What is Victoza (liraglutide) used for?
- Victoza is used in combination with metformin, with metformin and a sulfonylurea, with metformin and a sodium glucose cotransporter 2 inhibitor (SGLT2i), or basal insulin to improve blood sugar levels in adults with type 2 diabetes.
- Victoza is used in combination with metformin with or without basal insulin to improve blood sugar levels in adolescents and children aged 10 years and above with type 2 diabetes.
- Victoza may be used on its own if your blood sugar is not properly controlled by diet and exercise alone and you cannot use metformin.
- If you have type 2 diabetes and have a history of heart disease (such as a past heart attack, heart failure, or stroke), Victoza can be used along with diet and exercise to lower your risk of dying from events related to your heart or blood vessels.
- Victoza should not be used in type 1 diabetes (formerly known as insulin-dependent diabetes mellitus or IDDM).
How does Victoza work?
Victoza belongs to a class of medicines called GLP-1 analogue. Victoza helps your body to make more insulin when your blood sugar is high.
What is type 2 diabetes?
Type 2 diabetes is a condition in which your body does not make enough insulin, and/or does not use the insulin that your body produces as well as it should. When this happens, sugar (glucose) builds up in the blood. This can lead to serious problems.
What are the ingredients in Victoza?
Medicinal ingredients: Liraglutide
Non-medicinal ingredients: Disodium phosphate dihydrate, propylene glycol, phenol and water for injections
What strengths is Victoza available in?
Pre-filled multidose pen that can deliver 30 doses of 0.6 mg, 15 doses of 1.2 mg or 10 doses of 1.8 mg.
Who should not use Victoza?
- You or a member of your family has ever had medullary thyroid cancer.
- You have Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
- You are allergic to any of the ingredients in Victoza.
- You are pregnant or breastfeeding.
To help avoid side effects and ensure proper use, talk to your healthcare professional before you take Victoza. Talk about any health conditions or problems you may have, including if you:
- Or a member of your family has or has had medullary thyroid carcinoma, or if you have Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
- Have type 1 diabetes.
- Have ever had diabetic ketoacidosis (increased ketones in the blood or urine).
- Have ever had an allergic reaction to Victoza.
- Have a high heart rate (fast pulse).
- Have a condition called heart block.
- Have any heart disease, such as angina, heart rhythm disturbances or congestive heart failure; or if you have ever had a myocardial infarction (heart attack).
- Have kidney problems.
- Have liver problems.
- Have gastrointestinal (digestive) problems.
- Have ever had pancreatitis.
- Are breastfeeding or plan to breastfeed.
- Are pregnant or plan to become pregnant.
- Have severe vomiting and/or diarrhea and/or dehydration.
When initiating treatment with Victoza, you may in some cases experience loss of fluids/dehydration, e.g. in case of vomiting, nausea and diarrhea. It is important to avoid dehydration by drinking plenty of fluids. Worsening of renal function may sometimes require hemodialysis. Contact your doctor if you have any questions or concerns.
Victoza may increase heart rate and could cause changes known as PR prolongation, which are detected by electrocardiogram (ECG) tracings. Increased heart rate is the same as a faster pulse. Rarely, drugs with these effects can cause changes in heart rhythm that could result in dizziness, palpitations (a feeling of rapid, pounding, or irregular heart beat), fainting or death. These heart rhythm changes are more likely if you have heart disease, or if you are taking certain other drugs. It is important to follow your doctor’s advice about the dose of Victoza or about any special tests that you may need. See ‘What are possible side effects from using Victoza?’
Victoza is not recommended for use in children under 10 years of age.
Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.
In particular, tell your doctor, Diabetes Nurse Educator or pharmacist if you are using any of the following medicines for diabetes:
- A sulfonylurea medicine (such as glibenclamide or glimepiride). This is because using Victoza at the same time may cause your blood sugar to get too low (hypoglycemia).
- When you first start using these medicines together, your doctor may tell you to lower the dose of the sulfonylurea medicine.
- Insulin. You may get hypoglycemia (low blood sugar) when using Victoza with insulin as insulin increases the risk of hypoglycemia. See ‘What are possible side effects from using Victoza?’
- If you are not sure if the medicines you are taking contain a sulfonylurea, ask your doctor, Diabetes Nurse Educator or pharmacist.
What medications may interact with Victoza?
The following list includes some, but not all, of the drugs that may increase the risk of heart rhythm problems while receiving Victoza. You should check with your doctor or pharmacist before taking any other medication with Victoza:
- Drugs to treat hypertension
- Drugs to treat heart failure
- Drugs to treat HIV infection
- Drugs to treat attention deficit-hyperactivity disorder
- Drugs to suppress appetite/cause weight loss
- Drugs to treat asthma
How to take Victoza?
Take Victoza exactly as your doctor has prescribed.
Victoza is an injection which is given under the skin (subcutaneously). Do not inject it into a vein or muscle.
Before you use the pen for the first time, your doctor or Diabetes Nurse Educator will show you how to use it. The best places to give yourself the injection are the front of your thighs, the front of your waist (abdomen) or your upper arm. You can give yourself the injection at any time of the day. (see ‘Instructions for using the Victoza (liraglutide injection) pen’).
Do not share your Victoza pen with anyone else, even if the needle is changed. Do not reuse or share needles with another person including family members. You may give another person an infection or get an infection from them.
What is the usual dose of Victoza?
Victoza can be taken at any time of the day. It does not matter when you take it in relation to meals.
The usual starting dose is 0.6 mg once a day. Your doctor will tell you how long to keep taking this dose. It will be for at least one week. Your dose may be increased to 1.2 mg once a day if your blood glucose is not under control. If your blood glucose is not controlled with a dose of 1.2 mg, your doctor may tell you to increase the dose to 1.8 mg once a day. Do not change your dose unless your doctor has told you to.
You will not need to test your blood sugar levels each day in order to adjust your dose of Victoza. However, if you are taking a sulfonylurea medicine as well as Victoza, your doctor may advise you to test your blood sugar levels. This will help your doctor to decide if the dose of the sulfonylurea needs to be changed.
For children and adolescents starting Victoza, your doctor may advise you to test your blood sugar levels to monitor for hypoglycemia (low blood sugar).
What to do if you overdose on Victoza?
Warning: If you think you have taken too much Victoza, contact your healthcare professional, hospital emergency department or regional poison control centre immediately, even if there are no symptoms.
If you use more Victoza than you should, talk to your doctor straight away. You may need medical treatment. If you use too much Victoza you may feel sick (have nausea), become sick (vomit), or experience low blood sugar (hypoglycemia). Please refer to ‘Common (affects less than 1 in 10 people)’ for early warning signs of low blood sugar.
What to do if you miss a dose of Victoza?
If a dose of Victoza is missed take your dose on the next day as usual. Do not take an extra dose or increase the dose on the following day to make up for the missed dose.
Do not stop using Victoza without talking to your doctor. If you stop using it, your blood sugar levels may increase.
What are possible side effects from using Victoza?
These are not all the possible side affects you may feel when taking Victoza. If you experience any side effects not listed here, contact your healthcare professional.
Like all medicines, Victoza can cause side effects. The following side effects may happen with this medicine.
Very common (affects more than 1 in 10 people):
- Feeling sick (nausea). This usually goes away over time.
Common (affects less than 1 in 10 people):
