Ozempic vs Saxenda
Introduction
For patients with type 2 diabetes or those struggling with weight management, certain medications that modify the body's insulin response and appetite can be beneficial. Ozempic and Saxenda are two such drugs commonly used in these scenarios. Both drugs belong to a class known as glucagon-like peptide-1 (GLP-1) agonists, which mimic the effects of natural hormones to lower blood sugar levels.
Ozempic is primarily prescribed for managing blood glucose levels in adults diagnosed with type 2 diabetes who do not achieve adequate control through diet and exercise alone. It assists by mimicking GLP-1 hormone activity that stimulates insulin production after meals, suppressing excessive glucagon secretion thus helping regulate blood sugar spikes.
Saxenda, on the other hand, is primarily utilized for chronic weight management in adults classified as obese or overweight with at least one weight-related condition like high blood pressure or type 2 diabetes. It works similarly by enhancing satiety - creating a sense of fullness after meals - thereby reducing food intake and promoting weight loss.

What is Ozempic?
Semaglutide (the generic name for Ozempic) is a glucagon-like peptide-1 receptor agonist which represents a new class of drugs used in the treatment of type 2 diabetes, and it was first approved by the FDA in 2017. Ozempic works by imitating an intestinal hormone that targets several areas in the body to naturally increase insulin levels when needed and decrease the amount of glucose being produced and released by the liver. It's prescribed as part of a comprehensive program including diet changes, exercise, weight control, foot care, eye care, dental hygiene, and regular medical testing.
Liraglutide (the generic name for Saxenda), on the other hand, also belongs to this drug class but was specifically developed as a weight loss medication approved by FDA in 2014. Saxenda still shares similar mechanisms with Ozempic such as reducing hunger sensation but its primary aim is to help overweight or obese adults lose weight. Both have different effects on blood sugar control due to their varying concentrations where Ozempic has more influence than Saxenda resulting in fewer side effects related to hypoglycemia.
What conditions is Ozempic approved to treat?
Ozempic is approved for the treatment of different health conditions:
- Type 2 diabetes as an adjunct to diet and exercise, improving blood sugar levels in adults
- Reducing risk of major cardiovascular events such as heart attack, stroke or death in adults with type 2 diabetes mellitus and established cardiovascular disease.
- Chronic weight management (as an adjunct to a reduced calorie meal plan and increased physical activity) in adult patients who are overweight or obese.
How does Ozempic help with these illnesses?
Ozempic aids in the management of Type 2 diabetes by mimicking the function of a hormone in the body called Glucagon-like peptide-1 (GLP-1). It does this by binding to GLP-1 receptors in the pancreas which stimulates the release of insulin when blood sugar levels are high. Insulin is a hormone that helps regulate blood sugar levels by allowing cells in the body to take in sugar from the bloodstream. This process helps to lower blood sugar levels, thus managing the negative effects of Type 2 diabetes. Furthermore, Ozempic slows the rate at which food leaves the stomach, which can help to decrease the amount of sugar absorbed into the bloodstream after a meal. It's thought that individuals with Type 2 diabetes have relatively lower levels of insulin, or they may have insulin resistance. Therefore, by increasing insulin levels and slowing the absorption of sugar, Ozempic can help patients manage their condition and stabilize their blood sugar levels.
What is Saxenda?
Saxenda is a brand name for liraglutide, which is an injectable glucagon-like peptide-1 receptor agonist that regulates glucose levels in the body by increasing insulin secretion and decreasing glucagon production. It also slows gastric emptying and increases feelings of fullness after meals, thereby helping to control weight. Saxenda was first approved by the FDA in 2014 specifically as a treatment for obesity (for those with a BMI of 30 or more) or overweight patients (with a BMI of at least 27) who have at least one weight-related condition such as hypertension, type 2 diabetes, or high cholesterol.
The role of Saxenda isn't primarily about controlling blood sugar like Ozempic; instead it's chiefly designed to help people lose weight and maintain that loss. Its action on slowing gastric emptying means its side-effect profile can be different from other drugs used for obesity management - mainly gastrointestinal issues such as nausea are common but usually improve over time. The effects on feeling fuller can be beneficial in managing excessive appetite often experienced by individuals struggling with weight problems.
What conditions is Saxenda approved to treat?
Saxenda is authorized for use in the management of the following conditions:
- Chronic weight management in adults with a Body Mass Index (BMI) of 30 or greater (obese), or 27 or greater (overweight) in the presence of at least one weight-related comorbidity such as hypertension, type 2 diabetes mellitus, or dyslipidemia.
- It is also used as an addition to a reduced-calorie diet and increased physical activity in these individuals.
How does Saxenda help with these illnesses?
Saxenda, like Ozempic, is a glucagon-like peptide-1 (GLP-1) receptor agonist that plays crucial roles in many processes within the body, affecting satiety, insulin secretion and gastric emptying. These actions contribute to weight management and improved glycemic control in individuals with type 2 diabetes or obesity. Saxenda works by mimicking the GLP-1 action which reduces hunger and promotes feelings of fullness thereby helping to manage calorie intake. It also aids glucose regulation by enhancing insulin secretion when blood sugar levels are elevated. While both drugs contain similar active ingredients for weight loss purposes, Saxenda is specifically approved for chronic weight management when combined with a reduced-calorie diet and physical activity under the supervision of healthcare providers. Unlike Ozempic which is primarily used as a treatment for type 2 diabetes but may have an added benefit of weight loss.
How effective are both Ozempic and Saxenda?
Both semaglutide (Ozempic) and liraglutide (Saxenda) have established histories of success in treating patients with type 2 diabetes and obesity. They were initially approved by the FDA several years apart, but both fall into a class of drugs called glucagon-like peptide-1 (GLP-1) receptor agonists that stimulate insulin production in response to meals.
The effectiveness of semaglutide and liraglutide was directly compared in a double-blind clinical trial; they showed similar efficacy in managing blood glucose levels as well as weight loss. In this study, none of the different metrics studied to measure efficacy differed substantially between patients receiving Saxenda or Ozempic.
A review on liraglutide demonstrated its effectiveness in controlling blood glucose levels starting from the early stages of treatment, showing a favorable safety profile over many other anti-diabetic drugs. It is also well-tolerated among vulnerable populations like elderly individuals or those with kidney disease. Further studies suggest liraglutide has become one of the most widely prescribed GLP-1 receptor agonists worldwide.
In contrast, a recent meta-analysis indicated that semaglutide seems more effective than placebo in aiding significant weight loss along with good glycemic control when used alone or alongside other first-line treatments for type 2 diabetes mellitus such as metformin. Semaglutide can be considered an optimal choice for obese patients who did not respond well to lifestyle modifications or need additional glycemic control without risking hypoglycemia.

At what dose is Ozempic typically prescribed?
Dosage of Ozempic begins at 0.25 mg subcutaneously once per week for the first four weeks, then increases to 0.5 mg once per week. If additional blood sugar control is needed, after at least four weeks, the dosage can be increased to a maximum of 1 mg once per week. On the other hand, Saxenda's starting dose is also 0.6 mg subcutaneously daily for one week; this should be increased weekly by increments of 0.6 mg until a maintenance dose of 3 mg/day is reached in five weeks time based on patient tolerance and need for weight loss efficacy—the maximum daily dosage that should not be exceeded.
At what dose is Saxenda typically prescribed?
Saxenda treatment is typically initiated at a dosage of 0.6 mg/day, injected subcutaneously. The dose can then be gradually increased by 0.6 mg increments each week until the recommended maintenance dose of 3 mg/day is reached. This titration strategy helps to reduce gastrointestinal side effects and should be divided into daily doses, using a pre-filled injection pen. If patients do not respond adequately to the maximum daily dosage after several weeks, discontinuation of Saxenda should be considered as its effectiveness may not improve with continued administration.
What are the most common side effects for Ozempic?
Common side effects of Ozempic include:
- Nausea
- Vomiting
- Diarrhea
- Stomach pain
- Loss of appetite
- Dizziness
Saxenda, on the other hand, shares many similar side effects but also includes:
- Hypoglycemia (low blood sugar)
- Insomnia
- Constipation
- Gallbladder disease Increased heart rate.
Both can potentially cause changes in kidney function and should be used under supervision of a healthcare provider. As with any medication, if you experience any severe or persistent symptoms while taking these drugs, seek medical attention immediately.
Are there any potential serious side effects for Ozempic?
While Ozempic and Saxenda are both injectable medications used for weight management, their potential side effects can differ. Some serious but rare side effects of Ozempic include:
- Signs of severe allergic reactions: hives, difficulty breathing or swallowing, swelling in your face, lips, tongue or throat.
- Possible thyroid tumors including cancer: symptoms may include a lump in the neck, shortness of breath, persistent coughing and difficulty swallowing.
- Pancreatitis – inflammation of the pancreas: signs such as severe stomach pain that might spread to your back with or without vomiting should be taken seriously.
- Diabetic retinopathy complications (changes to your vision) which could cause vision loss if left untreated.
Likewise for Saxenda:
- Thoughts about suicide or dying; attempts to commit suicide; new or worse depression; new anxiety; feeling agitated -or restless.
- Serious allergic reactions like skin rash, itching/swelling especially on face/tongue/throat causing severe dizziness and trouble breathing.
If you experience any unusual symptoms while taking either one of these drugs it’s important to seek medical attention right away.
What are the most common side effects for Saxenda?
With Saxenda, a variety of side effects can occur. These may include:
- Nausea and vomiting
- Diarrhea or constipation
- Decreased appetite, leading to weight loss
- Dizziness or lightheadedness
- Dry mouth, belching or indigestion
- Fatigue and weakness
- Disturbance in sleep patterns (insomnia)
- Increased heart rate
- Mild rash on the skin
- Headache or migraine attacks These symptoms are generally temporary and tend to improve with time as your body adjusts to the medication. If you notice any unusual changes in your health condition while taking this drug, it's essential to consult with your healthcare provider immediately.
Are there any potential serious side effects for Saxenda?
Saxenda, like any other medication, can potentially cause side effects. It is important to be aware of these in order to know when you need to seek medical attention. If the following symptoms occur after taking Saxenda, please contact your healthcare provider immediately:
- Signs of an allergic reaction such as hives; difficulty breathing; swelling in your face, lips, tongue or throat
- Severe pain in your upper stomach spreading to your back (pancreatitis)
- Rapid heart rate
- Increased thirst and urination
- Sudden behavioral changes or thoughts about hurting yourself
- Feeling jittery or nervous
- Lightheadedness or dizziness Remember that it's crucial to monitor how you're feeling while on this medication and report any concerning symptoms promptly.
Contraindications for Ozempic and Saxenda?
Both Ozempic and Saxenda, much like many other injectable medications, may lead to side effects in some individuals. If you notice any serious adverse reactions such as pancreatitis symptoms (severe abdominal pain that won't go away and may reach your back with or without vomiting), or thyroid tumors (a lump in the neck, hoarseness, trouble swallowing or shortness of breath), please seek immediate medical attention.
Neither Ozempic nor Saxenda should be used if you have a personal or family history of medullary thyroid carcinoma (MTC) or Multiple Endocrine Neoplasia syndrome type 2. Always tell your physician about all the medications you are taking; certain drugs can interact with Ozempic and Saxenda causing unwanted effects.
People who are using insulin should not use Saxenda due to potential drug interactions. On the other hand, Ozempic is often used together with basal insulin but requires close monitoring by a healthcare professional.
How much do Ozempic and Saxenda cost?
For the brand name versions of these drugs:
- The price of 2 pens (1.5 mg each) of Ozempic averages around $800, which translates to approximately $26–$40 per day, depending on your dose.
- Saxenda is priced at about $1300 for a pack containing 3 pens (18 mg/3ml), working out to roughly $43/day.
Thus, if you are in the higher dosage range for Ozempic (i.e., 1.5 mg/day or more), then branded Saxenda could be less expensive on a per-day treatment basis. Please note that cost should not be your primary consideration in determining which drug is appropriate for you.
However, it's important to note that there are currently no generic equivalents available for either Ozempic (semaglutide) or Saxenda (liraglutide). Both medications can only be purchased under their respective brand names and as such costs remain high across both options.
Popularity of Ozempic and Saxenda
Semaglutide, marketed as Ozempic, is a medication used for the treatment of type 2 diabetes. In 2020, it was estimated that about 1 million people in the US were prescribed this drug. Semaglutide accounted for nearly 10% of glucagon-like peptide-1 receptor agonist prescriptions in the US and has been steadily increasing since its approval by FDA in December 2017.
On the other hand, Liraglutide or Saxenda is primarily prescribed for chronic weight management alongside a reduced-calorie diet and increased physical activity. It received authorization from FDA for use as an obesity-treatment drug in late December 2014. By 2020, around half a million people within the USA were using liraglutide to manage their weight making up approximately just under five percent of overall anti-obesity prescriptions. The prevalence of liraglutide usage has remained steady over recent years.
Conclusion
Both Ozempic (semaglutide) and Saxenda (liraglutide) are injectable medications that can help people manage their weight. They are both classified as glucagon-like peptide-1 receptor agonists, which means they mimic the action of GLP-1, a hormone that regulates blood sugar levels and slows digestion. Both drugs have been proven to be effective in clinical studies for the management of obesity when combined with diet and exercise.
While both drugs work similarly, there is a primary difference in their approved uses: Ozempic is primarily used to improve glycemic control in adults with type 2 diabetes as part of an overall treatment plan including diet and exercise; whereas Saxenda's main use is long-term weight management for those who are overweight or obese.
Both medications do not have generic versions available yet, which may impact cost considerations especially for out-of-pocket payers. In terms of side effects, common ones include nausea, diarrhea, vomiting and constipation – these tend to be transient though may require medical consultation if severe or persistent. Uncommon but more serious risks associated with these medicines include pancreatitis and thyroid tumors; hence patients should discuss potential benefits versus risks thoroughly with their healthcare providers.
