Why Wegovy® Benefits you need to know about Beyond weight loss, Wegovy® has benefits that set it apart from other treatments — highlighted from the latest clinical evidence.
❤️
Protects your heart — independently of weight lost In the SELECT trial, Wegovy® reduced the risk of major cardiovascular events by 20% relative risk reduction — independent of the amount of weight lost. Wegovy® is the only weight management medicine with a cardiovascular risk reduction indication.
💪
Preserves muscle mass — 84.5% of weight lost is fat MRI analysis from the STEP UP trial confirmed that 84.5% of weight lost was body fat, not lean muscle. Functional muscle capacity (measured by sit-to-stand test) was fully preserved vs placebo.
💊
No need to change your contraceptive pill Unlike some other weight loss medications, Wegovy® is not anticipated to reduce the effectiveness of oral contraceptives. No requirement to switch from pill to another contraceptive method.
🦵
Clinically meaningful knee pain relief Wegovy® is the only approved pharmacotherapy to demonstrate a clinically meaningful improvement in knee osteoarthritis-related pain alongside superior weight loss vs placebo over 68 weeks.
📅
Once a week, any time of day Wegovy® is injected once weekly, with or without food, at any time of day. The 0.25–2.4 mg FlexTouch® pens contain four weekly doses. The 7.2 mg pack contains four single-use pens, one for each week.
🌍
Trusted by over 40 million patients worldwide More than 40.8 million people worldwide have been treated with semaglutide-containing therapies since 2018. Wegovy® is manufactured by Novo Nordisk and supplied as a genuine, regulated medicine.
🏥
MHRA-licensed in the UK Wegovy® is licensed by the MHRA for weight management in adults with obesity or overweight and weight-related health conditions, and for cardiovascular risk reduction in adults with established CVD.
🧬
94% similar to your own GLP-1 hormone Semaglutide shares 94% sequence similarity with human GLP-1 — the body's natural hormone for regulating appetite and calorie intake. Targets key areas of the brain to reduce hunger and increase fullness.
About the Medicine What is Wegovy® (semaglutide)?
Wegovy® is a prescription-only weight loss injection containing the active ingredient semaglutide. It is designed to support weight loss and long-term weight management in adults who meet specific clinical criteria. Wegovy® is taken once weekly using a pre-filled injection pen and is prescribed alongside a reduced-calorie diet and increased physical activity. It belongs to a class of medicines known as GLP-1 receptor agonists (GLP-1 RAs), which mimic a naturally occurring hormone that regulates appetite and calorie intake. You can buy Wegovy online from Happy Pharmacy following a consultation and prescriber approval. Your clinician will assess whether treatment is appropriate for your individual health profile. At Happy Pharmacy, Wegovy® is prescribed by qualified clinicians and dispensed by a UK GPhC-registered pharmacy. If you’d prefer not to use injections, you can also choose a once-daily Wegovy pill.

20% relative risk reduction in cardiovascular events
🧬
GLP-1 receptor agonist Semaglutide mimics the GLP-1 hormone, targeting key areas of the brain to reduce hunger signals and increase feelings of fullness — supporting sustained weight management alongside diet and lifestyle changes.
Clinical Evidence Clinically proven Wegovy® results Wegovy® is backed by the STEP clinical trial programme — the largest weight management trial programme of its kind. Here is what the evidence shows.
~21% average weight loss in the continued-treatment analysis (STEP UP, 7.2 mg, 72 weeks)
>9/10 patients achieved ≥5% weight loss vs ~4/10 with placebo
1 in 3 patients achieved ≥25% weight loss vs 0% with placebo
20% relative risk reduction in major cardiovascular events (SELECT trial)
What the latest clinical trial showed (2025) In STEP UP, adults with obesity without diabetes taking Wegovy® 7.2 mg lost an average of 18.7% of their weight at 72 weeks in the overall analysis, compared with 3.9% on placebo. The continued-treatment analysis reported 20.7% versus 2.4%. These are trial averages, not individual forecasts. In the overall analysis, 90.7% lost at least 5% and 31.2% lost at least 25%. The 7.2 mg dose is an optional increase for eligible adults after at least four weeks on 2.4 mg, following prescriber review. Standard dose results At the usual maintenance dose of Wegovy® 2.4 mg, STEP 1 reported 14.9% average weight loss at 68 weeks, compared with 2.4% on placebo, alongside a reduced-calorie diet and increased physical activity. Our guide to Wegovy results and the weight-loss timeline explains the studies and why progress varies. Treatment and results timeline
Treatment stage Approximate timeframe What this stage means
Initial dose (0.25 mg → 0.5 mg) Weeks 1–8 Starting treatment and assessing tolerability
Dose escalation (1 mg → 1.7 mg) Weeks 9–16 Gradual dose increases if tolerated
Maintenance dose (2.4 mg) Weeks 17–68 14.9% average loss at week 68 in STEP 1; not a forecast for each week
Dose timing may be adjusted by your prescriber. Trial averages do not predict an individual’s monthly weight loss. Treatment should be accompanied by a reduced-calorie diet and increased physical activity.
Heart Health Wegovy® and cardiovascular risk reduction Obesity is a major risk factor for cardiovascular disease (CVD), which affects over 7.6 million people in the UK. More than 2 in 3 patients with a high BMI die from CVD.
Wegovy® is the only weight management medicine with a cardiovascular risk reduction indication In the SELECT trial — involving over 17,600 adults with overweight or obesity and established CVD, without diabetes — Wegovy® 2.4 mg reduced the risk of major adverse cardiovascular events by 20% relative risk reduction (1.5% absolute risk reduction) vs placebo, on top of standard of care. SELECT trial: HR 0.80; 95% CI 0.72–0.90; p<0.001. All patients treated on top of standard of care including CV risk factor management and healthy lifestyle counselling.
20% relative risk reduction in major cardiovascular events (SELECT trial)
📊
Heart protection works regardless of weight lost A prespecified analysis of the SELECT trial found that the cardiovascular benefit of Wegovy® was independent of the extent of weight loss — both patients who lost less than 5% and those who lost 5% or more experienced similar cardiovascular protection. This suggests potential mechanisms beyond weight loss alone.
Body Composition Preserving muscle while losing fat A common concern with weight loss treatments is whether muscle mass is lost alongside fat. The STEP UP trial provides reassuring evidence. Read more about how to preserve muscle on Wegovy in our guide.
Body fat lost84.5%
Lean body mass lost15.5%
MRI sub-study analysis from the STEP UP trial confirmed that when patients lost weight with Wegovy®, the vast majority of that loss came from body fat, not lean muscle. The small reduction in lean mass was not clinically significant. Muscle function was assessed using a sit-to-stand test — there were no differences in functional muscle capacity between patients taking Wegovy® and those on placebo.
Am I Eligible? Who is Wegovy® for? Wegovy® is prescribed for adults who meet specific clinical criteria based on BMI and overall health. Eligibility is confirmed during your online consultation.

  • Aged 18 or over
  • Not pregnant or breast-feeding
  • Able to follow dietary and lifestyle guidance
  • Established cardiovascular disease (for CV risk reduction indication)
✗ Wegovy® may not be suitable if…

Women's health
✅
No need to change your contraceptive pill Wegovy® does not affect how well the contraceptive pill works. You can continue taking your pill as normal — no switch to another form of contraception is needed. This is not the case with all weight loss injections.
Please note: if you experience severe vomiting or diarrhoea while taking Wegovy®, this could theoretically affect the absorption of any orally taken medicine, including the pill. If this applies to you, follow the pill manufacturer's missed-dose guidance or seek advice from your prescriber or pharmacist. Pregnancy: Semaglutide should not be used during pregnancy. If you wish to become pregnant, semaglutide must be stopped at least 2 months before a planned pregnancy due to its long half-life. Breast-feeding: Wegovy® should not be used whilst breast-feeding. Fertility: The effect of semaglutide on human fertility is currently unknown. Women of childbearing age are recommended to use contraception whilst taking semaglutide. For age-related considerations, see our guide to Wegovy for women over 40.

Treatment Plan Wegovy® dosage and treatment timeline Wegovy® is started at a low dose and increased gradually over 16 weeks to reach the maintenance dose of 2.4 mg, helping to minimise the likelihood of side effects. For eligible patients with obesity, the dose may be further increased to 7.2 mg. Read our Wegovy dose schedule guide for more detail on each stage.
Weeks Dose What this stage is for Stage
1–4 0.25 mg once weekly Starting dose to help your body adjust to treatment Starter
5–8 0.5 mg once weekly First increase; appetite control may begin to improve further Titration
9–12 1 mg once weekly Gradual step-up to support continued progress and tolerability Titration
13–16 1.7 mg once weekly Higher dose for patients who need additional appetite support Titration
17+ 2.4 mg once weekly Standard maintenance dose for ongoing weight management Maintenance
After ≥4 weeks on 2.4 mg 7.2 mg once weekly Higher dose for people with obesity (BMI ≥30) to achieve up to ~21% weight loss (STEP UP trial) STEP UP dose
⚠️
What if I don't lose enough weight? If you have been unable to lose at least 5% of your initial body weight after 6 months on treatment, your prescriber will need to review whether to continue treatment, taking into account your individual benefit-risk profile. Dose increases may be paused or delayed if gastrointestinal side effects occur.

Dispatch and delivery

Orders are typically dispatched within one working day after approval and prescription. Delivery time depends on the service and your location; estimates are not guaranteed. Your parcel is discreetly packaged and tracking is provided after dispatch. Check the delivery policy and checkout for charges and available services.

Already using Wegovy with another provider?

If you want to switch weight loss provider, read our transfer guide for the evidence needed. Your current prescription, dose and any treatment gaps will be reviewed before a prescribing decision is made.

Repeat orders and treatment support

Request your next supply before your current four-week pack runs out, allowing time for clinical review and delivery. Repeat prescriptions and dose changes are subject to a prescriber’s assessment. If you have missed several doses or taken a break, contact the team before restarting; your dose may need to change.

For help with an order, your pen or ongoing treatment, contact help@happypharmacy.co.uk or 01795 720483, Monday to Friday, 9am–5pm.

Using Your Pen How to use your Wegovy® pen Wegovy® is injected once weekly on the same day, at any time, with or without food. Check which device you have: 0.25–2.4 mg FlexTouch® pens contain four doses; the 7.2 mg pen contains one dose and is used once. Read the leaflet supplied with your pen and ask your pharmacist or prescriber to explain anything you are unsure about.

FlexTouch® pens: 0.25 mg to 2.4 mg

1
Wash hands & prepare Wash your hands thoroughly. Take your Wegovy® FlexTouch® pen from the fridge and allow it to warm slightly.
2
Attach a new needle Attach a new needle for each injection and remove both needle caps. Check the flow before the first injection with each new pen, following the leaflet. Never reuse needles.
3
Choose your injection area Inject into the abdomen (at least 5 cm from the navel), upper thigh, or upper arm (if someone else is injecting).
4
Rotate sites weekly Always rotate injection sites and leave at least one finger-width between spots to avoid skin irritation.
5
Clean skin & check dose Clean the skin with an alcohol wipe, allow to dry, and confirm the correct prescribed dose is selected on the pen.
6
Inject & hold Press and hold the dose button until the counter shows 0. Keep the needle in your skin and count slowly to 6 before removing it, as shown in the leaflet.
7
Dispose safely Remove the needle and place it immediately in your sharps container. Replace the pen cap.
8
Record your dose Note the date and dose taken. Wegovy® is given once weekly — try to inject on the same day each week.
9
Store correctly Store unused pens in the fridge (2–8°C). Once in use, the pen may be kept below 30°C for up to 6 weeks. Do not freeze. Read our guide on how to store Wegovy.

Wegovy® 7.2 mg single-use pens

A four-week pack contains four pens. Use one pen each week, then dispose of it safely in a sharps container. Each pen has a built-in needle and a preset dose, so you do not attach a needle or turn a dose selector. Follow the 7.2 mg patient leaflet and illustrated instructions: press the pen firmly against the skin and keep it in place until the yellow bar has stopped moving. Do not reuse the pen.

Store 7.2 mg pens in the fridge at 2–8°C, in their original carton to protect them from light. They may be kept unrefrigerated for up to 28 days at no more than 30°C. Discard a pen if it has been out of the fridge for more than 28 days, exposed to light or temperatures above 30°C, or frozen. The six-week in-use guidance above applies to FlexTouch® pens, not the 7.2 mg single-use device.

What Wegovy Is & How It Works

These frequently asked questions explain what Wegovy is, how Semaglutide works in the body, and what you can expect from treatment in terms of weight loss and timing of results.

What is Wegovy® used for?

Wegovy® is primarily used to support weight loss in individuals with obesity or overweight who have related medical conditions. It works by mimicking hormones that regulate appetite, helping to reduce hunger and calorie intake.

How does Wegovy work?

Wegovy contains semaglutide, which mimics the GLP-1 hormone to reduce appetite, slow digestion, and help you feel fuller for longer.

Is Wegovy approved for weight loss in the UK?

Yes, Wegovy is licensed by the MHRA for weight management in adults with obesity or overweight with related health conditions.

How much weight can you lose with Wegovy?

Clinical trials show patients can lose around 10–15% of their body weight on average when combined with diet and lifestyle changes.

How long does Wegovy take to work?

Many people notice appetite changes within the first few weeks, with more consistent weight loss developing over several months.

Dosage, Treatment & Results

How long do you take Wegovy for weight loss?

Wegovy is designed for long-term use. Many patients continue treatment for several months or longer depending on results and clinical advice.

How long can you stay on Wegovy?

There is no fixed duration. Treatment continues as long as it remains effective and well tolerated under medical supervision.

Is weight loss with Wegovy gradual?

Yes, weight loss is typically gradual and progressive, especially as doses increase over time.

What affects how much weight you lose?

Results depend on factors such as:

  • Starting weight
  • Dose
  • Diet and lifestyle
  • Consistency with injections
  • Individual metabolism

Why am I not losing weight on Wegovy?

Weight loss may slow or plateau due to factors like calorie intake, dose level, or metabolic adaptation. Your prescriber may adjust your plan.

Treatment, Stopping & Switching

What happens if you stop taking Wegovy?

Appetite may increase and some weight regain can occur if lifestyle changes are not maintained.

Can I switch from another treatment (e.g. Saxenda or Mounjaro)?

Yes, switching is possible but should be done under medical supervision with appropriate dose guidance.

Can weight loss plateau on Wegovy?

Yes, plateaus are common during weight loss. Adjusting diet, activity, or dose may help.

Delivery, Storage & Handling

How long does Wegovy delivery take?

Orders are typically dispatched within one working day after prescriber approval and prescription. Delivery time then depends on the service and your location. Tracking is provided after dispatch. Check our delivery policy for current services and charges; delivery estimates are not guaranteed.

Is Wegovy delivered in temperature-controlled packaging?

Wegovy may arrive without ice packs. The current manufacturer information supports controlled shipment below 30°C for up to 48 hours. This limit applies to delivery, not to indefinite storage at room temperature.

Place your pens in the fridge at 2–8°C when they arrive and follow the instructions supplied. If delivery is delayed, your parcel seems unusually hot, or you suspect the temperature limits have been exceeded, contact our pharmacy team before using the medicine. Do not use a pen that has been frozen. Packaging may vary with conditions.

See the official product information for FlexTouch pens and 7.2 mg single-use pens.

How should I store Wegovy?

Store unused pens in the fridge (2–8°C). Do not freeze.

How long can Wegovy be out of the fridge?

0.25–2.4 mg FlexTouch pens: after first use, keep for up to six weeks below 30°C or, preferably, refrigerated at 2–8°C. Before first use, keep refrigerated.

7.2 mg single-use pens: may be kept unrefrigerated for up to 28 days at no more than 30°C, in the original carton to protect from light. Each pen is used once and discarded. Do not apply the six-week FlexTouch rule to this device.

Do not freeze either type. Follow the leaflet supplied with your pen and ask the pharmacy if you are unsure how it has been stored.

How long does one pen last?

A 0.25–2.4 mg FlexTouch pen contains four weekly doses and lasts four weeks when used as prescribed. A 7.2 mg single-use pen contains one weekly dose; a pack of four pens provides four weeks of treatment. Dispose of each 7.2 mg pen after use.

Safety, Side Effects & Lifestyle

What side effects should I expect with Wegovy?

Common side effects include nausea, diarrhoea, constipation, and reduced appetite. These often improve over time.

Can I drink alcohol while taking Wegovy?

Alcohol is not strictly prohibited but may worsen side effects such as nausea or dehydration.

What foods should I avoid on Wegovy?

Fatty, greasy, or very large meals may worsen side effects. Smaller, balanced meals are usually better tolerated.

Can you lose weight on Wegovy without exercise?

Yes, but combining treatment with physical activity improves results and overall health.

What if I miss a dose of Wegovy?

If your injection is no more than five days overdue, take the missed dose as soon as you remember, then continue on your usual weekly day. If more than five days have passed, skip it and take the next dose on your normal scheduled day. Never take a double dose to make up for a missed injection.

If you have missed more than one dose or had a treatment break, speak to your prescriber before restarting. A lower restart dose may be needed. Follow the FlexTouch leaflet or 7.2 mg leaflet supplied with your device.

Can I travel with Wegovy?

Yes, but keep it cool during travel and follow storage guidelines.

Who should not take Wegovy?

Wegovy may not be suitable for people with certain medical conditions. Always follow prescriber guidance.

Comparisons & Alternatives

Is Wegovy the same as Ozempic?

Both contain semaglutide, but Wegovy is specifically licensed for weight loss, while Ozempic is primarily for diabetes.
