Saxenda (liraglutide 3.0mg) is a once-daily weight loss injection prescribed for chronic weight management in adults and adolescents aged 12 and older. As a GLP-1 receptor agonist made by Novo Nordisk, Saxenda works by mimicking a natural hormone your body releases after eating, helping regulate appetite and reducing the urge to overeat. In clinical trials, adults using Saxenda alongside a reduced-calorie diet lost an average of 5% to 10% of their body weight over 12 months. Buy Saxenda (Liraglutide) Online for Weight Loss
Saxenda was the first GLP-1 medication approved by the FDA for chronic weight management and remains one of the few weight loss injections approved for adolescents.

What is Saxenda?
Saxenda is the brand name for liraglutide at a 3.0mg dose, delivered through a prefilled, reusable injection pen. It belongs to a class of medications called GLP-1 receptor agonists, which mimic glucagon-like peptide-1, a natural hormone that regulates appetite and digestion.
The same active ingredient at a lower dose is sold under the brand name Victoza for the treatment of type 2 diabetes. Saxenda is the higher-dose version specifically approved by the FDA for chronic weight management. Despite identical active ingredients, the two products are not interchangeable. Dosing schedules differ, and they are prescribed for different conditions.
Who manufactures Saxenda?
Saxenda is manufactured by Novo Nordisk, a Danish multinational pharmaceutical company founded in 1923. Novo Nordisk specializes in diabetes care, obesity, and rare endocrine diseases, and has produced insulin and related metabolic medications for over a century. The company also manufactures Wegovy and Ozempic, two newer GLP-1 medications. Saxenda was the first weight loss injection in this class approved by the FDA, receiving authorization in December 2014.
Why choose Saxenda over newer GLP-1 medications?
Newer medications such as Wegovy (semaglutide) and Mounjaro (tirzepatide) tend to produce greater average weight loss in clinical trials. Saxenda, despite producing more modest results, retains specific clinical advantages:
- Approved for adolescents aged 12 and older with obesity, alongside Wegovy.
- Daily dosing may suit patients who prefer a consistent daily routine over a once-weekly injection.
- Years of post-market safety data as the longest-marketed GLP-1 for weight management.
- Generally lower out-of-pocket cost than newer GLP-1 options, depending on supply availability.
- Useful as a starter or step-down option for patients who do not tolerate higher-dose newer GLP-1s.
Our licensed clinicians will help determine whether Saxenda or another GLP-1 medication is the better fit based on your medical history, age, and treatment goals.

How does Saxenda work?
[IMAGE 1: Saxenda mechanism of action diagram, original WebP base64 here]
Liraglutide is a synthetic version of the natural GLP-1 hormone, with a 97% structural similarity to the hormone your body produces after meals. Once injected, it works through three mechanisms that together reduce calorie intake:
- Appetite suppression. Liraglutide acts on appetite-regulating regions of the brain, particularly the hypothalamus. Patients typically experience reduced hunger between meals and feel satisfied with smaller portions.
- Slower gastric emptying. Food remains in the stomach longer than usual, extending the feeling of fullness after eating and reducing the urge to snack.
- Improved insulin response. Liraglutide stimulates the pancreas to release insulin more efficiently after meals, which helps prevent the blood sugar crashes that often trigger hunger and cravings.
The combined effect makes maintaining a calorie deficit, the foundation of sustainable weight loss, considerably easier than relying on willpower alone.
How quickly does Saxenda start working?
Most patients notice some appetite reduction within the first few days of treatment, though the most significant effects appear gradually as the dose is titrated upward. Visible weight loss typically becomes apparent after several weeks of treatment at higher dose tiers. Common early effects include:
- Reduced hunger between meals
- Smaller portion sizes feel satisfying
- Decreased interest in high-calorie or high-sugar foods
- A quieting of intrusive food-focused thoughts (sometimes called “food noise”)
The starter dose of 0.6mg is intended primarily to help your body adjust to the medication. Most patients only see meaningful weight loss results once they reach the 1.8mg or 3.0mg dose tier.
How effective is Saxenda for weight loss?
Clinical evidence comes primarily from the SCALE trial program, a series of phase 3 studies that evaluated liraglutide for weight management. Key findings:
- Average weight loss of 5% to 10% of starting body weight over 56 weeks at the 3.0mg dose, compared to roughly 2.6% on placebo.
- 63% of patients taking Saxenda lost at least 5% of their body weight, compared to 27% on placebo.
- 33% of patients achieved more than 10% body weight loss.
- For patients with type 2 diabetes, weight loss averaged 6.0% with simultaneous improvement in blood sugar control.
- Results in adolescents aged 12 to 17 with obesity were comparable to adult outcomes.
Individual results vary based on starting weight, dose tolerance, treatment duration, diet, physical activity, and underlying medical conditions. Patients who achieve at least a 5% loss after 12 weeks on the full 3.0mg dose generally see continued progress with ongoing treatment.

Saxenda dosing schedule
Saxenda is prescribed at a target maintenance dose of 3.0mg once daily. Treatment begins at a low dose and increases gradually each week to give the body time to adjust. This step-by-step process is called titration and reduces the gastrointestinal side effects most patients experience when starting GLP-1 therapy. Liraglutide Injection for Weight Management
| Week | Daily Dose | Purpose |
|---|---|---|
| 1 | 0.6mg once daily | Starter dose. Helps the body acclimate and reduces nausea and other early side effects. |
| 2 | 1.2mg once daily | First step-up. Most patients tolerate this dose well. |
| 3 | 1.8mg once daily | Continued escalation. Appetite suppression typically becomes more noticeable. |
| 4 | 2.4mg once daily | Approaching maintenance dose. |
| 5 onward | 3.0mg once daily | Full maintenance dose, taken long-term as part of the treatment plan. |
Your prescriber may slow the titration schedule if side effects are troublesome. If you cannot tolerate the next dose increase, your clinician may keep you at your current dose for an additional week before progressing.

How long does each Saxenda pen last?
Each Saxenda pen contains 18mg of liraglutide. The number of days a pen lasts depends on your current dose:
- 0.6mg dose: 30 days per pen
- 1.2mg dose: 15 days per pen
- 1.8mg dose: 10 days per pen
- 2.4mg dose: 7 days per pen
- 3.0mg dose: 6 days per pen
At the full 3.0mg maintenance dose, you will need approximately 5 pens per month. Most patients use 3 pens during the first month of treatment (covering the dose escalation phase) and 5 pens per month thereafter.
