Wegovy UK: Doses, Dosage Schedule and How to Use the Pen

Wegovy in the UK is a prescription semaglutide injection used once weekly for weight management in eligible adults alongside a reduced-calorie diet and increased physical activity. For adults in the UK who are considering Wegovy or already have a prescription and need clear guidance on dosing, administration and clinical review points, the key thing to know is that treatment does not usually begin at the eventual maintenance dose.

The standard starting dose is:

0.25 mg once weekly.

The dose is then increased gradually at four-week intervals:

0.25 mg

↓

0.5 mg

↓

1 mg

↓

1.7 mg

↓

2.4 mg.

The gradual step-up is deliberate. It is intended to reduce the likelihood of gastrointestinal adverse effects while the body becomes accustomed to semaglutide. Current MHRA information confirms that Wegovy begins at 0.25 mg once weekly and is gradually increased every four weeks to 2.4 mg.

The UK dosing landscape changed significantly in 2026.

On 6 January 2026, the MHRA authorised a maximum semaglutide dose of 7.2 mg once weekly for weight management in adults living with obesity.

Then, on 14 April 2026, the MHRA approved a single-dose 7.2 mg Wegovy pen, allowing the maximum weekly dose to be given as one injection rather than the earlier three consecutive 2.4 mg injections.

The 7.2 mg option does not mean everyone using Wegovy should increase to that dose.

For weight management, 2.4 mg remains an established maintenance dose.

The higher 7.2 mg dose may be considered only in eligible adults living with obesity, when clinically needed, after at least four weeks at 2.4 mg.

This guide explains the Wegovy UK dose-escalation schedule, how the injection is used, where it is injected, how pen dosing works, how Wegovy injection differs from tablet semaglutide products, and when higher doses or clinical review may apply. That matters because recent UK dose and formulation changes make it important to follow prescribing instructions closely and avoid incorrect dose increases or administration errors.

Key things to know

• Wegovy injection is used once a week.
• The standard starting dose is 0.25 mg. The usual step-up period lasts 16 weeks before reaching 2.4 mg.
• For an eligible adult living with obesity, treatment may later increase to 7.2 mg once weekly if clinically required.
• The dose should never be increased simply because weight is changing more slowly than expected.
• Wegovy should be used exactly according to prescribing instructions.

What Is Wegovy?

Wegovy contains semaglutide. Semaglutide belongs to a group of medicines known as GLP-1 receptor agonists. For weight management, semaglutide acts on biological pathways involved in appetite, fullness and food intake. NICE describes Wegovy as a treatment used alongside a reduced-calorie diet and increased physical activity for eligible people managing overweight or obesity.

Wegovy should not be confused with every other medicine containing semaglutide.The exact product matters because formulations, authorised uses and dosing schedules can differ.

What Are the Wegovy UK Doses?

For the injectable Wegovy treatment pathway, the main weekly doses are:

The usual Wegovy injection schedule gradually increases the weekly dose from 0.25 mg to 2.4 mg over 16 weeks. Selected adults living with obesity may be considered for the 7.2 mg dose after completing at least four weeks at 2.4 mg, if their prescriber decides that a higher dose is clinically appropriate.

Reaching a particular week of treatment does not automatically mean the dose should be increased.

What Is the Starting Dose of Wegovy in the UK?

The standard Wegovy injection starting dose is 0.25 mg once weekly.

This is the first stage of treatment. It is deliberately lower than the usual maintenance dose.The objective is to introduce semaglutide gradually rather than exposing someone to the full maintenance dose immediately.

Current MHRA guidance states that treatment begins at 0.25 mg per week before the dose is gradually increased every four weeks.

Is Wegovy 0.25mg a Maintenance Dose?

Usually not.For standard adult weight management, 0.25 mg is the introductory dose used during the first four weeks.Someone should not assume 0.25 mg is not working simply because major weight change has not occurred during the first month. The early stage is partly about tolerability, safe escalation and adapting to treatment.Wegovy results should not be judged solely from the first few injections.

What Happens After Wegovy 0.25mg?

The usual next step is: 0.5 mg once weekly during weeks 5 to 8. The dose then normally progresses in four-week stages.The complete standard escalation is 0.25 mg for four weeks, 0.5 mg for four weeks, 1 mg for four weeks, 1.7 mg for four weeks then 2.4 mg once weekly.

The MHRA uses this gradual approach specifically to help reduce gastrointestinal symptoms during dose escalation.

What Is Wegovy 0.5mg Used For?

Wegovy 0.5 mg is normally the second dose stage.Someone generally moves to 0.5 mg after completing four weeks at 0.25 mg.This stage helps continue the gradual increase towards maintenance treatment.It should not be skipped simply because the person tolerated the starting dose well.Changing the escalation schedule without clinical advice can increase adverse-effect risk.

What Is Wegovy 1mg Used For?

Wegovy 1 mg is normally used during weeks 9 to 12 of the standard escalation schedule.

By this stage, someone has typically completed four weeks at 0.25 mg and four weeks at 0.5 mg.The 1 mg stage is still part of dose escalation rather than the usual final adult weight-management maintenance dose.

What Is Wegovy 1.7mg Used For?

Wegovy 1.7 mg is normally the fourth escalation step.The usual schedule places it during weeks 13 to 16. It bridges the gap between: 1 mg and the established 2.4 mg maintenance dose.Someone experiencing significant gastrointestinal symptoms during escalation should contact their prescribing service.

Current semaglutide prescribing information allows clinicians to consider delaying escalation or returning temporarily to the previous dose when significant gastrointestinal symptoms occur. NICE documentation reflects this gradual tolerability-based approach.

What Is Wegovy 2.4mg?

Wegovy 2.4 mg is an established once-weekly maintenance dose.Under the standard escalation schedule, it is normally reached from week 17. This means someone typically spends around four months building gradually from 0.25 mg to 2.4 mg.

The maintenance stage is where longer-term treatment response becomes particularly important.

The dose should still be reviewed periodically rather than treated as something that automatically continues without clinical oversight.

Is Wegovy 2.4mg the Highest Dose in the UK?

No longer in every circumstance.This changed during 2026. The MHRA authorised 7.2 mg once weekly as the maximum weekly dose for eligible adults living with obesity when a higher maintenance dose is clinically needed.The higher dose can be considered after at least four weeks at 2.4 mg. However, the 7.2 mg pathway has narrower eligibility than standard Wegovy weight-management treatment.

What Is Wegovy 7.2mg?

Wegovy 7.2 mg is the newer maximum once-weekly semaglutide injection dose authorised in the UK for selected adults living with obesity.The MHRA first approved the 7.2 mg dose in January 2026.At that point, treatment required three 2.4 mg injections given sequentially on the same day.In April 2026, the MHRA approved a single-dose 7.2 mg Wegovy pen.

That means the full 7.2 mg weekly dose can now be delivered through one authorised single-dose injection device.

Who Can Use Wegovy 7.2mg?

The MHRA's 2026 approval applies specifically to adults living with obesity with BMI 30 kg/m² or above when the higher dose is clinically required.

The higher 7.2 mg dose does not apply to people using Wegovy for weight management who are in the overweight BMI range below 30 kg/m².

It also does not apply to treatment being used specifically for reduction of serious cardiovascular-event risk.

Therefore, someone should not assume that reaching 2.4 mg automatically means the next step is 7.2 mg.

Do You Go Directly From 2.4mg to 7.2mg?

A higher 7.2 mg maintenance dose may be considered after a minimum of four weeks on 2.4 mg once weekly. It is a prescribing decision based on individual circumstances.

The higher dose should not be self-selected because appetite has returned, weight reduction has slowed or another person is using 7.2 mg.

Clinical review comes first. Not everyone needs to move beyond 2.4 mg after they reach the maintenance dose.

Why Does Wegovy Increase Every Four Weeks?

The dose-escalation schedule is designed primarily around tolerability.

Semaglutide commonly causes gastrointestinal effects, particularly nausea, vomiting,, diarrhoea, constipation.Increasing the dose gradually gives the body more time to adapt.

Current MHRA information confirms that the Wegovy dose is increased every four weeks from the 0.25 mg starting point.

Faster escalation does not mean faster safe weight management.

Can You Stay on a Lower Wegovy Dose for Longer?

Sometimes a prescriber may adjust escalation according to tolerability.If gastrointestinal symptoms are significant, the clinical approach may involve delaying escalation, or temporarily using the previous dose until symptoms improve.This should be directed by the prescribing healthcare professional rather than done independently.A slower schedule does not necessarily mean treatment has failed.

Can You Increase Wegovy Faster Than Every Four Weeks?

Do not do this independently.The four-week stages are part of the authorised escalation structure.Increasing faster could produce greater medicine exposure before the body has had enough time to adjust.The aim is not to reach the largest number on the pen as quickly as possible.The appropriate dose is the dose prescribed within the treatment plan.

Can You Choose Your Own Wegovy Dose?

No.Wegovy is a prescription medicine.The dose depends on where you are in the escalation schedule tolerability, clinical response, BMI, treatment indication and prescriber assessment.Someone should never choose a dose based on another person's treatment ,social media, remaining pens or a desire to lose weight faster.

How Often Do You Use Wegovy?

Wegovy injection is used:

once weekly.

NICE documentation states that Wegovy can be administered once a week at any time of day and with or without meals.Using the medicine on the same day each week helps establish a consistent routine.A weekly medicine should not be used daily every few days or only when appetite feels stronger.

What Time of Day Should Wegovy Be Used?

Wegovy can be injected at any time of day.It does not have to be before breakfast, after dinner or on an empty stomach.NICE prescribing information states that semaglutide can be administered with or without meals. The most practical approach is usually to select a weekly time that is easy to remember.

Can You Change Your Wegovy Injection Day?

Yes, but the interval matters.NICE documentation states that the weekly administration day can be changed as long as at least 3 days or more than 72 hours have passed since the previous dose.Once the new day has been selected, once-weekly dosing should continue.Do not repeatedly move doses closer together simply for convenience.

Where Do You Inject Wegovy?

Wegovy is injected under the skin. This is called subcutaneous injection. Recognised injection areas include the abdomen, the thigh and the upper arm.Wegovy should not be injected into a vein or into a muscle.Before self-injecting for the first time, the patient should receive appropriate instruction from a healthcare professional.

Can You Inject Wegovy in the Stomach?

Yes.The abdomen is one of the recognised subcutaneous injection areas.The important point is that medicine goes into subcutaneous tissue, rather than deeply into muscle.Avoid repeatedly using exactly the same injection spot.Rotating sites can help reduce local irritation.

Can You Inject Wegovy in the Thigh?

Yes.The upper thigh is another recognised area for subcutaneous Wegovy administration.Some people prefer the thigh because they find it easier to see and reach.The chosen site does not mean the medicine will reduce fat specifically from that area.Wegovy acts systemically rather than locally at the injection site.

Can Wegovy Be Injected Into the Arm?

Yes.The upper arm is included among recognised injection areas.Someone who finds this position difficult to reach may prefer the abdomen or the thigh.Correct injection technique is more important than choosing one supposedly more effective area.

Does the Injection Site Change How Much Weight You Lose?

There is no reason to choose the abdomen because you want to reduce abdominal fat or the thigh because you want to reduce thigh fat.

Wegovy does not act by dissolving fat immediately around the injection.

The medicine enters the body and acts through GLP-1 receptor pathways involved in appetite and energy intake.

Choose the injection site according to the authorised instructions and practical comfort.

How Do You Use a Wegovy Pen?

Wegovy injection devices differ by dose strength. The standard doses up to 2.4 mg have been supplied in multi-dose pre-filled pens, while the newer 7.2 mg presentation uses a single-dose pen.

Always follow the instructions supplied with your specific pen. Do not assume that the steps for one device apply to another, particularly when moving between dose strengths.

What Should You Check Before Injecting Wegovy?

Before administration, check the medicine name, the prescribed strength, the pen and the supplied instructions.Make sure the pen corresponds with the dose prescribed for your current treatment stage. This matters because Wegovy injection strengths include:, 0.25 mg, 0.5 mg, 1 mg, 1.7 mg, 2.4 mg and the newer 7.2 mg presentation.Using the wrong pen can lead to an incorrect dose.

Do Wegovy Pens Contain More Than One Dose?

Device design depends on the formulation.

Standard UK Wegovy pens used for doses up to 2.4 mg have been supplied as pens containing four weekly doses.The newer 7.2 mg device authorised in April 2026 is a single-dose pen. This distinction is important for people moving between dose strengths. Do not assume every pen functions in exactly the same way.

Can You Dial a Different Dose From a Wegovy Pen?

The pen should be used only according to its authorised instructions and prescribed strength.Do not attempt to create an unofficial dose by counting clicks, estimating a partial amount or manipulating the pen.Wegovy's structured dose range exists so that treatment can be escalated predictably.

If a prescribed dose needs changing, the prescribing service should arrange the correct treatment.

What Should You Do if You Make an Injection Mistake?

If you are unsure whether the full dose was delivered the wrong strength or the pen was used incorrectly, contact the prescribing service, a pharmacist or another appropriate healthcare professional.

Do not immediately repeat the injection because you think the first attempt might have failed.

Repeating a dose could result in excessive semaglutide exposure.

What if You Forget a Wegovy Dose?

If you miss a Wegovy injection, what you should do depends on how much time has passed since your scheduled dose.

According to the UK patient information leaflet:

• If five days or less have passed since the missed dose was due, take it as soon as you remember and then continue with your usual schedule.
• If more than five days have passed, skip the missed dose and take your next injection on the regularly scheduled day.

Never take a double dose to make up for a missed injection. If you are unsure how to resume treatment, ask your pharmacist or prescribing healthcare professional.

Can You Stop Wegovy and Restart at the Same Dose?

Do not assume that restarting at the previous high dose is always appropriate after a treatment gap.

The gradual Wegovy schedule exists partly to improve gastrointestinal tolerability.

If several doses have been missed or treatment has been interrupted for a longer period, contact the prescribing healthcare professional for advice about which dose to restart and whether escalation needs to be repeated.

Restarting independently at a high dose can make gastrointestinal symptoms more likely.

What Side Effects Can Occur During Dose Escalation?

Gastrointestinal adverse effects are among the most common problems with GLP-1 treatment.

These can include:

• nausea
• vomiting
• diarrhoea
• constipation.

Symptoms can be particularly relevant when treatment starts or after the dose increases.

That is one reason Wegovy is escalated gradually rather than beginning directly at maintenance strength.

Significant or persistent adverse effects should be discussed with the prescribing service.

What Serious Symptoms Need Medical Attention?

The MHRA has strengthened safety guidance for GLP-1 medicines regarding acute pancreatitis.

Seek urgent assessment for:

• severe persistent abdominal pain
• especially if it:
• spreads towards the back
• and occurs with:
• nausea or vomiting.

The MHRA strengthened these warnings in January 2026 following reports of severe cases associated with GLP-1 and dual GIP/GLP-1 medicines.

Severe symptoms should not be assumed to be a normal part of dose escalation.

Can You Stay on Wegovy Long Term?

For people receiving semaglutide through the relevant NHS weight-management pathway, NICE advises considering whether treatment should continue if less than 5% of the initial body weight has been lost after six months.

This is a clinical review point, not a guarantee of how much weight someone should lose. The decision to continue treatment should take account of the person's response, tolerability and overall clinical circumstances.

Does Everyone Need the Highest Wegovy Dose?

No.The purpose of treatment is not simply to reach 7.2 mg.The correct maintenance strategy is determined clinically. Many people may remain on 2.4 mg once weekly.

The 7.2 mg dose is an additional option for selected adults living with obesity where a prescriber decides that escalation is appropriate.

A lower number does not automatically mean inferior treatment.

Is 7.2mg Wegovy for Everyone With BMI Over 30?

No.BMI 30 or above is part of the authorised population for the higher dose, but it does not mean every adult at or above BMI 30 requires 7.2 mg.The MHRA describes the increase as something that can be considered if needed after at least four weeks at 2.4 mg. The prescriber must decide whether the additional dose is appropriate.

Does Wegovy 7.2mg Apply to People With BMI 27 to 29.9?

Not for the higher 7.2 mg weight-management pathway.The MHRA specifically states that the 7.2 mg approval does not apply to people using Wegovy for weight management who are overweight with BMI below 30 kg/m².

Those individuals may still fall within the broader authorised Wegovy weight-management population if they meet the relevant criteria, but the higher 7.2 mg option is different.

Is Wegovy Also Available as a Tablet in the UK?

Yes, and this is another important 2026 change.

On 11 June 2026, the MHRA authorised the first GLP-1 tablet specifically for weight loss and weight management in the UK.

The tablet contains semaglutide and is marketed within the Wegovy product line.Its dosage is completely different from Wegovy injection.The tablet starts at 1.5 mg once daily and increases through 4 mg, 9 mg and 25 mg.Therefore, injection milligram doses must not be compared directly with tablet milligram doses.

Is Wegovy Injection the Same as the Wegovy Tablet?

No.They contain the same active ingredient semaglutide but differ in route, dose, frequency and formulation.Wegovy injection is given once weekly. The newer weight-management tablet is taken once daily. Someone prescribed one formulation should not use instructions intended for the other.This article's dose schedule refers primarily to the injectable Wegovy pathway.

Wegovy Injection Dose vs Wegovy Tablet Dose

The figures should never be converted directly from one route to another.

MHRA authorisation information confirms the separate oral schedule introduced in June 2026.

Can You Switch Between Wegovy Injection and Tablets?

Potentially, but this requires a clinical prescribing decision.The different routes have different doses, absorption and treatment instructions. Do not attempt to calculate your own equivalent tablet dose from an injection dose. A prescriber needs to decide whether switching is appropriate, when the new formulation should start and which dose should be used.

Does Wegovy Need Diet and Exercise?

Yes.Wegovy is authorised as an adjunct to a reduced-calorie diet and increased physical activity for appropriate weight-management populations. The medicine supports appetite regulation. It does not make nutrition and movement irrelevant. A long-term treatment plan should still consider food quality, adequate nutrition, physical activity and weight-maintenance habits.

Can You Eat Normally While Taking Wegovy?

There is no single mandatory Wegovy meal plan.However, treatment is intended to support a reduced-calorie eating pattern.Because appetite may decrease, someone should avoid assuming the less I eat, the better.Adequate nutrition remains important.If appetite becomes so low that maintaining food, fluids or normal daily function becomes difficult, contact the prescribing service.

Can You Use Wegovy With Another GLP-1 Medicine?

Do not independently combine Wegovy with another medicine acting through the same GLP-1 pathway.Using overlapping treatments can increase medicine exposure and adverse-effect risk.If an existing treatment needs to change, the prescribing healthcare professional should manage the transition.

How Should Wegovy Progress Be Reviewed?

Do not judge treatment only by how hungry you feel after one injection or how much the scale changes in one week.

Useful review areas include:

• body-weight trend
• tolerability
• dose stage
• dietary intake
• physical activity
• whether treatment remains clinically appropriate

NICE recommends considering stopping semaglutide if less than 5% of initial body weight has been lost after six months of treatment within its current NHS weight-management pathway.

Wegovy UK Doses: Key Takeaway

Wegovy injection follows a structured once-weekly dose-escalation schedule.

The standard UK progression is:

• weeks 1–4 → 0.25 mg
• weeks 5–8 → 0.5 mg
• weeks 9–12 → 1 mg
• weeks 13–16 → 1.7 mg
• from week 17 → 2.4 mg.

The gradual increase is important because it helps reduce the likelihood of gastrointestinal adverse effects while the body adapts to semaglutide.

The major UK update is the newer 7.2 mg once-weekly maintenance dose.

The MHRA authorised this higher maximum dose in January 2026 for weight management in selected adults living with obesity.

Initially, 7.2 mg required three consecutive 2.4 mg injections.

On 14 April 2026, the MHRA approved a single-dose 7.2 mg Wegovy pen, allowing the maximum weekly dose to be given as one injection.

The higher dose is not an automatic next step.It may only be considered for adults living with obesity after at least four weeks on 2.4 mg and where a healthcare professional decides it is clinically needed.

It does not apply to people in the overweight BMI range below 30 kg/m² who are using Wegovy for weight management.

Wegovy injection starts low and increases gradually rather than beginning at full maintenance strength. It is used once weekly and injected under the skin in an appropriate area such as the abdomen, thigh or upper arm. The dose should be increased only according to the prescribed schedule, and the correct pen instructions should be followed because the UK now has different device formats, including the newer single-dose 7.2 mg pen.

Another important 2026 development is that Wegovy is now also authorised as a daily semaglutide tablet for weight management. That oral formulation uses a completely different dose schedule and should not be confused with the once-weekly injection.
