Wegovy® information
Wegovy® (semaglutide) is an effective injectable weight loss drug for people with a BMI over 30. It’s also available for people with a BMI over 27 who have additional weight-related health concerns, like high blood pressure, Type 2 diabetes, heart disease, and raised cholesterol.
Wegovy® mimics a natural hormone in the gut that helps to control your appetite and make you feel fuller.
Wegovy® is an injectable medication that comes in a pre-filled pen. It should be used once weekly, on the same day. The pen is simple to use, and the needles are very small, so it’s relatively pain-free and easy to get used to.
Wegovy® can be injected in the abdomen, thigh or upper arm at any time during the day, with or without food. It’s recommended that you use it around the same time each week — this will regulate the medication’s effectiveness.
You’ll receive clear instructions with your first order, and the Wegovy® website has lots of useful information too.
This helpful video has more information about how to use Wegovy.
Wegovy® is an injectable weight loss medication suitable for people with a BMI of ≥ 30, or for people with a BMI ≥ 27 in the presence of a weight-related health concern such as high blood pressure, prediabetes or high cholesterol.
Wegovy® is also suitable for people with a BMI of ≥ 27 and established heart disease, to reduce the risk of major adverse cardiovascular events such as a heart attack, stroke, or death from heart disease.
If you have type 2 diabetes and a BMI less than 27, we can’t prescribe you Wegovy® for weight loss.
Everyone’s journey with Wegovy is unique. You’ll begin with a low starting dose (0.25 mg once a week) to help your body adjust comfortably. From there, your dose may increase gradually over time - but there’s no single “right” pace or target.
Our clinical team will check in with you regularly to see how you’re responding and feeling. Some people find they’re reaching their goals and tolerating treatment well at a lower dose, while others may benefit from stepping up. What matters most is finding the dose that works best for you — balancing comfort, results, and your personal health goals.
We’ll also review your progress to make sure Wegovy is delivering meaningful results for you before continuing treatment.
Wegovy has helped many people achieve meaningful weight loss. In clinical studies, most people lost a significant amount of weight over time.
- Over 9 in 10 people lost at least 5% of their starting body weight.
- More than 8 in 10 people lost 10% or more.
- Around 1 in 3 people lost 25% or more.
These results are averages from the STEP UP clinical trial, a 72-week study of adults with obesity using Wegovy (semaglutide 7.2mg). Individual weight loss varies, and not everyone will achieve the same results.
- A sharps bin
- An instruction leaflet
- Extra tips that can help you to lose weight
You’ll begin on a low starting dose, taken once a week. From there, you can move up gradually or stay where you feel comfortable, and your clinician will review your choice and confirm it’s safe and sustainable for you.
Over time, some people choose to reduce their dose to maintain results or manage side effects.
You’ll receive a sharps bin with your first order. This is a special waste bin that’s used to store sharps material, like needles, until it can be safely disposed of.
After every use, dispose of the needle into the sharps bin. After the 4 doses, and once the needle has been removed, the pen can be disposed of in your household waste or the sharps bin. When full, your sharps bin can be collected for disposal by your local council or exchanged for a new one at a local pharmacy.
- Wegovy should be stored under 30°C or, preferably, in a fridge (2-8°C).
- Don’t freeze your pen, or use it if it has been frozen.
- Keep the cap on when the pen isn’t in use to protect it from light.
We’re here to support you throughout your weight loss journey, offering tips to help you manage side effects and providing reassurance if you have any concerns.
While Wegovy has helped many people reach their health goals, it’s crucial to understand what to watch for along the way. Below, we’ve outlined the most common and rare side effects, along with guidance on when to seek help.
Very commonThese side effects may occur in more than 1 in 10 people and usually go away over time. They are most common when first starting Wegovy and when increasing the dose.
- Examples: feeling sick (nausea), vomiting, diarrhoea, constipation, stomach pain, headache, fatigue, dysesthesia (unusual or uncomfortable skin sensations).
These side effects may occur in up to 1 in 10 people.
- Examples: dizziness, indigestion, heartburn, bloating, burping, flatulence, injection site reactions (redness, swelling), gallstones, allergic reaction (e.g., rash, itching, and eczema), low blood pressure, hair loss, changes in sense of touch, changed sense of taste, gastritis.
In patients with type 2 diabetes, rapid improvements in blood sugar control can temporarily worsen diabetic eye disease (retinopathy), a common side effect of Wegovy. If you have this condition and notice eye problems while taking Wegovy, contact your GP or call 111 for advice.
UncommonThese side effects may occur in up to 1 in 100 people.
- Examples: kidney stones, increased heart rate, and low blood sugar (also known as hypoglycaemia).
- SERIOUS: pancreatitis. This is inflammation of the pancreas that can cause severe stomach pain which can radiate to your back that doesn’t go away. Most patients feel very ill with pancreatitis and may present with severe vomiting that does not settle. You should call 999 or attend A&E right away if you experience these symptoms.
These side effects may occur in up to 1 in 1000 people.
- SERIOUS: severe allergic reaction (anaphylaxis). This can present as difficulty breathing, swelling of lips, tongue and/or throat, difficulty swallowing, rapid heartbeat. You should call 999 or attend A&E right away if you experience these symptoms.
If you have any questions about side effects or how to manage them, we’re here to support you.

“Fantastic from start to finish”
Using Wegovy for about 4 weeks now and not only the product itself is fantastic, but the service from MedExpress is fantastic from consultation, ordering, delivery, re-ordering reminders. Also great to see the links between MedExpress and my own GP here in Northern Ireland. Would highly recommend MedExpress.
“Lost over 5kg”
Great pharmacy quick delivery. Have been using the weight loss injections for about 3 months and have lost over 5kg with hardly any exercise as I'm disabled so can't really exercise. Only side effect I'm feeling is constipation. Great great product.
“Great, really pleased”
My medication comes quickly, if I have any query questions, I can just email them and then they get back to me. I'm pleased to say that the Wegovy injections that I have are now starting to work, so I'm really happy 😁
“Injection is easy to use”
I have tried all diets this one actually works by making you feel full. I would recommend it to anyone to shed some pounds.

Wegovy® FAQs
Wegovy® is a once-weekly injection that’s given in the arm, leg or abdomen. It uses a very small, fine needle for a near-painless injection just below the surface of the skin. The Wegovy® pen comes ready to use, with a button that delivers the right amount of medication for your treatment stage. Once you’ve had the injection, remove the needle and dispose of it in a sharps bin.
Each Wegovy® pen contains 4 doses and will therefore last 4 weeks. The strength of the injection is increased every 4 weeks until the maximum dose is reached.
Wegovy is one of the most effective weight loss treatments available.In the STEP UP clinical trial, people taking Wegovy 7.2mg lost an average of around 19% of their starting body weight over 72 weeks, while those on 2.4 mg lost around 16%*.
Everyone responds differently, and higher doses can increase the risk of side effects. Your clinician will assess whether this dose is suitable for you.
*Based on a 72-week study of adults with obesity using Wegovy (semaglutide 7.2mg).
We need to assess your weight once you’ve been taking Wegovy® for around 6 months. If you’ve lost 5% of your initial weight at that assessment, you are likely to be able to continue using it for up to two years with clinical guidance.
If you have any queries or concerns at any time, you contact our support team.
If you experience symptoms such as persistent nausea, vomiting and diarrhoea with your current Wegovy® dose, speak to our customer care team for advice. We may recommend delaying your next dose increase for a few more weeks to see if that helps improve your tolerance. We can also give you tips to help manage any symptoms and get maximum benefit from the medication. It’s important to not increase your Wegovy® dose until your body is ready, so make sure you contact MedExpress if you have persistent side effects.
If you are concerned or alarmed by your symptoms review the patient information leaflet or seek medical attention
Always carry your Wegovy® pen in your hand luggage. Never place it in your checked baggage, as the aircraft hold can expose it to freezing temperatures that could damage the medication. Use a travel cooler to help keep your Wegovy® pen cold, especially if you’re travelling for extended periods in warm climates.
Unopened Wegovy® pens should be stored in a refrigerator between 2°C and 8°C. If that’s not possible, the pen can be kept at room temperature (up to 30°C) for up to 28 days. It’s important not to use any pen that has been exposed to temperatures outside this range.
To pass through airport security smoothly, make sure you carry your prescription with your name on it, along with the original box your medication came in. Carry your passport as your primary ID, and consider having extra proof of address (such as a utility bill) on hand in case further verification is requested.
Airline policies on travelling with medication can vary, so it’s best to contact your specific airline ahead of time to check what’s required for carrying medication on board.
If a dose is missed, it should be administered as soon as possible, within 5 days after the missed dose. If more than 5 days have passed, the missed dose should be skipped, and the next dose should be taken on the regularly scheduled day. From there, you can continue the once weekly dosing schedule.
Yes. A major clinical trial found that Wegovy reduces the risk of heart attack, stroke and death from heart disease by up to 20% in people living with obesity or who are overweight and have pre-existing heart disease — even if they don’t have diabetes.

Wegovy can support heart health by:
- Lowering blood pressure.
- Reducing ‘bad’ cholesterol and triglycerides.
- Improving ‘good’ cholesterol.
- Reducing inflammation, a key driver of heart disease.
- Promoting weight loss, which reduces strain on the heart.

People with overweight or obesity that have pre-existing heart disease.
For example, if you are living with obesity or are overweight (BMI ≥ 27), and have previously had a heart attack, a stroke or poor blood flow to the limbs, you may be eligible for treatment.
Wegovy should not be used during pregnancy.
If you are planning to become pregnant, discontinue Wegovy at least two months in advance.
If you are of childbearing age and sexually active, you should use contraception while taking Wegovy. You can use oral contraceptive pills, non-oral methods such as the implant or IUD, or barrier methods like condoms.
Wegovy does not impact the effectiveness of the oral contraceptive pill.
As Wegovy should not be used during pregnancy, women of childbearing age should use effective contraception whilst using Wegovy. This includes the oral contraceptive pill, condoms or non-barrier methods.
If you experience severe diarrhoea that lasts for over 24 hours, or vomiting within three hours of taking your oral contraceptive pill, you may need a repeat dose of your oral contraceptive pill. Contact your GP or call 111 for medical advice if this occurs.
If you experience persistent vomiting or diarrhoea, consider using a non-oral contraception method. Contact your GP to discuss your options.
If you are planning to become pregnant, it is recommended that you wait at least two months after your last dose of Wegovy to begin trying.
Wegovy should not be used while breastfeeding. While we don’t know for sure how Wegovy could affect a breastfed baby, a risk can’t be ruled out.
