What is Victoza?
Victoza is an injectable prescription medicine used along with diet and exercise to lower blood sugar (glucose) in adults and children who are 10 years of age and older with type 2 diabetes mellitus.
It is also used to reduce the risk of major cardiovascular events such as heart attack, stroke or death in adults with type 2 diabetes mellitus with known heart disease.
Victoza is not for use in people with type 1 diabetes. It should not be used with other medicines that contain liraglutide. It is not known if Victoza is safe and effective to lower blood sugar (glucose) in children under 10 years of age.
Description
VICTOZA contains liraglutide, an analog of human GLP-1 and acts as a GLP-1 receptor agonist. The peptide precursor of liraglutide, produced by a process that includes expression of recombinant DNA in Saccharomyces cerevisiae, has been engineered to be 97% homologous to native human GLP-1 by substituting arginine for lysine at position 34. Liraglutide is made by attaching a C-16 fatty acid (palmitic acid) with a glutamic acid spacer on the remaining lysine residue at position 26 of the peptide precursor. The molecular formula of liraglutide is C172H265N43O51 and the molecular weight is 3751.2 Daltons. The structural formula (Figure 1) is:
Figure 1 Structural Formula of liraglutide
VICTOZA injection is a sterile, aqueous, clear, colorless or almost colorless solution for subcutaneous use. Each 1 mL of VICTOZA solution contains 6 mg of liraglutide and the following inactive ingredients: disodium phosphate dihydrate, 1.42 mg; propylene glycol, 14 mg; phenol, 5.5 mg; and water for injection. VICTOZA has a pH of approximately 8.15, hydrochloric acid or sodium hydroxide may be added to adjust pH. Each pre-filled pen contains a 3 mL solution of VICTOZA equivalent to 18 mg liraglutide (free-base, anhydrous).
Mechanism of Action
Liraglutide is an acylated human Glucagon-Like Peptide-1 (GLP-1) receptor agonist with 97% amino acid sequence homology to endogenous human GLP-1(7-37). GLP-1(7-37) represents <20% of total circulating endogenous GLP-1. Like GLP-1(7-37), liraglutide activates the GLP-1 receptor, a membrane-bound cell-surface receptor coupled to adenylyl cyclase by the stimulatory G-protein, Gs, in pancreatic beta cells. Liraglutide increases intracellular cyclic AMP (cAMP) leading to insulin release in the presence of elevated glucose concentrations. This insulin secretion subsides as blood glucose concentrations decrease and approach euglycemia. Liraglutide also decreases glucagon secretion in a glucose-dependent manner. The mechanism of blood glucose lowering also involves a delay in gastric emptying.
GLP-1(7-37) has a half-life of 1.5-2 minutes due to degradation by the ubiquitous endogenous enzymes, dipeptidyl peptidase IV (DPP-IV) and neutral endopeptidases (NEP). Unlike native GLP-1, liraglutide is stable against metabolic degradation by both peptidases and has a plasma half-life of 13 hours after subcutaneous administration. The pharmacokinetic profile of liraglutide, which makes it suitable for once daily administration, is a result of self-association that delays absorption, plasma protein binding and stability against metabolic degradation by DPP-IV and NEP.
What is the most important information I should know about Victoza?
Victoza may cause serious side effects, including:
- Possible thyroid tumors, including cancer. Tell your healthcare provider if you get a lump or swelling in your neck, hoarseness, trouble swallowing, or shortness of breath. These may be symptoms of thyroid cancer. In studies with rats and mice, Victoza and medicines that work like Victoza caused thyroid tumors, including thyroid cancer. It is not known if Victoza will cause thyroid tumors or a type of thyroid cancer called medullary thyroid carcinoma (MTC) in people.
- Do not use Victoza if you or any of your family have ever had a type of thyroid cancer called medullary thyroid carcinoma (MTC), or if you have an endocrine system condition called Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).
Who should not use Victoza?
Do not use Victoza if:
- you or any of your family have ever had a type of thyroid cancer called medullary thyroid carcinoma (MTC) or if you have an endocrine system condition called Multiple Endocrine Neoplasia syndrome type 2 (MEN 2).

Before using Victoza, talk to your healthcare provider about low blood sugar and how to manage it. Tell your healthcare provider if you are taking other medicines to treat diabetes, including insulin or sulfonylureas.
Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine.
How should I use Victoza?
- Read the Instructions for Use that come with Victoza.
- Use Victoza exactly as your healthcare provider tells you to.
- Your healthcare provider should show you how to use Victoza before you use it for the first time.
- Use Victoza 1 time each day, at any time of the day.
- Victoza may be taken with or without food.
- Victoza is injected under the skin (subcutaneously) of your stomach (abdomen), thigh, or upper arm. Do not inject Victoza into a muscle (intramuscularly) or vein (intravenously).
- Do not mix insulin and Victoza together in the same injection.
- You may give an injection of Victoza and insulin in the same body area (such as your stomach area), but not right next to each other.
- If you miss a dose of Victoza, take the missed dose at the next scheduled dose. Do not take 2 doses of Victoza at the same time.
- If you take too much Victoza, call your healthcare provider right away. Taking too much Victoza may cause severe nausea, severe vomiting, and low blood sugar (hypoglycemia).
- Change (rotate) your injection site with each injection. Do not use the same site for each injection.
- Do not share your Victoza pen with other people, even if the needle has been changed. You may give other people a serious infection, or get a serious infection from them.
- The Victoza pen you are using should be thrown away 30 days after you start using it.
Your dose of Victoza and other diabetes medicines may need to change because of:
- change in level of physical activity or exercise, weight gain or loss, increased stress, illness, change in diet or because of other medicines you take.
What are the possible side effects of Victoza?
Victoza may cause serious side effects, including:
- See “What is the most important information I should know about Victoza?”
- Inflammation of your pancreas (pancreatitis). Stop using Victoza and call your healthcare provider right away if you have severe pain in your stomach area (abdomen) that will not go away, with or without vomiting. You may feel the pain from your abdomen to your back.
- Low blood sugar (hypoglycemia). Your risk for getting low blood sugar may be higher if you use Victoza with another medicine that can cause low blood sugar, such as a sulfonylurea or insulin. In children who are 10 years of age and older, the risk for low blood sugar may be higher with Victoza regardless of use with another medicine that can also lower blood sugar. Signs and symptoms of low blood sugar may include:
- dizziness or light-headedness
- sweating
- confusion or drowsiness
- headache
- blurred vision
- slurred speech
- shakiness
- fast heartbeat
- anxiety, irritability, or mood changes

General information about the safe and effective use of Victoza
Medicines are sometimes prescribed for purposes other than those listed in a Medication Guide. Do not use Victoza for a condition for which it was not prescribed. Do not give Victoza to other people, even if they have the same symptoms that you have. It may harm them. If you would like more information, talk with your healthcare provider. You can ask your pharmacist or healthcare provider for information about Victoza that is written for health professionals.
How should I store Victoza?
Before use:
- Store your new, unused Victoza pen in the refrigerator at 36ºF to 46ºF (2ºC to 8ºC).
- If Victoza is stored outside of refrigeration (by mistake) prior to first use, it should be used or thrown away within 30 days.
- Do not freeze Victoza or use Victoza if it has been frozen. Do not store Victoza near the refrigerator cooling element.
Pen in use:
- Use a Victoza pen for only 30 days. Throw away a used Victoza pen 30 days after you start using it, even if some medicine is left in the pen.
- Store your Victoza pen at 59ºF to 86ºF (15ºC to 30ºC), or in a refrigerator at 36ºF to 46ºF (2°C to 8°C).
- When carrying the pen away from home, store the pen at a temperature between 59ºF to 86ºF (15ºC to 30ºC).
