Saxenda Weight Loss Injections Pen

Saxenda is an MHRA and FDA approved weight loss medicine that is often prescribed when other weight loss efforts have been ineffective.

Since being approved for weight loss in 2014, Saxenda has helped many people achieve their weight loss goals.

Each pen comes pre-filled with 6mg/ml liraglutide - the same active ingredient found in other weight loss injection pens.

With Prescription Doctor, you can order Saxenda online from our UK pharmacy following an online consultation with one of our doctors.

Our pharmacy includes free needles and a sharps bin with every order, as well as a stylish carrying pouch when you order more than 3 pens. If you require more needles, you can order more needles here.

If your order is approved by one of our online doctors before 3 pm on weekdays, our UK based pharmacy will package your Saxenda order in discreet packaging and dispatch it to your door via fast next-day delivery.

Is Saxenda suitable for me?

Saxenda is licensed for weight loss in adults with a BMI greater than 30 kg/m² (obese), or people with a BMI of less than 30 kg/m² with weight-related health problems, such as:

  • diabetes
  • high blood pressure
  • high cholesterol
  • obstructive sleep apnoea

Saxenda may be prescribed "off-label" to those with a BMI under 30 kg/m².

Your doctor will provide a diet and exercise plan that you must follow while taking Saxenda.

Weight loss is a journey that takes hard work and dedication, with or without the help of medication. Once you finish treatment with Saxenda, you should continue to eat healthily and get regular exercise to maintain your new weight.

When you order Saxenda online from Prescription Doctor, our online prescriber will review your suitability. You can use the "my chats" portion of the website to ask our online prescriber any questions you have about Saxenda.

How long does a Saxenda pen last?

1 Saxenda pen will last for the first 17 days of treatment (starting from week 1).

You will need 3 Saxenda pens as you gradually increase your dose through the first 4 weeks of treatments.

From week 5, once you take the 3 mg dosage, 1x Saxenda pen will last you 6 days.

1 month of treatment with Saxenda at the maintenance dose (3.0 mg) will require 5 Saxenda pens.

How long a Saxenda pen lasts depends on what dosage you are on. Higher doses mean using more Saxenda, resulting in the pen lasting a shorter time.

How many Saxenda pens will I need to start treatment?

The typical starting dose is 0.6 mg. Your doctor will gradually increase your dosage of Saxenda by 0.6 mg each week until you reach the recommended dose of 3.0 mg once a day.

Please understand that the following is a guideline. Your doctor will need to monitor you while taking Saxenda. If they feel that increasing the dose is unsuitable - which may happen if a higher dose of liraglutide is not well tolerated - they will not increase the dosage further until they believe it is safe to do so.

Week No. Dosage (daily) No. of pens No. of needles
1 0.6 mg 1 ~20
2 1.2 mg
3 1.8 mg 2 ~30
4 2.4 mg 3 ~40
5 onward 3.0 mg 4 ~50


As the table shows above, you will need 4 Saxenda pens to reach the optimum dosage of 3 mg per day. Once you reach the optimum dosage, a single Saxenda Pen will last 6 days.

How much does 1 month of Saxenda treatment cost?

1 Month of treatment requires 5 Saxenda pen. We offer the option to buy 5 pens for £59.79 per pen. An adequate number of needles and a sharps bin will be included with your order.

Our prices start from as little £55.99 per pen when you order 10 pens.

How does Saxenda work?

The active ingredient of Saxenda — liraglutide — mimics a hormone in the body (GLP-1) that is released from the intestines following a meal.

Liraglutide increases the production of insulin, which reduces the amount of glucose in the blood. It also reduces the production of glucagon, which the liver uses to produce glucose.

In the digestive tract, GLP-1 slows down the absorption rate of glucose from the intestines to the blood.

Liraglutide also suppresses your appetite. This makes you feel less hungry, resulting in you consuming fewer calories.

Moreover, liraglutide has been shown to reverse pre-diabetes and significantly reduce the severity of obstructive sleep apnoea.

Saxenda does not speed up the way your body burns calories, or give you more energy to exercise.

While using Saxenda, it is important to eat a varied and balanced diet and exercise regularly. Saxenda alone is not enough to help you lose weight.

How effective is Saxenda for weight loss?

In clinical studies, more than 50% of people taking Saxenda lost 5% or more of their body weight after 12 weeks. This means someone weighing 77kgs could potentially lose 5kgs after 12 weeks.

After approximately 1 year (56 weeks) of taking Saxenda, 95% of people lost on average 8% of their body weight.

Over 3 years on Saxenda, 33% of responders continued to lose 10% or more of their baseline body weight.

You can read more about the Saxenda study carried out by the University of Leicester in collaboration with Novo Nordisk.

How much weight you can lose on Saxenda depends on many factors. It's best to discuss your weight loss goals with your doctor. They can provide you with a suitable weight loss plan tailored to your diet and lifestyle habits.

Managing side effects

The common side effects of Saxenda are nausea, vomiting, constipation and diarrhoea. While they usually reduce over time, there are some things you can do to reduce your risk of side effects.

Firstly, it is important to administer Saxenda at the same time every day. If you find it difficult to remember when to take Saxenda, set a reminder on your phone or smart device.

Side effects such as diarrhoea and vomiting can dehydrate you. It would be best if you stay hydrated while taking Saxenda by drinking plenty of water throughout the day.

You may find that your side effects become more prominent when you increase your dosage. If you cannot tolerate the side effects, discuss your options with your doctor. Your dosage may need to be reduced. You should always follow the recommended dose escalation as prescribed by your doctor.

  • Wheezing or difficulty breathing

If you experience an allergic reaction after using Saxenda, inform your doctor straight away.

In cases of severe allergic reaction, stop using Saxenda and go straight to your nearest accident and emergency department. Remember to take the pen with you so that doctors treating you know exactly what and how much you took.
