Titrating liraglutide: why treatment starts slowly
Liraglutide is injected daily and increased step by step. Why it works this way, how to handle the pen day to day, and what to do if you miss a dose.

In short
Liraglutide is a GLP-1 medicine injected under the skin once a day. You begin on the lowest dose and move up in fixed steps until you reach the maintenance dose.
How many steps there are and how far apart is set out in the product information and your prescription. This article explains the principle behind it. It does not replace the package leaflet or your doctor's decision about your dose.
Why not start on the full dose?
GLP-1 medicines slow down how quickly the stomach empties and change how fullness feels. That is exactly why the gut is sensitive at first: nausea, feeling full or changes in bowel habits are common in the early weeks.
Increasing step by step gives your body time to adjust. It is not excessive caution; it is a fixed part of the treatment.
How titration works in principle
You start at the lowest step and move up one step at a time at regular intervals until you reach the maintenance dose. The pen is designed so each step can be dialled in directly.
If a step isn't going well, for example because nausea is getting in the way of daily life, staying on that step for longer can make sense. Whether and for how long is decided by your prescribing doctor. Please don't go faster or higher on your own.
Important: the right dose is not automatically the highest. If you don't tolerate the maintenance dose well, agree the next steps with your prescriber. Going above the maximum dose in the product information is not intended. Whether and how a switch or a dose change happens is decided by the doctor in each individual case.
When to take stock
Many people notice early on that their appetite changes. Whether the treatment suits you, though, can only be judged sensibly after some time on the maintenance dose. The product information sets a fixed review point for this. If the result is too small, treatment is reassessed and stopped if appropriate.
That isn't meant to put pressure on you. It's a sensible guardrail: there's no point injecting a medicine for months if it is doing little for you.
The pen in everyday life
Liraglutide is injected into the fatty tissue under the skin, typically the abdomen, thigh or upper arm. Exact handling is in your pen's instructions for use. These points almost always apply:
- Wash your hands first and check briefly: right product, solution clear and colourless, within its expiry date
- Use a new needle for every injection. Needles are often not included and need to be bought separately.
- Dial the prescribed dose and keep the needle in for the hold time given in the instructions so the full dose is delivered
- Rotate injection sites regularly so the skin doesn't get irritated
- Unscrew the needle afterwards and dispose of it in a puncture-proof container; store the pen with its cap on
- Keep unopened pens in the fridge and never freeze them. How long a pen in use keeps without refrigeration is stated in the package leaflet.
Keep an eye on your supply
Because you inject every day and the dose rises at first, a pen runs out much faster on a higher dose than at the start. By the time you reach the maintenance dose at the latest, work out how long your supply will last and sort a new prescription in good time, especially before holidays. Whether and how a switch or a dose change happens is decided by the doctor in each individual case.
Missed a dose or injected twice?
The package leaflet gives a clear rule for a missed dose, depending on how much time has passed since your usual time. Look it up and follow it. One rule always applies: don't inject twice to catch up. It raises the risk of side effects without any benefit.
If you have accidentally injected too much, contact your pharmacy or a doctor. Severe vomiting or diarrhoea can drain a lot of fluid from the body, and then you need medical help promptly. Whether and how a switch or a dose change happens is decided by the doctor in each individual case.
Side effects: what's common and what helps
Most complaints appear during titration and affect the gut: nausea, feeling full, diarrhoea or constipation, sometimes heartburn or burping. What helps many people:
- Eat slowly and choose smaller portions. You'll feel full sooner than you're used to.
- Avoid very fatty and large meals at the start
- Drink enough across the day, especially with diarrhoea
- With strong nausea: light food and rest. Whether the next increase should wait is a question for your doctor.
- Get medical advice if complaints don't ease, if you can barely eat or drink, or if new, unusual symptoms appear
- Seek medical help immediately for severe, persistent abdominal pain that may spread to the back, or persistent vomiting
