About Victoza®
What is Victoza® (liraglutide) injection?
Victoza® is an injectable GLP-1 receptor agonist indicated as an adjunct to diet and exercise to improve glycemic control in patients 10 years and older with type 2 diabetes mellitus and to reduce the risk of major adverse cardiovascular events (cardiovascular death, nonfatal myocardial infarction, or non-fatal stroke) in adults with type 2 diabetes mellitus and established cardiovascular disease.1
How does Victoza® work in the body?
Victoza® works in the liver, pancreas, and gut to control blood glucose by lowering hepatic glucose output, increasing insulin production, and slowing gastric emptying.1
How is the Victoza® molecule different than Ozempic® (semaglutide) injection 0.5 mg or 1 mg?
Structural modifications of both the Victoza® and Ozempic® molecules prevent degradation by DPP-4 and prolong incretin activity.1,2 Victoza® is a GLP-1 analog with 97% similarity to human GLP-1.1 Ozempic® is a GLP-1 analog with 94% similarity to human GLP-1.2
Ozempic® delivers week-long coverage with an elimination half-life of ~7 days.2 See the Ozempic® molecule.
Ozempic® is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus and to reduce the risk of major adverse cardiovascular (CV) events (CV death, nonfatal myocardial infarction, or nonfatal stroke) in adults with type 2 diabetes mellitus and established CVD.

Should I adjust the dose of Victoza® for my adult patients who have renal impairment?
No dose adjustment of Victoza® is recommended for patients with renal impairment. In the Victoza® arm of the LEADER trial, no overall differences in safety or efficacy were seen in patients with mild, moderate, or severe renal function compared to those with normal renal function.1
There is limited experience with Victoza® in patients with end-stage renal disease. There have been postmarketing reports of acute renal failure and worsening of chronic renal failure, which may sometimes require hemodialysis.1 Use caution when initiating or escalating doses of Victoza® in patients with renal impairment.
What was the trial that studied the efficacy of Victoza® in pediatric patients?
In the ELLIPSE trial, 134 patients with type 2 diabetes aged 10 to 17 years were randomized to receive liraglutide up to 1.8 mg/day or placebo, in combination with metformin with or without basal insulin over a 26-week, double-blinded period followed by a 26-week, open-label extension period. The primary endpoint was change in A1C from baseline at Week 26.3
What were the cardiovascular outcomes trial (CVOT) results for LEADER?
In LEADER, Victoza® reduced the risk of MACE in adults with type 2 diabetes and established cardiovascular disease. See LEADER results here.
The CV safety of once-weekly Ozempic® was also evaluated in a 2-year CVOT.2,a,b View the CVOT results for Ozempic® and consider if it’s an option for your appropriate adult patients.
aThe primary composite endpoint was the time from randomization to first occurrence of a MACE: CV death, nonfatal myocardial infarction, or nonfatal stroke.
bResults apply to Ozempic® plus standard of care vs standard of care alone in SUSTAIN 6 trial.
Is there a once-weekly GLP-1 RA option available?
Ozempic® is a once-weekly GLP-1 RA therapy with dose options for a range of patients:
- 0.5 mg
- 1 mg
- 2 mg
Ozempic® is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus and to reduce the risk of major adverse cardiovascular (CV) events (CV death, nonfatal myocardial infarction, or nonfatal stroke) in adults with type 2 diabetes mellitus and established CVD.2

About taking Victoza®
How often do patients need to take Victoza®?
Patients should inject Victoza® subcutaneously once daily at any time of day, independently of meals, in the abdomen, thigh, or upper arm.1
For adult patients interested in a once-weekly option, consider Ozempic®. It is administered by the patient once weekly on the same day each week, at any time of the day, with or without meals.
What are the dosages for Victoza®?
Victoza® comes in a prefilled, multidose pen that delivers doses of 0.6 mg, 1.2 mg, or 1.8 mg.1
What is the proper dosage of Victoza® for adult patients with type 2 diabetes?
Initiate Victoza® with a dose of 0.6 mg daily for one week for your adult patients with type 2 diabetes. The 0.6 mg dose is a starting dose intended to reduce gastrointestinal symptoms during initial titration and is not effective for glycemic control in adults.
After one week at 0.6 mg per day, increase the dose to 1.2 mg daily. If additional glycemic control is required, increase the dose to 1.8 mg daily after at least one week of treatment with the 1.2 mg daily dose.1
What is the proper dosage of Victoza® for pediatric patients aged 10 years and older with type 2 diabetes?
Initiate Victoza® with a dose of 0.6 mg daily. After at least one week at 0.6 mg daily, the dose may be increased to 1.2 mg daily if additional glycemic control is required.
If additional glycemic control is required, increase the dose to 1.8 mg daily after at least one week of treatment with the 1.2 mg daily dose.1

Important Safety Information for Victoza® (liraglutide) injection 1.2 mg or 1.8 mg
WARNING: RISK OF THYROID C-CELL TUMORS
- Liraglutide causes dose-dependent and treatment-duration-dependent thyroid C-cell tumors at clinically relevant exposures in both genders of rats and mice. It is unknown whether Victoza® causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans, as the human relevance of liraglutide-induced rodent thyroid C-cell tumors has not been determined.
- Victoza® is contraindicated in patients with a personal or family history of MTC and in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Counsel patients regarding the potential risk for MTC with the use of Victoza® and inform them of symptoms of thyroid tumors (eg, a mass in the neck, dysphagia, dyspnea, persistent hoarseness). Routine monitoring of serum calcitonin or using thyroid ultrasound is of uncertain value for early detection of MTC in patients treated with Victoza®.
Indications and Limitations of Use
Victoza® (liraglutide) injection 1.2 mg or 1.8 mg is indicated as an adjunct to diet and exercise to improve glycemic control in patients 10 years and older with type 2 diabetes mellitus and to reduce the risk of major adverse cardiovascular events (cardiovascular death, nonfatal myocardial infarction, or non-fatal stroke) in adults with type 2 diabetes mellitus and established cardiovascular disease.
- Victoza® should not be used in patients with type 1 diabetes.
- Victoza® contains liraglutide and should not be coadministered with other liraglutide-containing products.
Important Safety Information cont.
Contraindications
- Victoza® is contraindicated in patients with a personal or family history of MTC or in patients with MEN 2, and in patients with a serious hypersensitivity reaction to liraglutide or to any of the excipients in Victoza®. Serious hypersensitivity reactions including anaphylactic reactions and angioedema have been reported with Victoza®.
Warnings and Precautions
- Risk of Thyroid C-cell Tumors: Patients should be referred to an endocrinologist for further evaluation if serum calcitonin is measured and found to be elevated or thyroid nodules are noted on physical examination or neck imaging.
- Pancreatitis: Acute pancreatitis, including fatal and nonfatal hemorrhagic or necrotizing pancreatitis, has been observed in patients treated with Victoza® postmarketing. Observe patients carefully for signs and symptoms of pancreatitis (persistent severe abdominal pain, sometimes radiating to the back with or without vomiting). If pancreatitis is suspected, Victoza® should promptly be discontinued and appropriate management should be initiated. If pancreatitis is confirmed, Victoza® should not be restarted.
- Never Share a Victoza® Pen Between Patients, even if the needle is changed. Pen-sharing poses a risk for transmission of blood-borne pathogens.
- Hypoglycemia: Adult patients receiving Victoza® in combination with an insulin secretagogue (eg, sulfonylurea) or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia. In pediatric patients 10 years of age and older, the risk of hypoglycemia was higher with Victoza® regardless of insulin and/or metformin use.
- Renal Impairment: Acute renal failure and worsening of chronic renal failure, which may sometimes require hemodialysis, have been reported postmarketing, usually in association with nausea, vomiting, diarrhea, or dehydration. Use caution when initiating or escalating doses of Victoza® in patients with renal impairment.
- Hypersensitivity Reactions: There have been postmarketing reports of serious hypersensitivity reactions (e.g., anaphylactic reactions and angioedema) in patients treated with Victoza®. If a hypersensitivity reaction occurs, discontinue Victoza®; treat promptly per standard of care, and monitor until signs and symptoms resolve. Do not use in patients with a previous hypersensitivity reaction to Victoza®. Anaphylaxis and angioedema have been reported with other GLP-1 receptor agonists. Use caution in a patient with a history of anaphylaxis or angioedema with another GLP-1 receptor agonist because it is unknown whether such patients will be predisposed to these reactions with Victoza®.
- Acute Gallbladder Disease: Acute events of gallbladder disease such as cholelithiasis or cholecystitis have been reported in GLP-1 receptor agonist trials and postmarketing. In the LEADER trial, 3.1% of Victoza®-treated patients versus 1.9% of placebo-treated patients reported an acute event of gallbladder disease, such as cholelithiasis or cholecystitis. If cholelithiasis is suspected, gallbladder studies and appropriate clinical follow-up are indicated.
Adverse Reactions
- The most common adverse reactions, reported in ≥5% of patients treated with Victoza® and more commonly than in patients treated with placebo, are nausea, diarrhea, vomiting, decreased appetite, dyspepsia, and constipation. Immunogenicity-related events, including urticaria, were more common among Victoza®-treated patients (0.8%) than among comparator-treated patients (0.4%) in clinical trials.
Drug Interactions
- Victoza® causes a delay of gastric emptying and has the potential to impact the absorption of concomitantly administered oral medications. Caution should be exercised when oral medications are concomitantly administered with Victoza®.
- When initiating Victoza®, consider reducing the dose of concomitantly administered insulin secretagogues (such as sulfonylureas) or insulin to reduce the risk of hypoglycemia.
Use in Specific Populations
- The safety and effectiveness of Victoza® have not been established in pediatric patients less than 10 years of age.
- Victoza® slows gastric emptying. Victoza® has not been studied in patients with pre-existing gastroparesis.
- Victoza® should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Important Safety Information for Ozempic® (semaglutide) injection
WARNING: RISK OF THYROID C-CELL TUMORS
- In rodents, semaglutide causes dose-dependent and treatment-duration-dependent thyroid C-cell tumors at clinically relevant exposures. It is unknown whether Ozempic® causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans as human relevance of semaglutide-induced rodent thyroid C-cell tumors has not been determined.
- Ozempic® is contraindicated in patients with a personal or family history of MTC and in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Counsel patients regarding the potential risk for MTC with the use of Ozempic® and inform them of symptoms of thyroid tumors (eg, a mass in the neck, dysphagia, dyspnea, persistent hoarseness). Routine monitoring of serum calcitonin or using thyroid ultrasound is of uncertain value for early detection of MTC in patients treated with Ozempic®.
Indications and Limitations of Use
Ozempic® (semaglutide) injection 0.5 mg, 1 mg, or 2 mg is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus and to reduce the risk of major adverse cardiovascular (CV) events (CV death, nonfatal myocardial infarction, or nonfatal stroke) in adults with type 2 diabetes mellitus and established CV disease.
- Ozempic® has not been studied in patients with a history of pancreatitis. Consider other antidiabetic therapies in patients with a history of pancreatitis.
- Ozempic® is not indicated for use in patients with type 1 diabetes mellitus.
Important Safety Information cont.
Contraindications
- Ozempic® is contraindicated in patients with a personal or family history of MTC or in patients with MEN 2, and in patients with a hypersensitivity reaction to semaglutide or to any of the excipients in Ozempic®. Serious hypersensitivity reactions including anaphylaxis and angioedema have been reported with Ozempic®.
Warnings and Precautions
- Risk of Thyroid C-Cell Tumors: Patients should be referred to an endocrinologist for further evaluation if serum calcitonin is measured and found to be elevated or thyroid nodules are noted on physical examination or neck imaging.
- Pancreatitis: Acute and chronic pancreatitis have been reported in clinical studies. Observe patients carefully for signs and symptoms of pancreatitis (persistent severe abdominal pain, sometimes radiating to the back with or without vomiting). If pancreatitis is suspected, discontinue Ozempic® promptly, and if pancreatitis is confirmed, do not restart.
- Diabetic Retinopathy Complications: In a 2-year trial involving patients with type 2 diabetes and high cardiovascular risk, more events of diabetic retinopathy complications occurred in patients treated with Ozempic® (3.0%) compared with placebo (1.8%). The absolute risk increase for diabetic retinopathy complications was larger among patients with a history of diabetic retinopathy at baseline than among patients without a known history of diabetic retinopathy.
Rapid improvement in glucose control has been associated with a temporary worsening of diabetic retinopathy. The effect of long-term glycemic control with semaglutide on diabetic retinopathy complications has not been studied. Patients with a history of diabetic retinopathy should be monitored for progression of diabetic retinopathy. - Never Share an Ozempic® Pen Between Patients: Ozempic® pens must never be shared between patients, even if the needle is changed. Pen-sharing poses a risk for transmission of blood-borne pathogens.
- Hypoglycemia: Patients receiving Ozempic® in combination with an insulin secretagogue (eg, sulfonylurea) or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia. Inform patients using these concomitant medications of the risk of hypoglycemia and educate them on the signs and symptoms of hypoglycemia.
- Acute Kidney Injury: There have been postmarketing reports of acute kidney injury and worsening of chronic renal failure, which may sometimes require hemodialysis, in patients treated with GLP-1 receptor agonists. Some of these events have been reported in patients without known underlying renal disease. A majority of the reported events occurred in patients who had experienced nausea, vomiting, diarrhea, or dehydration. Monitor renal function when initiating or escalating doses of Ozempic® in patients reporting severe adverse gastrointestinal reactions.
- Hypersensitivity: Serious hypersensitivity reactions (eg, anaphylaxis, angioedema) have been reported in patients treated with Ozempic®. If hypersensitivity reactions occur, discontinue use of Ozempic®; treat promptly per standard of care, and monitor until signs and symptoms resolve. Use caution in a patient with a history of angioedema or anaphylaxis with another GLP-1 receptor agonist.
- Acute Gallbladder Disease: Acute events of gallbladder disease such as cholelithiasis or cholecystitis have been reported in GLP-1 receptor agonist trials and postmarketing. In placebo-controlled trials, cholelithiasis was reported in 1.5% and 0.4% of patients treated with Ozempic® 0.5 mg and 1 mg, respectively, and not reported in placebo-treated patients. If cholelithiasis is suspected, gallbladder studies and appropriate clinical follow-up are indicated.
Adverse Reactions
- The most common adverse reactions, reported in ≥5% of patients treated with Ozempic® are nausea, vomiting, diarrhea, abdominal pain, and constipation.
Drug Interactions
- When initiating Ozempic®, consider reducing the dose of concomitantly administered insulin secretagogue (such as sulfonylureas) or insulin to reduce the risk of hypoglycemia.
- Ozempic® causes a delay of gastric emptying and has the potential to impact the absorption of concomitantly administered oral medications, so caution should be exercised.
Use in Specific Populations
- There are limited data with semaglutide use in pregnant women to inform a drug-associated risk for adverse developmental outcomes. Discontinue Ozempic® in women at least 2 months before a planned pregnancy due to the long washout period for semaglutide.
