How often is Wegovy injected — and what happens between doses?

Picture your first injection day

You've received your pen, you've read the leaflet, and you're choosing which day of the week will become your Wegovy day. It's a decision worth taking a moment over. Pick a day you can reliably remember, many people anchor it to something routine, like the start of the working week or a weekend morning before the day fills up.

The first dose is 0.25mg. A lot of people expect this to feel like a treatment dose, and it doesn't, not immediately. That starter dose exists to let your body adjust to semaglutide's effects on the gut before the dose climbs. Nausea is the side effect most people are cautious about, and keeping the starting dose modest reduces how pronounced that is. Seven days later, you take the next pen at the same strength. Four weeks in at 0.25mg, your prescriber moves you to 0.5mg.

The injection itself is subcutaneous, just under the skin, not into muscle. The technique for giving a Wegovy injection is straightforward once you've done it the first time, and the pre-filled pen is designed to make it as simple as possible. Rotate the site each week to avoid localised irritation.

How the dose increases over the months that follow

The full escalation runs: 0.25mg for four weeks, 0.5mg for four weeks, 1.0mg for four weeks, 1.7mg for four weeks, then 2.4mg as the maintenance dose. That's a minimum of around 17 weeks before you reach the standard maintenance level, and the pace isn't negotiable, skipping rungs isn't how the medicine is designed to work, and your prescriber won't recommend it.

A common misconception worth clearing up: some people assume they should feel significant weight loss during the 0.25mg and 0.5mg weeks, and worry if they don't. Appetite suppression typically becomes more noticeable as the dose climbs. Patience in those early months pays off once maintenance is reached.

With the MHRA's approval of the higher 7.2mg dose, the escalation pathway can continue beyond 2.4mg for eligible patients, as described in the full Wegovy treatment overview. The same once-weekly frequency applies at every level. The NHS medicines page for semaglutide sets out the escalation schedule alongside what to do if a dose is missed.

What to do when life gets in the way of your injection day

The injection window is more forgiving than many people realise. If you miss your usual day, you have until two days (48 hours) after your normal injection time to take it, and our guide to how often the Wegovy injection is given explains exactly how that window works in practice. After that, skip the missed dose and wait for the next scheduled day, doubling up is not the right response. Your patient information leaflet spells this out clearly, and if you're uncertain, a message to your prescribing team is the sensible move.

Travel, illness, or simply forgetting are all common, and if you want a straightforward answer on how often you inject Wegovy and what flexibility you have around that, our dedicated page covers it clearly. Storing the pen correctly matters: Wegovy requires refrigeration between 2°C and 8°C; the SmPC on the electronic Medicines Compendium covers the exact details for any limited time outside the fridge.

If you're comparing how Wegovy's frequency sits against other options, a look at how Ozempic's weekly schedule differs in its licensed use may be helpful context. For a plain comparison of what treatment costs across providers, Wegovy pricing in the UK covers the landscape honestly.

Getting onto the right schedule with clinical support

The once-weekly frequency is only part of the picture. When each dose increase happens, at what strength you stay if side effects are a problem, and whether the schedule fits your health history, those decisions sit with a prescriber, not a leaflet. Disposal of used pens matters too; a sharps container keeps that side of things safe and legal.

At nume, a GPhC-registered Independent Prescriber reads every consultation personally before any treatment is dispatched. There's no algorithm deciding your dose trajectory. If you'd like to understand whether Wegovy fits your situation and what the schedule would look like for you, speak to our prescribers through a free consultation, reviewed the same day.
