Wegovy Dosage: A Complete Guide

If you've just been prescribed Wegovy or you're weighing it up, understanding the Wegovy dosage schedule is one of the most reassuring things you can do before you start. Wegovy isn't a fixed, single dose  it's increased slowly, step by step, over several months, and knowing what's coming makes the whole process feel far more manageable. This guide walks you through the full schedule, what to expect at each stage, how side effects are handled, and what to do if you miss a dose. It's written to be genuinely helpful, but it's for information only and never replaces the instructions your own prescriber gives you.

Why Wegovy dosage starts low and builds up slowly

The single most important thing to understand about Wegovy dosage is that you don't start on your full dose. Treatment begins at the lowest strength and steps up gradually  an approach clinicians call "start low, go slow." The escalation runs over five steps, beginning at 0.25 mg once weekly for four weeks, then increasing every four weeks up to the maintenance dose.

The reason is tolerability, not caution for its own sake. Wegovy (semaglutide) works partly by slowing how quickly your stomach empties, which is what helps you feel full sooner  and that same action is what can cause the most common early side effects, like nausea. The starting 0.25 mg dose isn't really there to produce weight loss; its job is to let your digestive system adapt. Building up slowly gives your body time to adjust at each level, which keeps side effects to a minimum and makes it far more likely you'll stay comfortable on treatment. If you want to understand how this fits into the wider family of these treatments, our guide to GLP-1 weight-loss injections explains the mechanism in plain language.

The complete Wegovy dosage schedule

Wegovy follows a five-step ladder, with at least four weeks spent at each step before moving up. Here's the full Wegovy dosage schedule:

Because each step lasts four weeks, the earliest you'd normally reach the full 2.4 mg maintenance dose is around week 17. That timeline isn't a race  four weeks is the minimum time at each step, not a deadline, and your prescriber may keep you on a dose for longer if that's what suits you. The dose is always given as a once-weekly injection, and it can be taken at any time of day, with or without food  though it helps to pick the same day each week so it becomes a habit.

What to expect at each stage

In the first weeks on the lower doses, many people notice their appetite starting to change  smaller portions feel satisfying, and the constant pull toward snacking eases  often before the scales move much. Modest weight change, or even none, during the early window is completely expected and isn't a sign the treatment is failing.

Weight loss typically becomes more clearly noticeable from around the 1.0 mg step onward, and continues to build as you move up. The higher steps are where most of the effect accumulates, which is why reaching and holding a steady dose matters more than rushing to the top. It's worth setting expectations gently here: this is a gradual treatment measured over months, and steady, sustainable change is exactly what it's designed to produce. If you're curious how Wegovy compares with the other main option, our Mounjaro vs Wegovy guide breaks down the differences.

Managing side effects and adjusting the pace

The most common side effects are digestive  nausea, diarrhoea, constipation and sometimes vomiting. These tend to peak during the escalation phase and are mild to moderate for the large majority of people. They're usually worst in the days just after a dose increase and settle as your body adjusts, which is the whole reason the schedule steps up slowly.

If a dose increase brings on side effects you're struggling with, that's not a failure and it doesn't mean stopping. The recommended approach is to delay the next increase by four weeks rather than discontinue, or to step back down to the previous dose for a while before trying again. There's genuine flexibility built in. Practical things that help many people: eat smaller, lower-fat meals, stop eating when you feel full, stay well hydrated, and avoid very rich or greasy food on the days around an increase. Anything severe or persistent  ongoing vomiting, signs of dehydration, or severe abdominal pain  should always be reported to your prescriber promptly. It's also worth checking our guide on which medicines to be careful with alongside Wegovy, as interactions matter.

What to do if you miss a dose

Life happens, and an occasional missed weekly injection is manageable. The general rule:

If you remember within 5 days of the missed dose, take it as soon as possible and continue on your usual weekly day. If more than 5 days have passed, skip that dose and take your next one as scheduled. Never take two doses to make up for a missed one. If you've missed several weeks, speak to your prescriber before resuming they may want you to restart at a lower dose.

Reaching and staying on the maintenance dose

The target maintenance Wegovy dosage is 2.4 mg once weekly. That said, the top dose isn't the goal for everyone. Some people achieve strong results at a lower dose  0.5 mg, 1.0 mg or 1.7 mg  and can stay there long term, and 1.7 mg is a recognised maintenance option for those who can't comfortably tolerate 2.4 mg. The right maintenance dose is the one that gives you benefit without side effects you can't live with, decided with your clinician.

Consistency is what makes the difference over time, and this is also why the dose shouldn't be stopped or changed on your own  if you're thinking about pausing or coming off, it's worth reading what happens when you stop weight-loss medication first and discussing it with your prescriber, since appetite tends to return once treatment ends.

Why your Wegovy dosage should be set by a clinician

The schedule above is the standard framework, but your actual Wegovy dosage is set and adjusted by a prescriber who knows your history. Dosing is individualised around how you tolerate each step, other medicines you take, existing conditions and your goals  which is exactly why Wegovy is prescription-only rather than something to self-manage from a chart. Regular reviews are what keep it both effective and safe, and they're the right place to raise anything that isn't going smoothly. If you'd like to understand whether it's suitable for you, Medetone's weight-loss consultation is the starting point, and you can read more about the treatment itself on the Wegovy product page.

Frequently asked questions

What is the starting Wegovy dosage?

 Everyone starts at 0.25 mg once weekly for the first four weeks. This starter dose is about helping your body adjust, not about weight loss itself.

How long until I reach the full dose?

Following the standard four-week steps, the full 2.4 mg maintenance dose is usually reached at around week 17. It can take longer if you need more time at any step, and that's completely fine.

Can I speed up my Wegovy dosage?

No  the four-week minimum at each step exists to protect you from stronger side effects. Any change to the pace should be discussed with your prescriber.

Do I have to reach 2.4 mg?

Not necessarily. Some people do well on a lower maintenance dose and stay there. The best dose is the one that works for you with tolerable side effects.

What if side effects are difficult?

Tell your prescriber. The usual response is to hold or step back a dose rather than stop, giving your body more time to adjust.

In summary

Wegovy dosage follows a gradual, five-step path from 0.25 mg to a 2.4 mg maintenance dose, with at least four weeks at each level and plenty of flexibility to slow down if you need it. The schedule exists for your comfort and safety, and the specific dose is always a decision made with your clinician. Understanding what's ahead is one of the best ways to start treatment feeling prepared rather than anxious.
