Ozempic and Victoza are two injectable medications commonly prescribed for people with type 2 diabetes. Although they contain different active ingredients, both belong to the same class of drugs known as GLP-1 agonists.While neither Ozempic nor Victoza has been officially approved for weight loss, they do promote weight reduction and are sometimes used off-label to manage obesity.
In addition to their differing active ingredients, Ozempic and Victoza vary in terms of dosage and efficacy, as evidenced by clinical trials.
This article explores what sets these two drugs apart, examining their weight loss benefits, administration methods, dosages, potential side effects, and more.
What Is Ozempic and How Does It Work?
Ozempic belongs to the group of GLP-1 agonist drugs and contains semaglutide, an active ingredient that mimics a naturally occurring hormone in the body. The injectable medication is prescribed to treat patients with type 2 diabetes and reduce the risk of developing cardiovascular complications.
Ozempic has taken everyone by storm for its off-label weight loss benefits. This is primarily due to the way semaglutide interacts with the body, aiding patients with obesity in managing their weight more efficiently. Another brand name, Wegovy, also contains the same active ingredient and is FDA-approved specifically for weight loss.
Here is how semaglutide works:
- Mimics the GLP-1 hormone: Semaglutide belongs to the GLP-1 hormone class that is naturally found in the body. The hormone is released in the gut in response to eating. Hence, it not only regulates the appetite but also the blood sugar.
- Produces more insulin: The GLP-1 hormone promotes the body to produce more insulin when released. This helps reduce glucose in the bloodstream, especially after eating.
- Suppresses appetite: When in high amounts, GLP-1 interacts with the brain, lowering the appetite and signaling that you are full. Hence, when taking Ozempic, patients tend to feel less hungry, and when combined with diet and exercise, they can lose a substantial amount of weight.
- Slows down digestion: Ozempic promotes a feeling of fullness, making you less likely to eat throughout the day. This effect is due to the medication delaying stomach emptying.
What Is Victoza and How Does It Work?
Victoza is another injectable medication prescribed to treat type 2 diabetes. It has been approved by the FDA to aid in lowering cardiovascular problems in people with diabetes and heart disease.
Its active ingredient is liraglutide, and the medication belongs to the GLP-1 agonist class, just like Ozempic. Despite the differences in ingredients, Victoza gained popularity not only for its ability to lower blood sugar but also for its assistance with weight loss.
Another medication that comes with liraglutide is Saxenda, a brand-name drug that has been approved by the FDA to help with weight loss.
Here is how liraglutide interacts with the body:
- Acts like the hormone GLP-1: Victoza mimics a naturally occurring hormone that is released from the small intestine after taking a meal.
- Releases more insulin: The medication helps the pancreas produce more insulin, hence controlling the blood sugar.
- Slows digestion: When taking Victoza, the GLP-1 hormone slows stomach emptying, keeping food for longer and suppressing appetite. By feeling fuller, you are less likely to eat a lot during the day.
Ozempic vs. Victoza: Key Differences
Despite Ozempic and Victoza containing different active ingredients, their purposes seem to overlap. Both medications control the glucose levels in the blood but also promote weight loss benefits.
Both medications are also FDA-approved for treating type 2 diabetes but are sometimes prescribed for weight loss at the discretion of a healthcare provider.
There are two key differences between Ozempic and Victoza, and they are:
Usage
Ozempic and Victoza are both injected under the skin to regulate blood sugar levels. What sets these two medications apart is that Victoza, unlike Ozempic, is approved for children aged 10 years and older.
Dosage
Although Ozempic and Victoza are two injectables, their dosages and frequency slightly differ. Here is a table comparing the dosages of two medications:
| Victoza | Ozempic | |
| Form | Subcutaneous injection | Subcutaneous injection |
| Strength | 6 mg/mL | 2 mg/3 mL |
| Dose | 0.6 mg | 0.5 mg |
Patients who start using Ozempic typically inject the smallest dosage weekly. Once the body adjusts to the medication, the dosage is gradually increased per your doctor’s recommendations.
Victoza, on the other hand, is injected daily. Each pen lasts for a month, depending on the dose you use.
What both medications have in common is that both are injected under the skin and can be taken either before or after taking a meal.
Ozempic vs. Victoza: Efficacy and Results
Ozempic and Victoza haven’t been compared long-term, yet there are separate trials that examined the medications and their efficacy. Researchers have concluded that semaglutide (the active ingredient in Ozempic) might be more effective than liraglutide (the active ingredient in Victoza), especially in long-term blood sugar regulation.
In terms of weight loss, another trial has indicated that Ozempic may be a better choice for weight loss than Victoza. Patients who had been taking Ozempic lost 13 pounds in 30 weeks, compared to 4 pounds with Victoza after the same time period.
However, more comparative research trials are needed to confirm these findings. Remember, your personal health situation may differ from the results shown in the trial. Always consult with your doctor to determine whether Ozempic or Victoza is suitable for you.
Victoza vs. Ozempic: Side Effects
Both Victoza and Ozempic may cause side effects, and it is important to be aware of the potential risks and when to see your doctor.
Common mild side effects of both medications include:
- Nausea
- Vomiting
- Headache
- Diarrhea
- Constipation
- Loss of appetite
Ozampic may have different effects, including abdominal pain and mild allergic reactions.
The mild side effects may be temporary and last for up to a few days.
More serious side effects of Ozempic and Victoza you should always report to your healthcare provider are:
- Inflammation of pancreas
- Low blood sugar
- Diabetic retinopathy
- Kidney problems
- Severe allergic reaction
In case of any serious side effects, immediately contact your doctor.
Victoza vs. Ozempic: Dosage
Ozempic and Victoza are both administered using pre-filled pens, but they differ in dosage and frequency. Your healthcare provider will advise on the appropriate starting dose and when to adjust it.
- Ozempic: Initially, Ozempic is injected weekly at a low dose of 0.25 mg or 0.5 mg. After a few weeks, once the body has adjusted to the medication, the dose may be increased to 1 mg or 2 mg weekly, depending on the desired outcomes.
- Victoza: Victoza is injected daily, starting at a low dose of 0.6 mg. Once the body has acclimated to the medication, the doctor may recommend increasing the dose to 1.2 mg or 1.8 mg.
Ozempic vs. Victoza: Cost
Both Ozempic and Victoza are expensive medications, often difficult to afford, especially without insurance coverage. Additionally, not all insurance plans cover these medications, and those that do may only cover just a portion of the cost.
If you are buying Ozempic or Victoza out of your pocket, you can expect these pieces:
- Ozempic: Approximately $935
- Wegovy: Approximately $1,346

Ozempic vs. Victoza: Which One Is For Me?
Understanding the key differences between Ozempic and Victoza will help you understand which medication suits you better. Here are a few factors to consider when deciding on the best choice:
- Your health needs: If you need to manage type 2 diabetes, alongside weight loss, Ozempic might be the preferred option. It effectively controls both blood sugar levels and aids in losing weight.
- Frequency: Both Ozempic and Victoza are long-term medications, so you should consider your preference for medication frequency. Ozempic is injected once a week, which many people may find more convenient. Victoza, on the other hand, requires daily injections.
- Gastrointestinal side effects: If you are concerned about side effects of Ozempic and Victoza, specifically nausea, vomiting, and diarrhea, Ozempic in low doses may be a better initial choice for you. Remember to consult with your doctor and monitor potential side effects.
- Insurance coverage: Evaluate the cost for both medications and check with your insurance provider whether your plan provides any financial support. You may also check for manufacturer coupons and/or patient assistance programs that can reduce out of pocket expenses.
