Liraglutide for weight management

Liraglutide is a medication that belongs to a class of drugs called glucagon-like peptide-1 receptor agonists (GLP-1 receptor agonists). It is commonly prescribed under the brand name Saxenda for weight management in adults.

How liraglutide works

Liraglutide works by mimicking the action of a hormone called glucagon-like peptide-1 (GLP-1), which is normally released in the intestine after a meal. GLP-1 helps regulate blood sugar levels by stimulating the release of insulin and reducing the production of glucagon, a hormone that raises blood sugar. Additionally, liraglutide slows down gastric emptying, promotes a feeling of fullness, and reduces appetite, which can contribute to weight loss.

How long does it take to see results?

The timeline for seeing results with liraglutide can vary. In terms of blood sugar control, some people may experience improvements within a few days or weeks, but it can take up to three months to reach the full effect. Regarding weight loss, gradual and steady progress is typically observed over several months of treatment.

What side effects are possible?

As with any medication, liraglutide may cause side effects. Common side effects include nausea, vomiting, diarrhea, constipation, and decreased appetite. These side effects are often mild and tend to improve over time. However, if they persist or become severe, it is important to consult a healthcare professional. In rare cases, liraglutide may also lead to more serious side effects, such as pancreatitis, gallbladder problems, or thyroid tumors. These risks are generally low, but it is crucial to discuss them with your healthcare provider.

Is liraglutide right for me?

Liraglutide is prescribed as an injectable medication. The dose and administration instructions depend on the specific condition being treated. For type 2 diabetes, the usual starting dose is 0.6 mg once daily, which can be increased gradually to a maintenance dose of 1.2 mg or 1.8 mg once daily. For weight management, the recommended dose is 3 mg once daily. The injection is usually self-administered using a prefilled pen device, and it can be taken at any time of the day, with or without food. It is essential to follow the prescribed dosage and instructions provided by your healthcare professional.
