There are also multi-month bundles available for higher strengths, to lower your weekly cost.
Some patients choose to maintain at 1mg for affordability, but maximum weight loss is achieved at the 2.4mg dose. This is reached through a 5-step titration, with fewer steps than other alternatives.
0.25mg – Starter Dose
This is the starter dose, which is used for the first 4 weeks to allow your body to adjust.
0.5mg – Titration Dose
This dose follows 0.25mg and continues the safe titration process.
1mg – Effective Dose
Patients typically begin to notice more significant weight loss at this stage.
1.7mg – Titration Dose
This dose should only be used after titration. This dose is often associated with more visible progress.
2.4mg – Maintenance Dose
This is the full maintenance dose, where maximum weight loss is typically achieved.
How to Take Wegovy
The dose is increased every 4 weeks for 16 weeks. This means that patients take a 0.25mg once weekly dose for the first 4 weeks and gradually increase it until they reach the maintenance dose of 2.4 mg once weekly from week 17 onwards.
This gradual increase is important because it minimises the risk of side effects. If side effects do occur, most will be experienced during the dose-escalation phase before improving.
It can be taken at any time of day and can be taken with or without meals.
Many patients ask where it should be injected. The advice is it should be injected subcutaneously into the abdomen, thigh or upper arm.
The injection site should ideally be rotated, to avoid a single area being used.

Is Wegovy Effective for Weight Loss?
Clinical trials have shown that Wegovy treatment resulted in a statistically significant reduction in body weight compared to placebo after 68 weeks. One trial showed that people taking Wegovy had a mean change in body weight of 17% compared to 2.4% in the placebo group.
The results also showed that, after 68 weeks, 83.5% of patients lost 5% or more of their body weight. In the placebo group, 31.1% of patients lost 5% or more of their body weight.
Another clinical trial also showed a statistically significant reduction in body weight vs placebo.
The National Institute for Health and Care Excellence (NICE) has recommended Wegovy for weight management for those living with obesity due to the highly positive trial results.

Wegovy vs Placebo Trial Results
Can Wegovy Help with Other Conditions?
While Wegovy (semaglutide) has shown great results for weight loss, research shows it might have additional benefits.
The SELECT [1] study, conducted world-wide with over 17,000 patients, aimed to demonstrate Wegovy’s ability to reduce a patient’s chances of experiencing a repeat cardiovascular event (such as a heart attack or stroke).
The study appeared to be successful, showing a 20% risk reduction (SELECT trial – See section 5.1 – here) – so you are 20% less likely to have a heart attack/stroke if you have had one previously, independent of weight lost.
This shows that Wegovy has specific beneficial properties on the heart.
So, if you have cardiovascular disease, such as a previous heart attack or stroke, and are in two minds as to which weight loss option is for you, this may be a point of difference.
If you have any questions about our treatment options, and their benefits, please get in touch with our clinical team.
Contraindications & Drug Interactions
This medicine is not suitable for anyone who has had an allergic reaction to semaglutide or any of the other ingredients in the injection.
Wegovy can cause digestive system side effects like vomiting and diarrhoea. These side effects can increase the risk of dehydration, so you should make sure that you drink enough fluids. This is even more important for people with kidney problems.
An uncommon side effect that may be experienced is pancreatitis. If you notice any symptoms of pancreatitis, such as severe stomach pain, stop using Wegovy and see a doctor straight away. You can read more about pancreatitis symptoms on the NHS website.
People with diabetes should not use Wegovy as a substitute for insulin. It can also increase the risk of getting low blood sugar levels when taken with other diabetic medicines. See section 2 of the patient information leaflet for a full list of warnings.
Wegovy has not been shown to affect the oral hormonal contraceptive pill. Other weight loss drugs reduce the effectiveness of oral hormonal contraceptives, so additional barrier methods should be used at each titration/new dose for 4 weeks. This is not required for Wegovy.
Some patients on GLP-1 treatments are concerned about contraception, but Wegovy doesn’t require additional barrier methods and has fewer interactions with narrow therapeutic index medicines.
This medication is not suitable for anyone experiencing diabetic retinopathy. Speak to your doctor before using Wegovy if this applies to you.
Wegovy and Pregnancy
It should not be used in pregnancy because it may harm the foetus. Wegovy should be stopped at least 2 months before a planned pregnancy. You should not use this medicine if you are breastfeeding.
Wegovy Side Effects
As with all medicines, some people may experience side effects from the treatment. Not everyone will get them and a majority will be mild. Only 5.3% of patients in one clinical trial stopped Wegovy due to side effects.
The most common Wegovy side effects are:
- Headache
- Vomiting
- Diarrhoea
- Constipation
- Nausea
- Abdominal pain
- Fatigue
These side effects usually improve over time as your body gets used to the medicine.
Gradually increasing the dose every 4 weeks helps to reduce the risk of experiencing these side effects. If you find your side effects are severe or aren’t improving, ask your doctor or pharmacist for advice.
See section 4 of the Wegovy patient information leaflet for a complete list of possible side effects.
You can also read our Wegovy side effects guide, for advice on how to manage the most common side effects.
Wegovy Alternatives
There are many alternative weight loss treatments available in the UK, including Orlistat and its branded equivalent Xenical.
Saxenda is the closest medicine to Wegovy currently licensed for weight loss in the UK. It works in the same way and is manufactured by the same company, Novo Nordisk. Saxenda is injected once daily into the abdomen, thigh or upper arm.
Mounjaro is another injectable weight loss treatment now available in the UK. It works in a similar way to Wegovy but contains a different active ingredient, tirzepatide. Tirzepatide is a dual agonist GLP-1/GIP. Mounjaro is taken once weekly and has been shown to help patients achieve significant weight loss.
Ozempic is also available to buy from some UK weight loss clinics. Ozempic also contains Semaglutide, the same active ingredient that’s in Wegovy. However, the treatment is licensed for use in diabetes. While it is legal to prescribe it for weight loss, we currently choose not to do so, due to the possible impact on diabetic patients who require this medication.
There is not currently a generic form of Wegovy or Mounjaro – these treatments are too new to be replicated. Unlike Wegovy and Mounjaro, generic drugs that are equivalent to many medications are available through our online store.
You can visit our online doctor weight loss clinic to see what weight loss options are available to you.
Wegovy is a weight loss injection that is taken weekly and contains 4 doses. It contains the active ingredient semaglutide, which works to make you feel fuller for longer by mimicking a hormone that is usually released after eating. You can lose an average of 15 to 17% of your starting weight when taking Wegovy alongside healthy lifestyle changes to your diet and exercise routines. As a result, Wegovy can also improve heart health and help prevent cardiovascular disease.
