Saxenda vs Semaglutide: What’s the Difference? (Pros and Cons)

Saxenda® and semaglutide are two medications that have gained attention in the treatment of obesity, offering potential options for individuals struggling with weight management. Understanding the differences between these drugs is important for making informed decisions about weight loss strategies. Always consult with a healthcare provider before starting any new medication for weight management to ensure it aligns with your health needs and goals.

‍

This article will look at how Saxenda^® and semaglutide work, how effective they are, and what side effects they might have. We'll explore the main differences between these drugs, looking at their good and bad points. This will help people understand which option might work better for them, and they’ll know more about how Saxenda^® and semaglutide are alike and different. 

‍

Key Takeaways

• Saxenda^® and semaglutide are both glucagon-like peptide 1 (GLP-1) agonists used for weight management, but they have distinct FDA approvals ^[1][2].

• Saxenda^® (liraglutide) is FDA-approved for long-term weight management in adults with a BMI of 30 or higher or 27 or higher and at least one weight-related health condition ^[2].

• Semaglutide, marketed as Ozempic^®, is FDA-approved for managing blood sugar in adults with type 2 diabetes and reducing cardiovascular risks. It's often prescribed off-label for weight loss ^[2].

• Both medications are available with a prescription and are administered via subcutaneous injection ^[1].

• Semaglutide has been shown to be more effective in improving blood glucose control and weight loss compared to liraglutide (Saxenda^®) ^[3].

• Both medications work by mimicking the naturally produced hormone GLP-1, but semaglutide has a longer duration of action ^[3].

‍

What Is Semaglutide?

Semaglutide is a synthetic analog of the naturally occurring hormone glucagon-like peptide-1 (GLP-1) [4]. It is part of a class of drugs known as GLP-1 receptor agonists, used primarily for managing type 2 diabetes and, in certain forms, for weight management [4]. It's part of a group of drugs called GLP-1 receptor agonists, known for their ability to help manage type 2 diabetes and lead to weight loss [5]. 

‍

The use of semaglutide for weight loss should be discussed with a healthcare provider to ensure it is appropriate for your specific condition. You need a medical consultation and a prescription from a doctor to get compounded semaglutide for both the injectable form and oral forms. Your doctor will decide if semaglutide is right for you and which type: either the injectable form of semaglutide (Wegovy^®, Ozempic^®) or one of the oral forms of semaglutide (Rybelsus^®, SubMagna™).

‍

If you need a more customized dose or formulation of semaglutide that’s not available in regular prescriptions, compounded semaglutide can be a great option, offering flexibility to meet your specific needs. Talk with your healthcare provider to ensure it’s safe, effective, and sourced from a reputable source like Eden.

‍

Semaglutide works in the body by attaching to and turning on GLP-1 receptors [4]. This activation leads to several effects:

1. It prompts insulin release from pancreatic beta cells when glucose is present.

2. It cuts down glucagon production from pancreatic alpha cells.

3. It empties the stomach more, which helps control blood sugar after eating.

4. In the brain, it curbs hunger, resulting in less calorie intake and possible weight loss [4].

‍

These mechanisms mean semaglutide has an impact on managing blood sugar levels in people with type 2 diabetes and helps weight loss in people who are obese or overweight [5]. New research also points to possible kidney health benefits, with clinical trials showing that semaglutide may lower the risk of serious kidney disease [6].

‍

How Does Semaglutide Work?

Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist that acts like the natural GLP-1 hormone the gut makes [7]. It influences GLP-1 receptors in different body parts, including the gastrointestinal tract, pancreas, and brain [8]. 

‍

When turned on, these receptors cause several effects:

1. Blood Sugar Control: Semaglutide improves how the body releases insulin when glucose levels rise, which helps lower blood sugar after eating [8]. It also decreases the amount of glucagon the body produces, which further helps to control glucose [9].

2. Appetite Regulation: Semaglutide interacts with GLP-1 receptors in the hypothalamus. This has an impact on appetite suppression, food craving reduction, and fullness enhancement [8] [7]. Semaglutide typically begins to suppress appetite within a few days to a week of starting the medication, with more noticeable effects developing over the first few weeks.

3. Slowed Gastric Emptying: Semaglutide impacts stomach emptying, causing a small delay. This helps to control how glucose enters the bloodstream after eating [9].

4. Pancreatic Function: The medication boosts the growth of pancreatic β-cells. This might improve insulin production in the long run [8].

‍

Semaglutide's long-acting nature boosts its effectiveness. Changes to its structure allow it to attach to albumin, which makes it stay in the body longer and protects it from breakdown by the DPP-4 enzyme [8]. This leads to a half-life of about 7 days, so patients need to take it once a week [9].

‍

By copying the body's natural GLP-1 hormone, semaglutide has an impact on blood sugar control and causes weight reduction in people with type 2 diabetes or obesity [10]. Semaglutide comes in pill form, as a sublingual suspension, and as an injection. Each type has its pros and cons, and there are several factors to consider when deciding between semaglutide tablets vs injections. By mimicking a natural hormone that controls hunger and blood sugar, semaglutide tablets work by helping people manage their weight by reducing food cravings.

‍

Following semaglutide safety guidelines will help cut back on possible side effects and help you get the best results as you work toward managing your weight loss.

‍

What Is Saxenda^®?

If you're considering semaglutide alternatives, options like liraglutide (Saxenda^®) or other GLP-1 receptor agonists might be effective for weight management and blood sugar control. It's important to discuss these alternatives with your healthcare provider to determine the best fit for your needs and health goals.

‍

Saxenda^®, an injection you get through a prescription, has liraglutide in it. Doctors use it to help adults and some teens manage their weight [11] [12]. Adults can take it if their Body Mass Index (BMI) shows they're obese (30 or more) or overweight (27 or more) with at least one health problem tied to their weight [11]. Kids between 12 and 17 years old can use Saxenda^® if they're obese and weigh more than 132 pounds (60 kg) [11] [12].

‍

Saxenda^® decreases hunger and slows digestion [13]. Users inject it under the skin with a multi-dose pen [12]. The drug should be used with a low-calorie diet and more exercise [11] [12]. Saxenda^® and Victoza^® contain the same active ingredient (liraglutide), but the FDA has approved them for treating different conditions, and they come in different strengths. Doctors can't prescribe Saxenda^® to treat type 1 or type 2 diabetes [12]. 

‍

Saxenda^® can help you manage your weight, and you should know about its possible side effects. These might include bad allergic reactions, tumors in your thyroid, inflamed pancreas, low sugar in your blood, damage to your kidneys, issues with your gallbladder, and a faster heartbeat [13]. You should talk to your doctor about these risks and tell them right away if you notice any worrying symptoms.

‍

How Does Saxenda^® Work?

Saxenda^® (liraglutide) acts like a glucagon-like peptide-1 (GLP-1) receptor agonist, copying what the natural GLP-1 hormone does in the body [14]. It targets specific parts of the brain and digestive system to help control weight [15].

‍

In the brain, Saxenda^® interacts with neurons in the hypothalamus, an area that plays a role in controlling appetite [15]. This interaction results in a lower appetite and less food intake [15]. By making people feel fuller and less hungry, Saxenda^® helps patients eat fewer calories, which is key to managing weight [15] [16].

‍

Saxenda^® has an influence on the digestive system in several ways:

1. It slows stomach emptying: This helps patients feel full longer after eating [16].

2. It boosts insulin release: When glucose is present, Saxenda^® triggers insulin production [14].

3. It lowers glucagon production: Saxenda^® cuts down on glucagon, a hormone that increases blood sugar levels [14].

‍

Saxenda's^® long-lasting effect comes from its unique structure. A fatty acid molecule attaches to the GLP-1 molecule, which allows it to bind to albumin in the tissue under the skin and in the blood [14]. This binding slows down the breakdown of Saxenda^® and reduces how the body gets rid of it, making it work longer [14].

‍

Saxenda^®, while similar to insulin in managing blood sugar, isn't a type of insulin [16]. It's a GLP-1 agonist working with a low-calorie diet and more exercise to help people lose weight and keep it off [11].

‍

Semaglutide And Saxenda^® Compared

Saxenda^®: Weight Loss Effectiveness

Saxenda^® (liraglutide) affects weight control. Research involving 769 people showed that about half dropped at least 5% of their body weight in six months. Also, 18.3% lost at least 10% [17]. Saxenda^® also helps lower blood pressure and glucose levels in people with diabetes mellitus [17].

‍

Semaglutide: Weight Loss Effectiveness

Clinical studies suggest that semaglutide may lead to greater weight loss compared to Saxenda®. However, individual results may vary, and the choice of medication should be based on a comprehensive evaluation by a healthcare provider. A clinical trial involving 2,000 adults with obesity found that about half of the participants dropped 15% of their body weight in 68 weeks when using semaglutide [17]. Another study reported an average weight change of –15.8% with semaglutide compared to –6.4% with liraglutide [18].

‍

It is important to discuss all potential side effects and benefits with your healthcare provider to determine the best treatment plan for you.

‍

Saxenda^®: Safety

Saxenda^® and semaglutide have similar side effects. These include feeling sick, throwing up, being unable to pass stool, and having loose stools [17]. The drug comes with a clear warning about the chance of getting thyroid cancer [2]. People who take Saxenda^® might have problems with their gallbladder. The drug can slow down how the gallbladder contracts and how food moves through the gut [17].

‍

Semaglutide: Safety

Semaglutide has a safety profile similar to Saxenda^®, but it may cause more side effects [18]. It also comes with a boxed warning about thyroid cancer risk [2]. Some people who use it report ongoing pain in their upper middle or left stomach areas. Lawsuits have claimed it causes stomach paralysis (gastroparesis) [17]. 

‍

​​If you’re wondering how long semaglutide stays in your system, it has a half-life of about a week. This means it can linger in your system for several weeks after you take your final dose. Sticking to semaglutide safety guidelines will help you cut down on possible side effects and get the best results as you work to manage your weight. Talking to your prescriber if you're worried about anything is highly recommended.

‍

Saxenda^®: Cost

Without insurance, Saxenda^® costs about $1,802 for a month's supply [19]. Insurance coverage can make Saxenda^® more budget-friendly [17].

‍

Semaglutide: Cost

The semaglutide costs can add up quickly if your insurance doesn't cover it. Prices can change based on your insurance plan, where you buy the semaglutide, and other factors. Research shows patients might pay up to 68% of the cost themselves for weight loss drugs.

‍

Semaglutide, sold as Ozempic^®, has a price tag of about $935 without insurance for a 0.25 or 0.5 mg dose [17]. Patients with eligible private or commercial insurance might pay out as little as $25 to get up to a three-month supply [17]. 

‍

Semaglutide vs Saxenda^®: Pros And Cons

‍

Semaglutide Pros

Semaglutide has a substantial impact on weight control. Tests show that about half the people in the study shed 15% of their weight in 68 weeks [17]. This drug also lowers blood sugar and cuts the chance of significant heart problems by 20-26% in adults who are overweight or obese [20]. Semaglutide works with GLP-1 receptors in the brain to stop hunger and food cravings [5].

‍

Semaglutide Cons

Semaglutide often causes nausea, vomiting, diarrhea, and constipation [17]. Some people who take it report ongoing pain in their upper middle or left stomach areas. Lawsuits claim it can lead to stomach paralysis (gastroparesis) [17]. The drug comes with a boxed warning about thyroid cancer risk [2]. Users need to inject semaglutide once a week, which some might find a hassle [21].

‍

Saxenda^® Pros

Saxenda^® (liraglutide) shows promising results in helping people lose weight. A study with 769 people found that about half of them dropped at least 5% of their weight in six months [17]. It also helps lower blood pressure and blood sugar levels in people with diabetes [17].

Saxenda^® Cons

Saxenda^®, like semaglutide, has similar side effects. These include feeling sick, throwing up, being unable to pass stool, and having runny stools [17]. It comes with a warning on the box about the chance of thyroid cancer [16]. People who take Saxenda^® might have problems with their gallbladder. It can reduce the gallbladder contract and slow down how food moves through the gut [17]. One big downside of Saxenda^® is how much it costs. Each pen can set you back $1,349 and lasts between 6 to 17 days, depending on how much you need to use [17].

‍

‍

Saxenda^® vs Semaglutide Overall

Saxenda^® (liraglutide) and semaglutide (Ozempic^®) belong to the GLP-1 receptor agonist class of drugs. Doctors prescribe them to manage weight and control blood sugar levels. Although these medications work in similar ways, they differ in how well they work and for what the FDA has approved them.

‍

Saxenda^® has been approved to manage weight in adults. You can use it if your BMI is 30 or above, or 27 or above, with at least one health issue linked to your weight [1]. To get the best results, you need to take it along with eating fewer calories and moving more [1]. Semaglutide, in contrast, comes as a shot that you inject once a week. Doctors prescribe it to treat type 2 diabetes [1]. It helps control blood sugar and leads to more weight loss than Saxenda^® [18].

‍

Why Semaglutide Is Better For Weight Loss

Clinical trials show semaglutide as the more effective option for weight loss than liraglutide (Saxenda^®) [18]. One study found that semaglutide led to a mean weight change of –15.8% compared to –6.4% with liraglutide [18]. Another trial reported that semaglutide caused more weight loss across different doses [18]. Keep in mind that semaglutide might cause more side effects than liraglutide [18].

‍

Many people have successfully lost weight using this drug in conjunction with lifestyle changes, such as diet and exercise. These semaglutide success stories show how semaglutide can help people lose weight and boost their overall health when paired with a healthy diet and exercise. Always talk to your doctor to figure out the best way to treat your condition. It's essential to understand semaglutide dosages and guidelines. Follow your healthcare provider's instructions carefully and report any side effects or concerns you may experience while using semaglutide.
