A daily, self-administered injection, Saxenda® is used for weight loss in addition to diet and exercise in adults who have obesity (a BMI of 30 or greater) or are overweight (a BMI of 27-30) and also have weight-related medical conditions such as type 2 diabetes or high blood pressure.1

6 easy steps to administer your Saxenda® pen1

Step 1 - Check Pen

1. Check your medication

  • Check the name and coloured label of your pen to make sure that it contains Saxenda®
  • Pull off the pen cap
  • Look through the pen window to check that the solution is clear and colourless. If the solution looks cloudy, do not use the pen.

Step 2 - Attach Needle

2. Attach a new needle

  • Pull off the paper tab from a new needle
  • Screw the needle straight and tightly onto your Saxenda® pen
  • Pull off both needle caps – keep the outer needle cap for later.

Step 3 - Check Flow

3. Check the flow with each new pen

  • Check the flow before the first injection with each new Saxenda® pen or if the pen is dropped
  • Hold the pen with the needle pointing up
  • Turn the dose selector until the ‘flow check’ symbol lines up with the pointer
  • Tap the pen gently, so any air bubbles rise to the top
  • Press the dose button until 0 mg lines up with the pointer. A drop of Saxenda® should appear at the needle tip.

Step 4 - Select Dose

4. Select your dose

  • Turn the dose selector to select the dose you need (0.6 mg, 1.2 mg, 1.8 mg, 2.4 mg, or 3.0 mg)
  • If you select a wrong dose by mistake, turn the dose selector backwards or forwards to select the right dose.

Step 5 - Inject Dose

5. Inject your dose

  • Press your Saxenda® pen onto your skin
  • Press the dose button until 0 mg lines up with the pointer
  • Keep the dose button pressed down and leave the needle under the skin for at least 6 seconds. This is to ensure that the full dose has been injected.

Step 6 - Remove Needle

6. Remove needle after your injection

  • Guide the needle into the outer needle cap
  • When the needle is covered, carefully push the outer needle cap completely on
  • Unscrew the needle and dispose of it carefully
  • Put the pen cap back on.

Practical tips for administering Saxenda®1

Use Saxenda® at any time of the day:

  • Saxenda® is taken once daily at any time, regardless of when you eat meals.
  • It is recommended that you take Saxenda® at the same time every day.

  • Do not inject into a vein or muscle.
  • Ask your healthcare professional which sites are recommended for you.

Main injection sites are the front of your thighs, the front of your stomach (abdomen), or your upper arms.

Always use a new needle for each injection:

  • Always remove the needle from your pen after each injection.
  • This may prevent blocked needles, contamination, infection, leakage of solution and inaccurate dosing.

Never share your Saxenda® pen or your needles with other people:

  • Always dispose of the needle after each injection.
  • Keep your pen and needles out of sight and reach of others, especially children.

Your Saxenda® dosing schedule1

In your first five weeks of treatment with Saxenda®, you will increase your daily dose each week.

Read more about dosing on the dosing page.

Your healthcare professional will start you on a low dose of 0.6 mg. Each week this will increase by 0.6 mg until you reach the full dose of 3.0 mg. From then on, you will stay on this dose.

Nausea is a common side effect and this dosing schedule is designed to minimise any nausea you may experience when you first begin treatment. As you progress to a higher dose, your body will adjust to the medication and any nausea will likely decrease.

For more information on potential side effects with Saxenda®, read the Patient Information Leaflet.

Some common questions answered

How do I store my Saxenda® pens correctly?1

  • Before opening, store Saxenda® pens in a refrigerator (2°C to 8°C). Do not freeze.
  • After first use, store at room temperature (below 30°C) or in a refrigerator (2°C to 8°C).
  • Pens in use should be thrown away after 30 days even if they still have Saxenda® left in them.
  • When not using the pen, keep the pen cap on in order to protect it from light.
  • Do not throw away any medicines via wastewater or household waste.
  • Ask your pharmacist how to throw away medicine you no longer use.

How long does a Saxenda® pen last?

  • Each Saxenda® pen contains 18 mg of liraglutide in 3 ml of solution.
  • At the maintenance dose of 3.0 mg per day, each pen will last six days.
  • Five prefilled Saxenda® pens provide 30 days’ supply at the maintenance dose.

How long can you continue taking Saxenda®?1

  • When you reach week 16 (or 12 weeks on the full dose), your healthcare professional will assess if Saxenda® is working for you.
  • At that point, if you have achieved a weight loss of 5% or more, it’s a good indicator that your body is responding well to treatment and you should continue Saxenda®.
  • If you haven’t achieved at least 5% weight loss, you and your healthcare professional should stop Saxenda® and revisit your weight management plan or treatment options.
