Saxenda

What is Saxenda?

Saxenda is a prescription medication used for weight loss. When injected daily, Saxenda injections reduce appetite and delay stomach emptying, helping thousands worldwide to eat less and reach their weight loss goals.

Unlike other weight loss medications like Mounjaro and Ozempic, Saxenda is not approved to treat type 2 diabetes. Saxenda weight loss pens have been specially made to combat obesity.

How does Saxenda work?

Saxenda works by mimicking a naturally occurring hormone: glucagon-like peptide 1 (GLP-1). It belongs to a class of drugs known as GLP-1 receptor agonists.

GLP-1 receptor agonists like Saxenda act on receptors in the brain to reduce your appetite and cravings, making you eat less food. By doing this, Saxenda makes it easier to stay within a calorie deficit, which is essential for weight loss. When combined with a healthy diet and regular exercise, this helps you to lose weight effectively over time.

How much weight can I lose?

Saxenda is clinically proven to help you lose up to 10% or more of your total weight within 12 months. One clinical trial involving 3,371 patients using Saxenda for weight loss found that:

  • 63% of patients lost at least 5% body weight
  • 33% of patients lost more than 10% body weight
  • 14% of patients lost more than 15% body weight

Who can use Saxenda?

To be prescribed Saxenda from 121doc, you must be over the age of 18 and have:

  • A BMI over 30 or
  • a BMI over 27 with a weight-related health problem (such as diabetes or high blood pressure)

There are some people who cannot use Saxenda injection pens even if they meet one of the criteria above. You may not be able to use it if you:

  • believe you may be allergic to liraglutide
  • have severe heart failure
  • are over 75 years old
  • have kidney or liver disease
  • Have a stomach or gut problem like inflammatory bowel disease

How long does a Saxenda pen last?

Your first Saxenda weight loss pen should last for around 17 days, accounting for the dose increases every week. After you reach the maintenance dose of 3.0 mg, each pen should last you 6 days.

Keep in mind that some people may be instructed by their doctor to stay at a lower dose for medical reasons, and this will extend how long a pen lasts. Your doctor will prescribe your Saxenda dose schedule in your consultation.

How long does Saxenda take to work?

Saxenda should start working within 1 to 2 days, and you should first begin to see results within a few weeks.

Are there any foods to avoid while on Saxenda?

There are no restricted foods when taking Saxenda, so you shouldn’t need to avoid anything entirely, so long as you’re staying within a calorie deficit. However, some foods can make this more difficult, and should only be had in moderation.

In general some foods and drinks to limit include:

  • Sugary snacks
  • Fried and high-fat foods
  • Fizzy drinks and sugary fruit juices
  • Alcoholic drinks
  • Highly processed snacks (like crisps)
