dose unless your doctor has told you to.

Zegluxen is given as an injection under the skin (subcutaneous).

Do not inject it into a vein or muscle. The best places to give yourself the injection are the front of your thighs, the front of your waist (abdomen), or your upper arm. Change the place where you inject each day to reduce the risk of developing lumps.

You can give yourself the injection at any time of the day, regardless of meals. When you have found the most convenient time of the day it is preferred that you inject Zegluxen around the same time of the day.

Before you use the pen for the first time, your doctor or nurse will show you how to use it.

Injection needles are not included with the pen. Needles such as BD Ultra-Fine™ disposable needles or NovoFine® disposable needles as thin as 32 G and length up to 8 mm can be used.

A leaflet with detailed instructions for use is provided in this pack.

If you use more Zegluxen than you should

If you use more Zegluxen than you should, talk to your doctor straight away. You may need medical treatment. You may experience nausea, vomiting, diarrhoea or low blood sugar (hypoglycaemia). Please refer to section 4 for warning signs of low blood sugar.

If you forget to use Zegluxen

If you forget a dose, use Zegluxen as soon as you remember.

However, if it is more than 12 hours since you should have used Zegluxen, skip the missed dose. Then take your next dose as usual the following day. Do not take an extra dose or increase the dose on the following day to make up for the missed dose.

If you stop using Zegluxen

Do not stop using Zegluxen without talking to your doctor. If you stop using it, your blood sugar levels may increase.

If you have any further questions on the use of this medicine, ask your doctor, pharmacist or nurse.
