How Wegovy works
Wegovy contains the active ingredient semaglutide, which mimics a hormone your body produces called GLP-1, which controls hunger and helps you feel fuller after eating. It helps with weight loss by:
- Reducing feelings of hunger
- Reducing cravings
- Making you feel fuller for longer

Wegovy dosage schedule
Most people start at the lowest dose of Wegovy, then gradually increase in a stepwise approach to the maximum weekly dose; this is known as titration. This process allows your body to adjust to the medication. Below is the usual dosage schedule:
Weeks 1-4: 0.25mg weekly
Weeks 5-8: 0.5mg weekly
Weeks 9-12: 1mg weekly
Weeks 13-16: 1.7mg weekly
Weeks 17-20: 2.4mg weekly (usual maintenance dose)
Weeks 21 onwards: 7.2mg weekly (if needed, maximum dose)

How to inject Wegovy
It’s easy to use Wegovy injections as part of your weekly routine and your order comes with instructions to help you use it correctly:
- Choose your injection day – take Wegovy at the same time and day each week that works with your schedule
- Prepare your pen – take the cap off the pen and check that the liquid is clear and colourless
- Attach a new needle – push and twist the needle until it’s firmly in place
- Pull off the outer needle cap (keep this for later), then pull off the inner needle cap and throw away the inner needle cap
- Select your prescribed dose – turn the dose selector to your prescribed dose
- Choose an injection site – under the skin, in the upper arm, thighs or abdomen – ensure to rotate injection sites
- Apply to the chosen injection site – press and hold the dose button until the dose selector has reached 0. Count to 6 before removing the needle
- Dispose of the needle safely – remove the needle and put it into your sharps bin, then place pen cap back onto your Wegovy pen
Read our guide on how to inject Wegovy for detailed instructions on how to inject.
Using Wegovy 7.2mg
The Wegovy 7.2mg pen is designed as a single-use pen with a built-in needle. When you order 7.2 mg, you’ll get four single-dose pens. To inject, remove the cap, press the pen against your skin and hold until the yellow bar stops moving.
How to store your Wegovy pen
- When it arrives: Put your Wegovy pen in the fridge, between 2-8°C
- Once opened: It can be kept at room temperature (below 30°C) for up to 30 days
- Don’t use Wegovy after the expiry date printed on the pen and box
Always read the information leaflet provided in your order so that you understand how to inject Wegovy correctly.
Travelling with Wegovy
If you’re travelling with Wegovy, put your pens in your hand luggage rather than checked baggage where temperatures can fluctuate. If you’re travelling to somewhere hot, use a cooling case to keep the medication at the right temperature.
Switching to Wegovy
If you’re already on a weight-loss medication like Mounjaro, you may be able to switch to Wegovy weight loss injections without starting at the lowest dose. Our clinicians will review your current medication, dosage, and how you’re tolerating it, then recommend a Wegovy dose.
Complete an online consultation so that we can help you with switching

Switching from Wegovy tablets
Wegovy tablets and injections contain the same active ingredient, semaglutide, so switching is simpler.
If you’re currently taking Wegovy tablets, our clinical team will review your dose, treatment history and how you’ve responded to the medication before recommending a suitable injection dose.

Switching from another weight loss treatment
If you’re taking liraglutide, Foundayo or another weight-loss medication then our clinicians will advise you on taking your last dose, when to start Wegovy and which dose to start on.
Already on Wegovy with another provider?
You can usually carry on at your current dose. You’ll need to provide the following as evidence:
- a photo of the pharmacy label on your medicine box, showing your name, the medicine, the dose and the date
- a copy of your prescription or order confirmation from your previous provider
FAQs
What if I miss my Wegovy injection?
If you remember within 5 days of your injection day, take it as soon as you remember and continue your schedule. Never double up on a dose to make up for a missed dose.
If it’s been more than 5 days since your injection day, then continue your treatment from your next injection day.
If you miss multiple doses, get in contact with us as you may need to start on a lower dose to minimise risk of serious side effects.
Can I drink alcohol while taking Wegovy?
You can drink alcohol while taking Wegovy, but you should be cautious. Alcohol can affect your blood sugar levels and may worsen side effects such as nausea. Alcoholic drinks are also high in calories, which can slow your weight loss progress.
Wegovy and heart health
Wegovy is licensed in the UK to help lower the risk of heart attack and stroke. It has also been shown to improve blood pressure, cholesterol, and blood sugar levels.
The SELECT study found that people who already had heart disease and were overweight but didn’t have diabetes were 20% less likely to have a heart attack and stroke when taking Wegovy than those who weren’t.
What are alternatives to Wegovy?
- Mounjaro (tirzepatide) – a once-weekly injection with which you can lose up to 22% of your body weight
- Wegovy tablets – a once-daily tablet from the makers of Wegovy with similar weight loss results, perfect for those who don’t like injections
- Foundayo – a once-daily tablet that can be taken at any time of the day, with or without food, making it easier to fit into your daily routine
- Liraglutide – a daily injection which can help you lose up to 11% of your body weight

Wegovy Vs Ozempic, Rybelsus and semaglutide
Wegovy, Ozempic and Rybelsus all contain the same active ingredient, semaglutide, but they’re licensed for different things. Wegovy is the only one licensed in the UK for weight loss.
- Wegovy is a weekly injection, licensed for weight management
- Ozempic is also a weekly semaglutide injection, but it’s licensed to treat type 2 diabetes
- Rybelsus is semaglutide in a daily tablet, again licensed for type 2 diabetes
If you’d prefer a tablet, the licensed oral option is Wegovy tablets, which use semaglutide and are approved for weight loss.
Can I take Wegovy with other weight-loss medications?
No. It can be dangerous to take multiple weight-loss medications at the same time. We cannot provide Wegovy if you are already on other treatments. You can switch between treatments, but we may advise a treatment gap for your safety.
Is Wegovy available on the NHS?
Yes, but it will be harder to get Wegovy on the NHS than via a private pharmacy for the following reasons:
Your GP can’t prescribe it, but they can refer you to a specialist weight management service
The criteria are stricter; you’ll usually need a BMI of 35 or more with at least one weight-related health condition
Waiting times for treatment can be months or years
If you’d rather not wait, you can check your eligibility for Wegovy treatment via an online consultation or browse our weight loss treatments.
How long does Wegovy stay in your system for?
Wegovy has a half-life of approximately one week. This means that around half of the medication remains in your body seven days after your last dose.
This means it can take 5 to 7 weeks for Wegovy to leave your system completely after your last injection.
