Weight loss is a common goal for millions of people worldwide, and using a prescription weight loss aid in this process has been gaining popularity. When exploring medications for chronic weight management, Ozempic and Saxenda are two prominent options. This comprehensive analysis will delve into their mechanisms of action, effectiveness, administration, side effects, and pricing in Canada.
How Do Saxenda and Ozempic Work?
Saxenda and Ozempic target different mechanisms in the body to promote weight loss, making them suitable for specific individuals
What Is Ozempic?
Ozempic is a prescription medication that contains the active ingredient semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist. It was originally approved by Health Canada for treating type 2 diabetes, though it has shown promising effectiveness for its role in weight loss and blood sugar control.
Ozempic mimics a naturally occurring hormone that regulates appetite and blood sugar. By binding to GLP-1 receptors, it slows down stomach emptying, making you feel fuller for longer and reducing appetite. By slowing down digestion and promoting a feeling of fullness, it can help reduce overall calorie intake and, in turn, lead to weight loss. Additionally, it can improve blood sugar control, making it a dual-purpose medication for those dealing with both type 2 diabetes and weight issues.
What is Saxenda?
Saxenda is a prescription medication that contains the active ingredient liraglutide, another GLP-1 receptor agonist. Saxenda primarily acts on receptors in the brain to reduce appetite and increase feelings of fullness. It’s FDA-approved specifically for chronic weight management and is not primarily used for blood sugar control in diabetics.
Saxenda is typically prescribed for individuals with a body mass index (BMI) of 30 or higher (considered obese) or for those with a BMI of 27 or higher who also suffer from conditions like high blood pressure, type 2 diabetes, or high cholesterol.
Key Differences Between Ozempic and Saxenda
Although both Ozempic and Saxenda are GLP-1 receptor agonists, several differences could influence your decision when choosing the right medication for your weight loss journey.
- Primary Indications: Ozempic is primarily indicated for type 2 diabetes management, although it’s also prescribed off-label for weight loss. Saxenda, on the other hand, is FDA-approved for chronic weight management.
- Dosing: Ozempic is usually administered once a week, while Saxenda requires daily injections, which might be less convenient but allows for consistent daily weight management.
Which is More Effective for Weight Loss - Saxenda or Ozempic?
Both Ozempic and Saxenda have proven to be effective in promoting weight loss, but individual factors will influence the best choice for your weight loss journey.
- Appetite Control: Both Ozempic and Saxenda help suppress appetite, which can result in lower calorie intake. When your body feels fuller for longer periods, you naturally eat less, leading to weight loss over time.
- Slow Digestion: One key function of GLP-1 receptor agonists is their ability to slow the emptying of the stomach. This means food stays in your stomach longer, prolonging the feeling of fullness and reducing hunger.
- Lower Blood Sugar Levels: For people who are managing diabetes in addition to weight loss, Ozempic, in particular, helps improve blood sugar control, making it an ideal choice for people managing type 2 diabetes in addition to weight loss. While Saxenda also mildly affects blood sugar, it’s less impactful compared to Ozempic.
- Reducing High Blood Pressure: Obesity is often associated with high blood pressure, and losing weight with either Ozempic or Saxenda can have a positive effect on your cardiovascular health. Lowering body weight often leads to a reduction in high blood pressure, decreasing the risk of heart disease, stroke, and other complications.
- Cardiovascular Health: Losing weight with either medication can lead to a reduction in high blood pressure, which may lower the risk of major cardiovascular events such as heart disease or stroke. Both drugs have the potential to improve cardiovascular health, though Ozempic's additional impact on blood sugar makes it particularly beneficial for those with both diabetes and weight concerns.
Overall, both medications are effective for weight loss and weight management. The right one will depend on goals, health, and medical needs.
Administration of Ozempic and Saxenda
Both are administered as prefilled pens, through subcutaneous injections (under the skin). However, the biggest difference is the frequency of injection; Ozempic is injected once weekly, while Saxenda is injected once daily. The injection site can be in the abdomen, thigh, or upper arm.
Tips for Administering Saxenda and Ozempic
- Injection Site Rotation: To avoid skin irritation, rotate the injection site each time you inject. For example, if you injected into your abdomen today, use your thigh or upper arm the next time.
- Needle Disposal: Always use a new needle for each injection, and safely dispose of used needles in a sharps container.
- Storage: Both medications should be stored in the refrigerator but can be kept at room temperature for a limited time (Ozempic for 56 days, Saxenda for 30 days) once they’ve been opened. Avoid storing them in extreme temperatures or in direct sunlight.
Side Effects of Saxenda and Ozempic
Both medications come with side effects. It’s essential to consult with your healthcare provider to determine whether these medications are suitable for your personal health and chronic weight management goals.
Common Side Effects
- Abdominal pain: Many users report some level of abdominal discomfort when starting either medication. This can range from mild bloating to more severe cramping.
- Nausea: This is one of the most commonly reported side effects for both Ozempic and Saxenda, especially when first starting the medication. However, the nausea usually subsides after the body adjusts to the drug.
- Low blood sugar (Hypoglycemia): While more common with Ozempic (due to its use for diabetes), both medications can lead to low blood sugar, especially if combined with other medications that lower blood glucose.
- Diarrhea or constipation: Digestive issues can occur, particularly when first beginning treatment. Both medications slow down digestion, which can lead to either diarrhea or constipation depending on how your body reacts.
Serious Side Effects
Unfortunately, in some cases, these weight loss medications can lead to more serious side effects:
- Pancreatitis: Inflammation of the pancreas has been reported with both medications. Symptoms include severe abdominal pain, vomiting, and fever, which should prompt immediate medical attention.
- Gallbladder problems: Weight loss can sometimes lead to the formation of gallstones, and both medications have been linked to an increased risk of gallbladder issues. Symptoms include severe pain in the upper right abdomen, especially after eating a fatty meal.
- Kidney issues: Dehydration from vomiting or diarrhea can stress the kidneys, potentially leading to kidney damage if not managed properly.
Ozempic and Saxenda Pricing in Canada
Price can be a significant factor in choosing between Ozempic and Saxenda. Here’s a general guide to their pricing:
- Dosage: Higher dosages can lead to higher costs.
- Pharmacy: Prices may vary between pharmacies, prices also vary between online pharmacies and retail pharmacies.
- Online weight loss clinics: Some new healthcare companies, like Felixforyou, Livewell, Science and Humen, and DooU, offer Ozempic prices ranging from $320/ box to $280/box. Saxenda can be more expensive, with treatment cost varying from $315/box to $630, depending on insurance coverage
- Insurance Coverage: Your insurance may not cover the cost of this medication for the weight loss program.

- Exploring Generic Options: If available, generics might offer cost savings.
Can Saxenda and Ozempic Be Combined?
It’s important to consult with a healthcare provider when considering combining medications for your weight loss journey. Although they both assist with weight loss and appetite control, combining them with other drugs might increase the risk of side effects like low blood sugar or gastrointestinal issues. Both medications are GLP-1 receptor agonists, and combining them could lead to excessive stimulation of GLP-1 receptors. Always discuss your full medical history and current medications with your doctor to avoid potential interactions.
Switching Between Ozempic and Saxenda
Switching between medications should be done under the guidance of a healthcare provider. Individual responses can vary, and switching might not be necessary or beneficial. Factors such as your individual needs, goals, and response to the medication can influence the decision to switch.
Conclusion
Both Ozempic and Saxenda offer significant benefits for those seeking chronic weight management. While Ozempic has the added advantage of blood sugar control for people with diabetes, Saxenda is specifically approved for long-term weight management. The choice between them should be based on your health goals, personal preferences, and medical advice. Always consult with a healthcare provider to determine which medication is right for your weight loss journey and overall health.
