Quick answer: 4mg is the second stage of the Wegovy pill schedule, usually starting on day 31 after four weeks at 1.5mg. It is where many people first notice a clearer effect on appetite. The dose typically continues for 30 days before your prescriber reviews whether to move you to 9mg.
UK availability: Available now, from 6 July 2026. Wegovy pill is private prescription only, and suitability is decided by the prescriber.
What is changing at this stage?
Moving from 1.5mg to 4mg is a meaningful step up, not a small adjustment, so it is common for tolerability effects to reappear briefly even if they settled at the starting dose.
This is a normal part of titration and usually eases within one to two weeks, similar to the pattern at 1.5mg. By this stage, many people describe a more noticeable reduction in appetite and portion sizes than they felt at the starting dose.
As with every stage, the tablet must still be taken on an empty stomach with a small amount of water, followed by at least 30 minutes before food, drink, or other oral medicines.
Commonly reported at this stage
- A return of mild nausea or stomach upset for the first one to two weeks after stepping up
- A clearer reduction in appetite or earlier feeling of fullness than at 1.5mg
- Occasional tiredness or mild headache during the adjustment window
- Some people continue with minimal side effects at this stage too
When to contact your prescriber
This is general guidance, not medical advice. If nausea or stomach upset is more severe than it was at 1.5mg, does not improve after a couple of weeks, or you experience vomiting that prevents keeping fluids down, contact your prescriber.
They may suggest staying at 4mg for longer before increasing further. Never increase your own dose ahead of schedule.

Frequently asked questions
Is nausea normal when starting the 4mg Wegovy tablet?
Yes. Nausea is most common during dose escalation, and moving from 1.5mg to 4mg more than doubles the semaglutide dose. Most people find nausea peaks in the first week and improves significantly by week two of the 4mg stage.
Will I lose more weight on 4mg than 1.5mg?
Yes, typically. Appetite suppression becomes more noticeable at 4mg, often leading to reduced calorie intake and early weight loss. However, the largest weight loss in clinical trials occurred at the 9mg and 25mg maintenance stages.
What can I eat to reduce nausea on the 4mg Wegovy tablet?
Smaller, slower meals help. Avoid fatty, fried, or spicy foods in the first two weeks at 4mg. Eating a little rather than skipping meals entirely is usually better, as an empty stomach can worsen nausea on semaglutide.
How long do I take the 4mg Wegovy tablet?
Four weeks (days 31 to 60). On day 61 you switch to 9mg. If you are struggling with side effects, your prescriber may advise staying at 4mg for a longer period before escalating.
