What is Wegovy?
Wegovy is a prescription weight loss injection, its active ingredient is called Semaglutide, which belongs to a group of medicines known as GLP-1s.
Wegovy is taken as a once-weekly injection, when used alongside a healthy diet and regular exercise, it can help reduce your appetite, make you feel fuller for longer and support weight loss.
It was approved by the MHRA in September 2023 for adults with obesity, or are overweight and have at least one weight-related health condition.

Who can use Wegovy?
Wegovy may be suitable for people who have:
- A BMI of 30 or above, or
- A BMI of 27 or above with a weight-related health condition
At The Family Chemist, our clinicians will review your BMI and medical history to check whether Wegovy is safe and suitable for you.
Although Wegovy is licensed for people aged 12 and over, The Family Chemist only provides this treatment to adults aged 18 and over.
How does Wegovy work?
Wegovy contains semaglutide, which works in a similar way to a natural hormone in the body called GLP-1. This hormone helps control appetite and how full you feel after eating.
By copying the effects of GLP-1, Wegovy can help you feel less hungry, reduce cravings, and feel fuller for longer. This may help you eat fewer calories and lose weight over time.
Wegovy may also support healthier eating habits by helping you feel more in control of your food choices. This can make it easier to manage hunger, reduce eating for pleasure, and build long-term habits that support weight loss.
How to inject Wegovy
Wegovy is a once-weekly injection, we advise injecting on the same day of the week. You will always start from the lowest dose of 0.25mg and increase gradually. Each Wegovy pen has 4 doses and will last for 4 weeks of treatment.
When using a Wegovy pen, always check the following and read the information leaflet from your medication pack:
Prepare – Store your new pens in the fridge. Before injecting always check the pen label to confirm it is the correct medication and inspect whether the liquid in the pen is clear and check the expiry date. Wash your hands and attach a new disposable needle to the pen.
Check the flow – Follow the directions from the information leaflet to check the flow and prime the pen. You should see a drop of solution appear on the tip of the needle. This is usually only done when you first start a new pen.
Select your dose – Select the correct dose by turning the dose selector at the end of the pen.
Inject your dose – Your dose can be injected under the skin, in the upper arm, thighs or abdomen, hold the needle in and count slowly to 6 before removing it after the dial has reached 0. Do not inject into a muscle or vein. We would advise rotating the injection site to avoid inflammation and irritation.
Dispose – Cover the needle with the cap and dispose of it in a sharps container. Do not store the pen with the needle attached.
We recommend watching this video on how to use the Wegovy pen.
Wegovy 7.2mg is slightly different from the other doses because it comes as a new single-use pen. Learn more in our guide: what is Wegovy 7.2mg?
How to Inject Wegovy 7.2mg
The new 7.2mg pen has been designed to be simpler to use than the previous Wegovy pen. You don’t need to attach a needle with the new 7.2mg pen, which makes it easier to use.
- Remove the cap from the pen
- Press the pen firmly against your skin – the abdomen, thigh or upper arm are all suitable.
- Hold it in place until the yellow bar has stopped moving (approximately 5–10 seconds).
- No needle attachment is required — simply remove the cap and inject.
- Discard the pen in your sharps bin
Note: These pens are single use, if you inject it incorrectly you won’t be able to get another dose from the same pen. You will need to inject with a new pen if you inject it incorrectly.
Read the information leaflet provided in your order so that you understand how to inject wegovy correctly.
Wegovy Dosage Information
The starting dose of Wegovy injection is 0.25mg. You can then gradually increase in a stepwise approach to the maximum weekly dose of 7.2mg. This gradual increase allows your body to adjust to the medication and ensures your safety.
You should never inject more than advised and follow the stepwise instructions. If you experience side effects, you can remain on the same dose for another month to allow your body to adjust. If side effects continue, get in touch with our clinicians or your doctor.
Wegovy Dosage
- Weeks 1-4: 0.25mg once a week
- Weeks 5-8: 0.5mg once a week
- Weeks 9-12: 1mg once a week
- Weeks 13-16: 1.7mg once a week
- Weeks 17-20: 2.4mg once a week
- Weeks 21 onwards: 7.2mg once a week
Wegovy 7.2mg dose
Wegovy 7.2mg dose became available earlier this year, but until now the dose was administered using three separate 2.4mg doses. A new, single-use 7.2mg dose is now available
If you are considering moving up to the 7.2mg dose, you must have titrated gradually from the lowest strength of (0.25mg in line with legal regulations and pharmacist advice. This applies even if you have previously used another GLP-1 medication, such as Mounjaro or Liraglutide.
As with each increase in dose, side effects may occur or become more noticeable. If side effects become difficult to manage, you should contact your healthcare provider for advice. They may advise that you reduce the dose to better manage your health. Do not make any dose changes unless advised by a clinical team.
What to expect when on Wegovy and when will I see results?
You will notice reduced appetite and feeling fuller quicker when eating food. A 72-week study on Wegovy’s use discovered that individuals using the 7.2mg dose for maintenance, achieved (on average) a 21% body weight reduction compared to the start of treatment and compared with a 2.4% body weight loss when individuals were given placebo. The STEP UP phase 3b study also found that 33.2% of participants lost ~25% of their initial body weight on Wegovy injections. 1 in 3 patients lost more than 25% body weight.
To achieve the best results, it’s important to follow a balanced diet and exercise plan. You can find out more about our additional support through our coaching service.
Can Wegovy improve my overall health?
Wegovy trials also showed that patients also noticed an improvement in their blood pressure, blood cholesterol, blood sugar control and overall cardiovascular health. MHRA has approved Wegovy as a treatment to reduce cardiovascular risk for obese or overweight individuals. Trials showed that Wegovy can reduce the risk of major cardiovascular events (such as stroke or heart attack) by 20%.
More in depth clinical trials using the 2.4mg pen found:
- 33.9% of Semaglutide patients lost over 20% of their body weight.
- 53.5% of Semaglutide patients lost more than 15% of their body weight.
- 73% of Semaglutide patients lost more than 10% of body weight.
- 84.8% of Semaglutide patients lost more than 5% of body weight.
Who cannot use Wegovy?
Whilst Wegovy is a fully licensed treatment option, it may not be suitable for everyone.
- Allergies: If you’re sensitive or allergic to semaglutide or any of Wegovy’s ingredients, you should avoid using it.
- Pregnancy and breastfeeding: Wegovy, and all GLP-1s are not safe in pregnancy or breastfeeding. You should use effective contraception during treatment and avoid conceiving whilst on Wegovy and for at least 8 weeks after your last dose. Its effects on the unborn baby are unknown and we therefore advise that you stop treatment immediately if you find out you are pregnant.
- Type 1 Diabetes or Diabetic Retinopathy: Wegovy is not an insulin substitute but may impact glucose control, this can negatively affect diabetes control and worsen eye symptoms.
- History of Thyroid Cancer: If you have a personal, or family history of thyroid cancer (Medullary thyroid Carcinoma), you should avoid using Wegovy. Trials suggest it may increase risk of developing thyroid tumors.
- Those under 18 or over 75 years of age.
- Those suffering from liver or kidney disease, diabetic retinopathy, history of pancreatitis, severe stomach or gut problems (including gastroparesis) or severe inflammatory bowel disease.
If you’re unsure whether Wegovy is right for you, please consult a healthcare professional. Always disclose all existing medications and conditions when completing your consultation.
Wegovy side effects
Wegovy can cause side effects like all medicines, although not everybody gets them. The following side effects reported are:
Very common: may affect more than 1 in 10 people
- Feeling sick (nausea), being sick (vomiting), diarrhoea, constipation, headache, abdominal pain and fatigue usually go away after a few days or weeks.
While undergoing Wegovy treatment, you may experience nausea, vomiting, or diarrhoea. These symptoms can lead to dehydration, so drinking plenty of fluids is crucial to prevent this. Staying hydrated is particularly vital if you have pre-existing kidney issues.
Common: may affect up to 1 in 10 people
- feeling dizzy
- upset stomach or indigestion
- burping
- gas (flatulence)
- bloating of the stomach
- inflamed stomach (‘gastritis’) – the signs include stomach ache, feeling sick (nausea) or being sick (vomiting)
- reflux or heartburn – also called ‘gastro-oesophageal reflux disease’
- gallstones
- hair loss
- injection site reactions
- low blood sugar (hypoglycaemia) in patients with diabetes.
Serious side effects of Wegovy
If you experience any side effects below, stop using Wegovy and see your doctor immediately.
- Pancreatitis: In rare cases, Wegovy may increase the risk of pancreatitis, which is pancreas inflammation. Symptoms may include severe abdominal pain that can radiate to the back, nausea, and vomiting.
- Gallbladder Problems: Some individuals using Wegovy may experience gallbladder-related issues, such as gallstones. Symptoms may include abdominal pain, particularly in the upper right side, and discomfort after eating fatty foods.
- Low Blood Sugar (Hypoglycaemia): While people do not primarily use Wegovy to treat diabetes, it can lower blood sugar levels. If you have diabetes or take other medications that reduce blood sugar such as insulin or sulfonylurea, there may be an increased risk of hypoglycaemia. The warning signs of low blood sugar may come on suddenly. They can include cold sweat, cool pale skin, headache, fast heartbeat, feeling sick (nausea) or hungry, vision changes, feeling sleepy or weak, nervousness, anxiety or confusion, difficulty concentrating or shaking.
- Diabetic Retinopathy – If you have diabetic retinopathy and your blood sugar improves quickly on Wegovy, this can temporarily worsen your eye condition. Your doctor should monitor you closely if this applies to you
- Increase heart rate
- Allergic reaction
The list above does not include all possible side effects, therefore it is vital that if you experience any serious side effects whilst using this medication to consult a healthcare professional and if you experience side effects not listed above, complete a MHRA Yellow Card report.
Be sure to read through the patient information leaflet before taking any new medication to familiarise yourself with the possible side effects, cautions, and contraindications. You should only take Wegovy once you have understood all the warnings and precautions. If you are concerned discuss this with your doctor or a The Family Chemist clinician.
What happens if I miss a dose of my Wegovy injection?
If you miss a dose of Wegovy, follow these guidelines:
- If you remember within 5 days or less of your scheduled injection day, inject as soon as you remember and continue with your usual schedule the next day.
- If you remember after 5 days, skip the missed dose. You can continue with your treatment from your next injection day.
- Never double-dose. If you miss multiple doses, speak with your care provider as you may need to start on a lower dose to minimise risk of serious side effects.
What are alternatives to Wegovy?
There are a range of alternative medications to Wegovy that are licensed for use in the UK. These include weight loss injections and weight loss tablets, which are available through The Family Chemist. All treatment options are provided alongside dietary and lifestyle changes.
Nevolat, Mounjaro and Wegovy all work in a similar way by mimicking GLP hormones. However, they differ in active ingredients, effectiveness, and method of administration.

If medicated options are not suitable for you, there are some alternative options to consider:
- Behavioural Therapy: Weight management often involves changes in diet and exercise habits. Behavioural therapy, either individually or in group settings, can provide valuable strategies and support for making lifestyle changes.
- Dietary Counseling: Working with a registered dietitian or nutritionist can help you develop a personalized meal plan that aligns with your weight loss goals and dietary preferences.
- Exercise Programs: Regular physical activity is essential for weight management. Consider engaging in an exercise program or working with a personal trainer to establish a fitness routine.
- Lifestyle Changes: Small but sustainable changes in your daily habits, such as portion control, mindful eating, and adequate sleep, can contribute significantly to weight loss.
- Surgical Options: In cases of severe obesity, surgical procedures like gastric bypass, gastric sleeve, or lap band surgery may be considered a last resort.
How do I store my Wegovy pen?
- Keep Wegovy out of reach of children
- Do not use after the expiry date printed on the pen and box. The expiry date refers to the last day of that month
- Store unopened pens in the fridge (2°C to 8°C). Do not freeze.
- Once in use, you can store the pen in a fridge or at room temperature (below 30°C) for up to 30 days.
- Discard pens 6 weeks after opening
- Always store the pen with the cap on, and dispose of used needles appropriately.
- Do not discard medication in household waste. Ask your local pharmacy or doctor’s surgery to dispose of any pharmaceutical waste.
Can I take Wegovy with other weight-loss medications or GLP-1 injections?
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 you must first consult your doctor and may be advised to have a sufficient treatment gap for your safety.
Wegovy Vs Ozempic
Wegovy and Ozempic both contain the same active ingredient, Semaglutide. Wegovy holds a license for weight management, while Ozempic holds a license for type 2 diabetes treatment. The Family Chemist advises against using Ozempic for weight loss as it reduces availability for type 2 diabetes patients and its use for weight loss is unlicensed.
Wegovy Vs Rybelsus
Wegovy and Rybelsus both contain the same active ingredient, Semaglutide. Wegovy holds a license for weight management, and is injected under the skin, but Rybelsus is approved for type 2 diabetes treatment and is available in an oral tablet form. The Family Chemist advises against using Rybelsus for weight loss as it reduces availability for type 2 diabetes patients and its use for weight loss is unlicensed.
What is the difference between Wegovy and semaglutide?
Wegovy is the brand name for semaglutide and the only injectable semaglutide licensed in the UK for weight loss.
Is Wegovy available from the NHS?
Yes, you may be able to get Wegovy through the NHS but the prescribing criteria differ from private services. You may be able to get Wegovy through:
- Referral to a tier 3 weight management service. You’ll need to meet the criteria and there’ll be a waiting list. How long it takes for your referral depends on your area and waiting times vary from a few months to a few years.
- Some GPs and pharmacists are receiving training to prescribe weight loss injections, but this is still in testing by the NHS so may not be available in your area. Ask your GP or community pharmacy for more information.
Can I drink alcohol while taking Wegovy?
You can drink alcohol while taking Wegovy, but it’s worth being cautious. Alcohol can affect your blood sugar levels and may worsen nausea — a common side effect of Wegovy. Alcoholic drinks are also high in calories, which can slow your weight loss progress. Speak to your clinician if you’re unsure.
Can I try for a baby or breastfeed while taking Wegovy?
No, the potential effects of Wegovy on an unborn baby is not fully understood at this point. We would advise you to use effective contraception while on Wegovy injections, and for at least 8 weeks after stopping it before trying to conceive.
It is also not advised to breastfeed while on Wegovy as it is unclear whether the medication will pass through the breastmilk.
How long does Wegovy stay in my body for?
Wegovy, or semaglutide, typically has a relatively long half-life, which means it remains active in your system for an extended period. Wegovy has a half-life of approximately one week, which means your body eliminates half of the medication in about one week.
Because of this long half-life, Wegovy can continue to affect your body for several weeks after you stop taking it. However, the precise duration can vary from person to person based on factors like metabolism and individual differences.
What comes in my Wegovy order?
Each Wegovy box contains ONE Wegovy FlexTouch pen, 4 Novofine Plus needles and a leaflet. It does not come with a sharps bin or alcohol swabs, but these are needed when administering each dose. These can all be purchased separately from ourselves or any community pharmacy.
