Ozempic and Victoza are brand-name prescription drugs for the treatment of type 2 diabetes commonly taken with metformin to achieve glycemic control. They also help lower your risk for heart attack, stroke, and death from heart disease. Ozempic and Victoza are both manufactured by Novo Nordisk.
It is not always easy to know how these medications work and the differences between them. Your doctor will prescribe you the most appropriate medication for your needs, but it is still important to better understand the diabetes drugs available to you and their possible side effects.
Both Ozempic and Victoza are injectable type 2 diabetes medications approved by the Food and Drug Administration (FDA). But are they the same? Here we focus on Ozempic vs Victoza and explain clearly and simply what they are, how they work, and the similarities and differences between them.
Ozempic and Victoza belong to a drug class called GLP-1 (glucagon-like peptide-1) receptor agonists. When you eat and drink, your body produces digestive hormones called incretins. GLP-1 is one of these incretin hormones.
GLP-1 incretin hormones help lower your blood glucose levels when you digest food in three ways. They:
Ozempic and Victoza act in the same way as GLP-1 incretin hormones. By stimulating the same receptors, they cause your body to release more insulin, less glucagon, and digest food slower.
Victoza and Ozempic are more active when you have consumed food and are digesting it. They become less active when you stop eating or drinking. They help to ensure your blood glucose levels do not fall too low causing hypoglycemia. Victoza and Ozempic can not be used to treat type 1 diabetes.
Unlike many other treatments for type 2 diabetes, Ozempic (semaglutide) and Victoza (liraglutide) are not types of insulin. They are human hormones that act on different parts of your body. Semaglutide and liraglutide encourage your pancreas to produce more insulin, helping to lower your blood sugar after you’ve eaten. They also appear to increase the growth of the cells in your pancreas that produce insulin (beta-cells).
So, what is the difference between Ozempic and Victoza? Both are GLP-1 receptor agonist medications used to treat type 2 diabetes. They are given as an injection under the skin (subcutaneous injection) using a self-injecting pen device, and they work in the same way. Although Ozempic and Victoza are similar, there are key differences between them.
The active ingredients they contain are the most important difference between them. Ozempic contains a GLP-1 receptor agonist called semaglutide, while Victoza contains a GLP-1 receptor agonist called liraglutide. Semaglutide and liraglutide do work in similar ways, but they are not identical and you may respond to them differently.
Ozempic can be used in adults 18 years and older, and Victoza can be used in adults and children 10 years and older.
The doses prescribed for each drug also vary. Ozempic pens can be prescribed in 0.25 mg, 0.5 mg, and 1 mg doses, whereas Victoza pens can be prescribed in a pre-filled, multi-dose pen that delivers 0.6 mg, 1.2 mg, or 1.8 mg doses.
The frequency of Ozempic and Victoza dosing differs. Ozempic is a weekly semaglutide injection and Victoza is a daily liraglutide injection.
Both Ozempic and Victoza are proven and effective treatments for type 2 diabetes. However, in the SUSTAIN 10 clinical trial that compared the two medications, semaglutide was found to be superior to liraglutide in reducing HbA1c and body weight. The safety profiles were generally similar, except for higher rates of gastrointestinal adverse effects seen with semaglutide than liraglutide.
The study was an open-label trial with 577 adults with type 2 diabetes. The primary endpoint was changed in HbA1c (hemoglobin A1c) from baseline to week 30. The secondary endpoint was body weight changes from baseline to week 30. Mean HbA1c (baseline 8.2%) decreased by 1.7% with semaglutide and 1.0% with liraglutide. The A1c test gives us information on how good your blood sugar level control has been over a period of 3 months. An A1c value of 7% is the general goal for diabetic adults but can differ depending on age and other factors. If treatment is working this A1c test should show improvement. See our blog on What are normal blood glucose levels?
Although Ozempic was found to be more effective than Victoza, it is important to note that people respond to medications differently. This means some people will get better results from Victoza and some from Ozempic. If you’d like to read more about how each drug performed in studies, see the prescribing information for Ozempic and Victoza.
The American Diabetes Association (ADA) recommends using a glucagon-like peptide-1 (GLP-1) agonist, such as Ozempic or Victoza, in adults with type 2 diabetes who also have cardiovascular disease or kidney disease.
Ozempic and Victoza are injected in the same way. You need to inject under your skin (subcutaneous injection) rather than into a vein or muscle. The fatty tissue just under your skin is the ideal place for the drug to be absorbed gradually. If you inject it deeper into your muscle your body will absorb it too quickly. The effects may not last long and will additionally be more painful. Judging the depth correctly can be quite difficult, particularly if you are slim but it is important to master the technique to stay safe.
The injection sites are the thigh, abdomen, or upper arm, these areas are likely to have enough body fat to allow you to easily inject. The importance of rotating injection sites should be noted to maintain effective drug absorption and prevent problems.
Ozempic and Victoza both belong to the same class of medication hence, they both have similar common gastrointestinal side effects such as:
In rare instances, Ozempic and Victoza can cause more serious side effects, including:
For medical advice about side effects, talk with your health care provider and also read the medication guide and instructions for use, that comes with Ozempic and Victoza. You are encouraged to report the negative side effects of prescription drugs to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.
It is most important to realize if diabetes is not treated correctly, it can seriously affect your body. The first thing to remember is you can treat many of the possible problems from diabetes. Unquestionably treatment is most effective when complications are picked up early. Therefore attending regular checkups is vital.
Two types of complications can occur. Firstly, short-term complications (also known as acute) that occur rapidly in the body e.g. hypoglycemia. Secondly, long-term complications (also known as chronic) that take time to develop due to uncontrolled diabetes. Extensive studies in the US (the Diabetes Control and Complications Trial) have shown that any improvement in blood glucose control will reduce your risk of developing complications.
If Ozempic or Victoza are not working well for you speak to your doctor to avoid complications.
Ozempic and Victoza have a boxed warning by the FDA for thyroid cancer risk including medullary thyroid carcinoma (MTC). This was shown in rodent studies but it is unknown whether this can occur in humans. Patients with a history or family history of thyroid cancer, MTC, or multiple endocrine neoplasia syndrome type 2 (MEN 2) should not take Ozempic or Victoza.
MTC can start as a lump in the throat, cause voice hoarseness, or windpipe pipe blockage.
Ozempic and Victoza delay stomach emptying, and the absorption of oral medications may be affected if taken at the same time. It is important to discuss with your healthcare provider the timing of your medications. Narrow therapeutic index drugs should especially be monitored. These include drugs with a small window between therapeutic effect and toxicity such as Coumadin (warfarin), Lanoxin (digoxin), and seizure medications.
Don’t take Ozempic or Victoza if you:
Talk to your doctor before taking Ozempic or Victoza if you:
Always speak to your healthcare provider for medical advice regarding drug interactions, taking supplements, taking over-the-counter medications, and drinking alcohol when using Ozempic or Victoza. Healthcare professionals are the most reliable and accurate source of drug information.
Yes, but it is strongly recommended by healthcare professionals to avoid alcohol if you have diabetes. Alcohol interacts with diabetes medications causing low blood sugar (hypoglycemia). When you drink alcohol your liver will choose to remove the alcohol in your body over maintaining your blood sugar level leading to hypoglycemia. Low blood sugar makes you drowsy, confused and makes walking difficult, which are also the signs of being drunk. The confusion of being drunk or hypoglycemic can be very unsafe, and a low sugar episode could go unnoticed if you are drunk. Moderate amounts of alcohol may cause blood sugar to rise but excessive alcohol can actually decrease your blood sugar levels.
The American Diabetes Association recommends you ask yourself three questions before drinking alcohol with diabetes:
Ozempic and Victoza are both GLP-1 receptor agonist medications used to treat type 2 diabetes mellitus. Although similar, they are different medications that contain different active ingredients. Semaglutide in Ozempic and liraglutide in Victoza. The two medications may also affect you differently.
Victoza belongs to a class of Type 2 diabetes medications called GLP-1 receptor agonists. Other GLP-1 receptor agonists include Bydureon, Byetta, Trulicity (dulaglutide), Rybelsus (oral medication of Ozempic), Wegovy (indicated for weight management), and Saxenda (same active drug as Victoza used for weight loss in obesity treatment)
Ozempic begins working as soon as you take it. It can take 5 to 8 weeks before you see a noticeable drop in your blood glucose and up to 6 months for it to be most effective. Ozempic should be taken alongside changes to your diet and exercise. You will get better results faster if you stick to your diet and exercise program.
Victoza can be taken over the long term. It is important to note that you may need to stop using Victoza if it causes you severe side effects, or if it does not work effectively for you.
