Liraglutide (Saxenda)

Liraglutide is injected subcutaneously (under the skin) into the abdomen, upper thigh, or upper arm — rotating between these sites each day helps prevent skin irritation and lumps from building up. Keep a simple mental or written log of where you injected last. Always follow your prescriber's instructions on injection technique, and if you're unsure, ask your pharmacist for a demonstration.

Injecting liraglutide straight from the fridge can increase stinging and discomfort at the injection site. Take your pen out 10–15 minutes before your scheduled injection time to let it reach room temperature. Store unused pens in the fridge (2–8°C), and once opened, the current pen can be kept at room temperature (below 30°C) for up to 30 days.

Most people find the first week of daily injections the hardest psychologically. Using the same time each day (e.g. with breakfast, or before bed) anchors it to an existing habit. The pen is designed to be simple — once the technique is set, the injection itself takes under a minute.

Liraglutide is a once-daily injection and works best when taken at a consistent time each day — morning tends to suit most people as it becomes part of a morning routine. Linking your injection to an existing habit (like making your morning coffee or brushing your teeth) makes it much easier to remember. Always follow your prescriber's instructions if they've recommended a specific time for you.

When your appetite is suppressed, it's easy to under-eat — and when you do eat less, protein is the most important nutrient to prioritise to protect your muscle mass. Aim for a palm-sized portion of protein (chicken, fish, eggs, legumes, Greek yoghurt) at breakfast, lunch, and dinner. Even on days when you're not very hungry, a small high-protein meal is far better than skipping entirely.

All significant SCALE trial weight-loss data is at 3.0 mg daily. If you are held at 1.8 mg or 2.4 mg due to tolerability, it is worth an honest conversation with your prescriber about expected outcomes versus a weekly agent.

Large meals are one of the most common triggers for nausea on liraglutide — your stomach empties more slowly on this medication, so overshooting your new fullness threshold can feel very uncomfortable. Try eating 4–5 smaller meals or snacks spread throughout the day rather than three large ones. Stopping at the first sign of fullness, rather than finishing your plate, is a habit worth building early.

If you respond well to Saxenda but your prescriber later discusses switching to a weekly agent, this is a clinical upgrade, not a sign of failure. The GLP-1 medicine class has evolved significantly since liraglutide was first approved.

Drinking large volumes of water quickly can worsen bloating and nausea, especially around meal times. Instead, keep a 600 mL or 1 litre water bottle with you and sip steadily throughout the day, aiming for at least 2 litres total. Try not to drink large amounts of fluid during meals, as this can increase feelings of fullness and discomfort.

Ginger tea is one of the most well-supported natural remedies for nausea and is safe for most people to use alongside their medication. Keep herbal tea bags on hand — especially in the first four to six weeks — and sip on a warm cup when nausea strikes. Peppermint tea is another great option if ginger isn't to your taste.

Weight loss with liraglutide is typically gradual and won't follow a perfectly straight line — some weeks the scales won't move even when you're doing everything right. Make a habit of tracking non-scale victories: improved sleep, more energy, smaller portions feeling satisfying, or feeling more comfortable in movement. These changes are meaningful and reflect real progress, even when the scales disagree.

Weeks one through four can genuinely be tough — nausea, fatigue, and no visible results yet can make it hard to stay motivated. It's completely normal to wonder whether it's worth it during this phase. Most people find that side effects ease significantly after the adjustment period, and the benefits of the medication become much more apparent from around week five onwards. You're building the foundation right now.

In the early weeks when nausea and fatigue are common, gentle movement is far more sustainable than jumping straight into a demanding exercise routine. A 20–30 minute walk each day is an excellent starting point and pairs well with the medication's effects. As you feel better and your energy improves — typically from around week six — you can gradually build in strength training, which is particularly valuable for preserving muscle during weight loss.

If nausea is worse in the mornings after your injection, scheduling your walk or workout for the afternoon or evening when you're feeling better makes exercise far more enjoyable and sustainable. Listen to your body — there's no single "right" time to exercise, and consistency matters far more than timing. Aim for at least 150 minutes of moderate movement per week as a long-term goal, in line with Australian physical activity guidelines.

Poor sleep increases hunger hormones (particularly ghrelin) and can partially counteract the appetite-regulating benefits of liraglutide. Aim for 7–9 hours of quality sleep per night by keeping a consistent bedtime, limiting screen use in the hour before bed, and keeping your bedroom cool and dark. If disrupted sleep is an ongoing issue, it's worth raising with your prescriber as part of your broader health picture.
