Saxenda® dosing information1

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

Your healthcare professional will start you on a low dose of 0.6 mg of the active ingredient, liraglutide. Each week this will increase by 0.6 mg until you reach the full Saxenda® dose of 3.0 mg. Keep using this dose until the treatment period ends. Do not increase your dose further. Your healthcare professional will assess your treatment on a regular basis.

Why does the dose of Saxenda® increase over the first month?1

The Saxenda® dosing schedule is designed to minimize any nausea you may experience. Nausea is a common side effect. As you progress to a higher dose, your body will adjust to the medication and the nausea will likely decrease.

As with all medications, Saxenda® may cause side effects, although not everyone will experience them. If you experience any side effects, you should speak to your healthcare professional.

How do I take Saxenda®?1

The active ingredient, liraglutide, comes in a pre-filled Saxenda® injection pen. Before you take Saxenda® for the first time, your healthcare professional will show you how to use the Saxenda® pen.

For further information on how to use your Saxenda® injection pen, visit the How to use your Saxenda® injection pen page of this website.

What time of day should I take my Saxenda® dose?1

You can take Saxenda® at any time of the day, regardless of when you eat meals. However, it is recommended that you take your Saxenda® dose at around the same time each day. Find the time that works best for you and make it part of your daily routine.

How long does a Saxenda® pen last?2

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

What happens if I miss a dose of Saxenda®?1

If you forget a dose but remember within 12 hours of when you usually take your Saxenda® dose, inject it straight away. However, if more than 12 hours have passed since you should have used Saxenda®, skip the missed dose and inject Saxenda® the following day at your usual time.

It is important not to inject a double dose or increase the dose on the following day to make up for the missed dose.

What happens if I overdose?2

If you use more Saxenda® than you should, talk to a healthcare professional or go to a hospital straight away. Take the medicine pack with you. You may need medical treatment. You may feel sick or actually vomit.

When should Saxenda® be discontinued?1

When you reach week 16 (or 12 weeks on the full Saxenda® dose), your healthcare professional will assess if the treatment 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 treatment.

Your healthcare professional will assess your treatment on a regular basis. Staying on Saxenda® can help you maintain your weight loss over the long term.

If you haven’t achieved at least 5% weight loss after 16 weeks, you and your healthcare professional should stop treatment and revisit your weight management plan or treatment options.

During the initial Saxenda® dosing schedule, if you cannot tolerate the next dose step for two consecutive weeks, you should consider discontinuing treatment. Do not stop using Saxenda® without talking to a healthcare professional.
