Saxenda is a prescription medication used for chronic weight management in adults with a body mass index (BMI) of 30 or greater, or who have a BMI of 27 or greater and at least one weight-related condition [1]. It is also indicated for weight management in adolescents aged 12 years and older with a body weight above 60 kg and a BMI for age and sex that indicates obesity [1]. Saxenda is administered as a daily injection and is intended for use in conjunction with a reduced-calorie diet and increased physical activity [1].
How Does Saxenda Help with Weight Loss?
Saxenda contains the active ingredient liraglutide, which is a glucagon-like peptide-1 (GLP-1) receptor agonist [2]. Liraglutide mimics the action of the natural hormone GLP-1, which plays a role in regulating appetite [2]. It works by binding to GLP-1 receptors in the brain to increase feelings of fullness and decrease feelings of hunger, thereby helping to reduce calorie intake [2].
What are the Clinical Trial Results for Saxenda?
Clinical trials have shown that Saxenda, when used with a reduced-calorie diet and increased physical activity, resulted in statistically significant weight loss compared to placebo [1]. In one trial involving adults with overweight or obesity, approximately 63% of participants lost at least 5% of their body weight with Saxenda, while around 27% achieved this with placebo [1]. For those with type 2 diabetes, approximately 49% lost at least 5% of their body weight with Saxenda, compared to about 15% with placebo [1].
Who Should Not Use Saxenda?
Saxenda is not recommended for individuals with a personal or family history of medullary thyroid carcinoma (MTC) or for patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2) [1]. It is also not indicated for patients who have had a previous serious allergic reaction to liraglutide or any of the inactive ingredients in Saxenda [1].
What are the Potential Side Effects of Saxenda?
The most common side effects reported in clinical trials include nausea, diarrhea, constipation, vomiting, stomach pain, and headache [1]. These side effects are often dose-dependent and may decrease over time [1]. Serious allergic reactions, pancreatitis, gallbladder problems, kidney problems, and an increased heart rate have also been reported [1]. There is also a warning about the possibility of thyroid C-cell tumors in rats, and it is not known if Saxenda causes these tumors in humans [1].
How is Saxenda Administered?
Saxenda is injected subcutaneously once daily into the abdomen, thigh, or upper arm [1]. The dosage is gradually increased over the first five weeks of treatment to help improve gastrointestinal tolerability [1].
Can Saxenda Be Used with Other Weight Loss Medications?
Information regarding the combined use of Saxenda with other medications for weight loss is not detailed in the provided text, but it is generally prescribed as a standalone therapy in conjunction with lifestyle changes.
What is the Cost of Saxenda?
The cost of Saxenda can vary depending on insurance coverage, pharmacy, and dosage [3]. It is a prescription medication, and costs can be significant without insurance [3].
When Does Saxenda's Patent Expire?

What are the Alternatives to Saxenda for Weight Loss?

Lifestyle modifications, including diet and exercise, are also fundamental to weight management [1].
