Saxenda is an effective weight loss treatment containing liraglutide. It mimics the hormone your body releases after eating a meal. It’s a subcutaneous injection pen you administer through the skin (not the kind you inject into a vein). You’ll inject it once a day, starting off on a low dose, which will gradually increase over the weeks.
Saxenda is suitable for individuals with a BMI of 30 or above, or 27 and have a weight related health condition where losing weight could help (such as diabetes, hypertension or sleep apnoea).
How does Saxenda work?
Saxenda works by helping you feel full. The active ingredient in Saxenda (liraglutide) mimics the GLP-1 hormone that’s released after a meal. It interacts with receptors in the brain, controlling hunger and making you feel fuller. This helps you to eat less, and in turn lose weight.
How well does Saxenda work?
Saxenda has been found to be an effective weight loss medication. In one study, patients using Saxenda lost 6.3% of their weight within four months, and 7.1% in six months. [1] A meta-analysis also found that patients using Saxenda alongside a low-calorie diet and physical activit-injections/y lost 5 to 10% of weight compared with placebo. [2]
As effective as Saxenda has shown to be, it’s important to remember that you’ll need to eat a calorie deficit diet and exercise regularly for it to work at its best.

How to use Saxenda
You can inject Saxenda at any time of the day, but try to do it at the same time each day. Choose a time that’s easy to remember (for example at breakfast-time). It can be taken with or without food.
Preparation:
Pull off the cap and check the solution in your pen is clear and colourless.
Take a new needle and attach it to the pen (always use a new needle for each injection).
Push the needle in straight and turn it so it’s on tight.
Remove the outer cap and keep it aside. Throw the inner cap away.
Check the flow:
You only need to check the flow of the first injection with each new pen. If this is not your first use, you can skip this step.
Turn the dose selector to the flow check symbol (the symbol will have two dots and a line).
With the pen held upright, press the button until the dose counter turns to zero.
A small drop should appear at the needle tip. If no drop appears, repeat step 2 up to six times until a drop appears. If no drop appears after six times, discard the pen and use a new one.
Using the pen:
Turn the dose selector to the correct dose.
Inject the needle into your waist, thigh or upper arm.
Press and hold down the button until the dose selector returns to zero. You might hear a clicking sound when it does.
Continue pressing down for six seconds, then remove the needle from your skin.
After injecting:
Lead the needle to the outer cap and push the cap on carefully. Make sure not to touch the needle.
With the cap on, unscrew the needle and dispose of it.
Put the pen cap back on.
For more detailed instructions, check the patient information leaflet.
What dose do I use?
You’ll start with the lowest dose, 0.6mg, which you’ll use for the first week. Each week, the dose will increase by 0.6mg like this:
Once you reach week 5, you’ll continue to use 3.0mg until the end of your treatment. This is known as the maintenance dose.
Your clinician will check in with you regularly when you’re using Saxenda to see how it’s working.
How long does one pen last?
It depends on which stage you’re at with your dosing. One pen contains 18mg of the medication in 3ml of solution. Your first pen will last you 17 days. The second pen will last you 8 days. After this, you’ll be on the maintenance dose of 3.0mg, so each pen will last you 6 days.
What if I take too much Saxenda?
If you take too much Saxenda, seek medical attention at your nearest emergency department. You might experience the following symptoms:
nausea,
vomiting, and
hypoglycemia (low blood sugar).
What to do about Saxenda missed doses
If you’ve missed a dose and it’s been less than 12 hours since your normal scheduled time, inject it as soon as possible. But if it’s been more than 12 hours, skip the missed dose and continue with your normal dosing schedule.
In any case, don’t take a double dose of Saxenda to make up for a missed dose

FAQ: Saxenda
Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.
How long does Saxenda take to work?
Answer:
You might start to see results as early as 4 weeks.[3] Generally, you’ll take Saxenda for an initial 12 weeks. If after 12 weeks you haven't lost at least 5% of your body weight, your clinician may recommend that you stop the treatment.
How does Saxenda compare with Wegovy?
Answer:
Saxenda and Wegovy are both in the category of GLP-1 receptor agonists. They work similarly but contain different ingredients. A big difference between the two is that Wegovy is taken weekly, whereas Saxenda is taken daily.
When the effectiveness was compared in a 68 week study, Wegovy was found to be more effective. Patients using semaglutide (Wegovy) lost 15.8% of their weight compared to only 6.4% with liraglutide (Saxenda). It was also more tolerable as only 13.5% discontinued using semaglutide, compared to 27.6% with liraglutide.[4]
Additionally, it’s cheaper to use Wegovy than Saxenda. On the maintenance dose, one Wegovy pen costs £200 and lasts for four weeks. Whereas, over a four week period with Saxenda on the maintenance dose, you would need approximately five Saxenda pens, which would total around £430 (each Saxenda pen costs £86).
Can you get side effects with Saxenda?
Answer:
You might experience some side effects when taking Saxenda. The most common side effects include:
nausea;
vomiting;
diarrhoea;
tiredness;
constipation, and
headache.
These side effects should go away within a couple of days as your body adjusts to it. If they persist, let your clinician know.
There are some ways you can manage the symptoms. For example, you can tackle nausea by drinking plenty of water, eating high protein meals and drinking ginger herbal tea.
Saxenda and alcohol
Answer:
There aren't any known contradictions between Saxenda and alcohol, but your clinician might recommend limiting your alcohol intake. Drinking alcohol might worsen some of your side effects. Additionally, too much alcohol can contribute significantly to your calorie intake, affecting your weight loss.
Is Saxenda the same as Ozempic?
Answer:
No, Saxenda is prescribed for weight loss, whereas Ozempic is a diabetes treatment. Although both contain active ingredients from the same drug class, they are different: Saxenda contains liraglutide and Ozempic contains semaglutide.
Is there a meal plan I should follow when taking Saxenda?
Answer:
You don’t need to follow a specific diet plan, but a low calorie diet alongside regular exercise will likely produce the best weight loss results.
It’s generally recommended to aim for a calorie deficit of 500 calories per day to lose one pound per week.[1] You should also try to exercise around 150 minutes each week.
Is there a generic version of Saxenda?
Answer:
Yes. As of 2026, a few generic versions of Saxenda have been launched: Biolide, Nevolat, and Plaobes. These contain the same active ingredient as Saxenda in the same dosage, so they work in exactly the same way. The only differences between the treatments should be the pen they come in, the branding, and sometimes the price.
Can I take Orlistat with Saxenda?
Answer:
Although there are no interactions between Orlistat and Saxenda, it’s not recommended to take them together.
The two weight loss medications work in different ways. Saxenda releases a hormone that makes you feel full more quickly. Whereas Orlistat stops the body absorbing fat by around 33%, so less fat is stored.
If you’re unsure about what treatment to choose, studies have shown that Saxenda is more effective than Orlistat[2] but it depends on a variety of factors, including your own personal needs and ability to tolerate each medication.
Can you get Saxenda without a prescription?
Answer:
Saxenda is a prescription-only medicine, so you can’t get it over the counter. This is so your clinician can check it's safe and suitable for you to use.

Users report that Saxenda is effective for weight loss, primarily by significantly reducing appetite, cravings, and promoting a feeling of fullness. Many find it easy to use and experience increased energy with few or no side effects. However, a notable number of users found the product ineffective. Some also mention that its effectiveness can decrease over time. Nausea, especially during the initial phase, is a commonly cited side effect. The high cost is a frequent concern.
