Saxenda (liraglutide) is a medication designed to aid in weight loss and the maintenance of weight loss after successful weight reduction. It is intended for use by obese adults, as well as overweight adults with weight-related medical conditions. Additionally, Saxenda can be prescribed to children aged 12 to 17 who are obese and have a bodyweight exceeding 132 pounds (60 kg). When combined with a healthy diet and regular exercise, Saxenda can provide an effective weight management solution.

Mechanism of Action: How Saxenda Works

Saxenda functions by reducing appetite, slowing down the emptying of the stomach, and promoting a sense of fullness, resulting in decreased calorie intake. The medication's active ingredient, liraglutide, is akin to a hormone naturally present in the body. This hormone helps regulate blood sugar levels, insulin production, and digestion. Saxenda falls under the category of glucagon-like peptide-1 (GLP-1) agonists, a class of drugs that work to control appetite and metabolism.

Approved Uses of Saxenda

Saxenda has been approved by the FDA for the following purposes:

**For Adults:**
1. Obese adults with a body mass index (BMI) of 30 kg/m² or higher.
2. Overweight adults with a BMI of 27 kg/m² or higher, who also have weight-related medical conditions such as hypertension, type 2 diabetes mellitus, or dyslipidemia.

**For Pediatric Patients Aged 12 and Older:**
1. Children with a body weight exceeding 60 kg.
2. Children whose initial BMI corresponds to 30 kg/m² or higher based on international cut-offs (Cole Criteria).

Administration and Dosage

Saxenda is administered as a subcutaneous injection once daily using a multi-dose injection pen. The dosage is gradually escalated over several weeks to minimize the likelihood of gastrointestinal symptoms:

**Adults:**
- Week 1: 0.6 mg subcutaneously once a day
- Week 2: 1.2 mg subcutaneously once a day
- Week 3: 1.8 mg subcutaneously once a day
- Week 4: 2.4 mg subcutaneously once a day
- Week 5: 3 mg subcutaneously once a day

**Pediatric Patients Aged 12 and Older:**
- Week 1: 0.6 mg subcutaneously once a day
- Week 2: 1.2 mg subcutaneously once a day
- Week 3: 1.8 mg subcutaneously once a day
- Week 4: 2.4 mg subcutaneously once a day
- Week 5: 3 mg subcutaneously once a day

After reaching the maintenance dose, the medication should be evaluated for effectiveness. If significant weight loss has not occurred, discontinuation may be recommended.

Precautions and Considerations

Before using Saxenda, it's crucial to discuss your medical history and current medications with your healthcare provider. Saxenda should not be used in combination with other GLP-1 receptor agonists. The medication is not recommended for individuals with certain conditions, such as multiple endocrine neoplasia type 2, a history of medullary thyroid carcinoma, insulin-dependent diabetes, diabetic ketoacidosis, or during pregnancy. It is important to note that Saxenda's safety and effectiveness in children under 12 and in adolescents aged 12 to 17 with type 2 diabetes have not been established.

Possible Side Effects

Common side effects of Saxenda may include nausea, vomiting, stomach pain, increased heart rate, diarrhea, constipation, headache, and dizziness. However, more severe reactions, such as changes in heart rate, mood, or behavior, suicidal thoughts, gallbladder problems, pancreatitis, or kidney issues, require immediate medical attention.

Conclusion

Saxenda, a medication designed to aid in weight loss and weight management, offers a potential solution for obese and overweight adults, as well as certain pediatric patients. By regulating appetite and promoting feelings of fullness, Saxenda contributes to a comprehensive approach to weight control when combined with a healthy diet and regular exercise. However, its usage must be carefully monitored and managed by a healthcare professional, considering potential side effects and individual medical circumstances. As with any medication, it is important to consult with your doctor before beginning Saxenda treatment.
