How to Take Wegovy
The Wegovy 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.

week. 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 wegovy 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 14.9% 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.
Can Wegovy Help with Other Conditions?
Recent studies have shown that Wegovy has been proven to reduce the relative risk (RR) of cardiovascular events (such as cardiovascular death, non-fatal myocardial infarction, or non-fatal stroke) in patients with established cardiovascular disease by 20% (SELECT trial – See section 5.1 – here). Wegovy is therefore now also licensed for the use in the reduction of cardiovascular risk in adults with established cardiovascular disease.
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.
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.
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.
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, and 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 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.
