If you are considering Wegovy — or have just started treatment — one of the first questions most people ask is: “How do the doses actually work, and what do they mean in real life?”

This guide explains the Wegovy dosage schedule used in the UK, what each stage is clinically designed to do, how patients commonly feel at each dose, and the practical things you need to know — including what to do if you miss a dose, how to inject correctly, and when to talk to your prescriber during titration.

The Short Answer — Before You Read On

Wegovy uses a 16-week titration across five dose levels: 0.25mg → 0.5mg → 1mg → 1.7mg → 2.4mg maintenance
Each dose is held for 4 weeks before increasing, per the MHRA Summary of Product Characteristics
The starter dose (0.25mg) is for tolerance, not weight loss — appetite changes typically become clear from 1mg onward
At the 2.4mg maintenance dose, average weight loss in the STEP-1 trial reached ~15% over 68 weeks
Not everyone needs to reach the maximum dose — some maintain at 1mg or 1.7mg if appetite control is sufficient
Dose progression can be slowed, held, or in some cases reduced — it is always personalised, not automated
If you miss a dose, take it within 5 days; if longer, skip it and resume your regular weekly schedule

Why Wegovy Uses a Dose-Escalation Schedule

Wegovy (semaglutide) is not started at a high dose. Instead, treatment follows a gradual increase — and there is a clear clinical reason for this.

Wegovy works by activating GLP-1 receptors, which affect appetite, gastric emptying, and digestion. When the body first encounters these effects, they can produce noticeable side effects — primarily nausea and gastrointestinal symptoms. A gradual dose increase allows the body to adapt to each step before the next.

The main goals of dose escalation are to:

Allow the body to adapt gradually to GLP-1 receptor activation
Reduce the intensity of nausea and other gastrointestinal effects
Improve long-term tolerance, which makes patients more likely to stay on treatment
Identify the right dose for each individual — some respond well at lower doses

This approach prioritises tolerance, safety, and sustainability, not speed. Patients who progress too quickly are more likely to experience severe side effects and abandon treatment — which is the opposite of what either patient or prescriber wants.

The Full 16-Week Titration Schedule

Wegovy is taken as a once-weekly subcutaneous injection. The MHRA-approved schedule progresses through five dose levels, with each dose held for 4 weeks before increasing.

Dose	Weeks	Purpose	What to Expect
0.25mg	Weeks 1-4	Starter dose — tolerance building	Little or no weight loss; body adjusting
0.5mg	Weeks 5-8	Comfort-building dose	Subtle appetite changes; food urgency reduces
1mg	Weeks 9-12	Early weight loss support	Clearer appetite control; first visible weight changes
1.7mg	Weeks 13-16	Intermediate appetite control	Stronger satiety; predictable eating patterns
2.4mg	Week 17+	Maintenance dose	Maximum efficacy; ~15% weight loss in STEP-1 over 68 weeks

Not everyone progresses at the same pace, and not everyone needs to reach the maximum dose. Around 70% of patients in the STEP-1 trial reached the 2.4mg dose; others remained at lower doses with continued benefit.

Understanding costs at each stage

Medication costs vary by dose level. Wegovy at Slinic ranges from £99.99/month (0.25mg starter) to £209.99/month (2.4mg maintenance). For a full breakdown: Wegovy cost UK 2026: private prescription prices explained.

What Each Dose Feels Like in Everyday Terms

Clinical descriptions don’t always capture what patients actually experience. This section describes what most people notice at each stage of treatment — though individual response varies.

0.25mg — The Starter Dose

Weeks 1-4

This is the first dose for nearly everyone starting Wegovy. It is not designed to cause weight loss — its purpose is to introduce GLP-1 effects gently and help your body adjust.

Most patients notice:

Little or no change in appetite
Mild digestive sensations — a fuller feeling, slight nausea, or unusual bowel patterns
No visible weight change (which is normal and expected)
Side effects, if they appear, are usually mild and settle within a few days of each injection

If you don’t feel anything different, that is completely normal at this dose. Don’t be tempted to increase it on your own — the 0.25mg phase has a clinical purpose.

0.5mg — Building Comfort

Weeks 5-8

By this stage, appetite changes typically become more noticeable. Many patients describe:

Food feeling less “urgent” — the constant background drive to eat softens
Reduced between-meal snacking
Earlier feelings of fullness during meals
Better tolerance compared to the first weeks (the body has now adapted)

If nausea appeared earlier, it often settles around this point. Weight loss may begin to show but is usually still modest at this stage.

1mg — Early Weight Loss Support

Weeks 9-12

This is often the first dose where consistent appetite control becomes clearer. Patients commonly notice:

Naturally smaller portion sizes
Reduced cravings, particularly for high-fat or high-sugar foods
The first clear, visible weight changes — typically 3-5kg by this point
More predictable eating patterns through the week

This is where many patients begin to feel the treatment “working” in a noticeable way.

1.7mg — Deeper Appetite Support

Weeks 13-16

At this dose, appetite suppression may feel stronger and more consistent. Many patients report:

Meals feeling satisfying significantly sooner than before treatment
Eating patterns becoming much more predictable
Continued weight loss — often around 7-10kg total by this point
A shift in food preferences toward simpler, lighter foods

This dose helps bridge early progress with longer-term treatment goals.

2.4mg — The Maintenance Dose

Week 17+

This is the highest standard dose of Wegovy. Most patients remain on this dose for ongoing treatment, though it is not mandatory for everyone.

At the 2.4mg maintenance dose, patients typically experience:

Steady, sustained appetite control week to week
Maximum therapeutic effect — average weight loss of ~15% over 68 weeks in the STEP-1 trial
Predictable eating patterns that feel more like “the new normal”
Continued gradual weight loss for many months, often plateauing around 12-15 months

Treatment remains personalised at this point. Some patients achieve excellent results at lower doses and can be maintained there. For realistic timelines: how fast you can lose weight on Wegovy.

How Long You Stay on Each Dose

The standard MHRA schedule specifies 4 weeks at each dose during titration, but this isn’t always how it plays out in practice. A prescriber may recommend:

Standard 4-week intervals if tolerance is good and progress is steady
Extended time at a particular dose if side effects are still settling — 6 or even 8 weeks before increasing
Slowing progression entirely for patients who are particularly sensitive to GLP-1 effects
Holding at a lower dose if appetite control is already sufficient and weight loss is on track — not everyone needs the maximum dose

Dose progression is adjusted based on how you feel and how your body is responding — not just a fixed schedule. This is one of the most important reasons that proper pharmacist-led care matters for these medications.

What to Do If You Miss a Dose

Missed doses happen — most patients miss at least one over the course of treatment. The MHRA Summary of Product Characteristics gives clear guidance.

Wegovy missed-dose rule (5-day window)

If you remember within 5 days of the missed dose: take it as soon as possible, then continue your regular weekly schedule on your usual day.

If more than 5 days have passed: skip the missed dose entirely. Take your next scheduled dose on your usual day. Do not take two doses close together to “catch up”.

If you miss multiple consecutive doses (typically 2 or more), contact your prescriber. They may recommend either resuming at your current dose with caution, or returning to a lower dose temporarily before working back up — because tolerance can reduce after a gap.

Tip: pick a regular day for your weekly injection that fits your routine. Some patients find a weekend day works well so they can rest if any side effects appear after the injection.

How to Inject Wegovy Correctly

Wegovy is delivered via a pre-filled, single-use FlexTouch pen. The injection technique is straightforward once you’ve done it a few times.

Where to inject

Wegovy is a subcutaneous (under-the-skin) injection. Three approved injection sites:

Front of the thigh — easiest for most patients
Abdomen — at least 5cm away from the belly button
Upper arm — usually only practical if a family member or partner can help

Best practice

Rotate injection sites each week to reduce the chance of skin irritation
Clean the skin with an alcohol wipe and let it dry fully
Pinch the skin gently to lift it slightly
Hold the pen firmly against the skin at a 90-degree angle
Press and hold the dose button until the marking shows 0 — then count to 6 before removing the needle (this ensures full delivery)
Dispose of the pen safely in a sharps bin — never in household waste

The Wegovy pen comes with a patient information leaflet with full injection instructions, and your prescribing pharmacist can walk you through the technique on your first dose. Many patients find the first injection nerve-wracking and the second injection completely routine.

Why You Shouldn’t Skip Doses or Self-Adjust

Skipping doses, increasing too quickly, or self-adjusting based on social media advice all increase the risk of:

More intense nausea, vomiting, and digestive discomfort
Reduced tolerance — making it harder to continue treatment
Side effects severe enough to require stopping the medication entirely
Loss of the steady-state exposure that makes Wegovy work

Following the gradual progression under clinical guidance is what makes treatment manageable. If you’re struggling with side effects, the answer is not to skip the next dose — it’s to talk to your prescriber, who can slow the progression instead.

Always follow prescriber guidance

Never adjust your dose without discussing it first. If side effects occur, your prescriber can slow the pace, hold at a current dose, or in some cases reduce — rather than stopping or skipping. For practical strategies: Wegovy side effects guide.

When to Talk to Your Prescriber During Titration

You should contact your prescriber during the titration phase if:

Side effects are interfering with eating, hydration, or daily life
Nausea or vomiting persists beyond the first 2 weeks at a new dose
You’ve missed more than one consecutive dose
You’re due a dose increase but haven’t fully adjusted to your current dose
You’re not seeing any appetite changes by 1mg (around week 9-12)
Weight loss has stalled for more than 4-6 weeks at a maintenance dose
You experience any of the serious side effects listed in the side effects guide
You want to discuss whether you need to progress to the next dose at all

Early conversations prevent small issues becoming larger ones. Patients on Slinic’s service have direct access to pharmacist-led clinical support throughout treatment, not just at scheduled review points.

Why Pharmacist-Led Dose Management Matters

Wegovy titration is one of the clearest examples of why GLP-1 treatments benefit from specialist clinical oversight. A qualified prescriber tailors dosing based on your medical history, your response to each dose, the side effect profile you’re experiencing, and your weight loss goals.

Frequently Asked Questions

What are the Wegovy dosage levels?+

Wegovy uses five dose levels delivered weekly: 0.25mg, 0.5mg, 1mg, 1.7mg, and 2.4mg. The 16-week titration is designed to help the body adjust gradually and reduce side effects. 2.4mg is the maintenance dose for ongoing treatment.

Is 0.25mg of Wegovy a weight-loss dose?+

No. The 0.25mg dose is a starter dose designed to improve tolerance and help the body adapt to GLP-1 effects. It is not expected to cause meaningful weight loss. Appetite suppression typically becomes noticeable from around 1mg onward (weeks 9-12).

How long do you stay on each Wegovy dose?+

The standard MHRA-approved schedule is 4 weeks at each dose during titration, reaching the 2.4mg maintenance dose at around week 17. However, prescribers may extend a particular dose if you are still adjusting to side effects — 6 or even 8 weeks at a current dose is sometimes appropriate.

What does 2.4mg Wegovy feel like?+

Many patients experience steady, sustained appetite control and predictable eating patterns at the 2.4mg maintenance dose. In the STEP-1 trial, average weight loss reached ~15% over 68 weeks at this dose. Individual experience varies significantly — some patients describe it as “the new normal” rather than a dramatic change.

Do you have to reach the highest Wegovy dose?+

Not always. Some patients achieve good results at lower doses (1mg or 1.7mg) and can be maintained there if appetite control is sufficient and side effects are minimal. The 2.4mg dose generally produces the strongest weight loss outcomes, but individual response varies. Around 30% of patients in the STEP-1 trial did not reach the maximum dose.

Can Wegovy doses be adjusted?+

Yes. Dose progression is personalised. Your prescriber can hold you at a current dose for longer, slow the schedule, or in some cases return to a lower dose if side effects are severe. The goal is to find the right balance between appetite control and tolerability for you specifically.

What should I do if I miss a Wegovy dose?+

If you remember within 5 days of the missed dose, take it as soon as possible and continue your regular weekly schedule. If more than 5 days have passed, skip the missed dose entirely and take your next dose on your usual day. Do not take two doses close together to “catch up”. If you miss multiple consecutive doses, contact your prescriber — tolerance can reduce after a gap and your dose may need to be lowered temporarily.
