Wegovy (semaglutide 2.4 mg) is a prescription-only weight management injection that has generated significant interest across the UK. If you are considering it, understanding both the potential benefits and the possible risks is essential before speaking with a healthcare professional.
What Is Wegovy and How Does It Work?
Wegovy is a weekly self-administered injection that belongs to a class of medicines called GLP-1 receptor agonists. It works by mimicking a natural gut hormone that regulates appetite and blood sugar, helping you feel fuller for longer and reducing the urge to overeat.
It is approved in the UK by the Medicines and Healthcare products Regulatory Agency (MHRA) and is indicated for adults with obesity, or those who are overweight with at least one weight-related health condition such as type 2 diabetes or high blood pressure.
What Are the Benefits of Wegovy?
Clinical evidence supports a number of meaningful benefits for eligible patients.
- Significant weight loss: In clinical trials, participants lost an average of around 15% of their body weight over 68 weeks when combined with diet and exercise.
- Improved cardiovascular risk: Evidence suggests Wegovy may reduce the risk of major cardiovascular events in adults with obesity and established heart disease.
- Better blood sugar control: Improvements in HbA1c levels have been observed in patients with type 2 diabetes or pre-diabetes.
- Once-weekly dosing: The pen injection format is designed for ease of use at home.
- Clinically supported: Wegovy is backed by robust trial data, unlike many unregulated weight loss products.
What Are the Side Effects of Wegovy?
Like all medicines, Wegovy can cause side effects. Most are mild and tend to improve as your body adjusts during the dose escalation period.
Common Side Effects
- Nausea, vomiting, or diarrhoea — particularly in the early weeks
- Constipation or stomach discomfort
- Headache or fatigue
- Injection site reactions, such as redness or itching
Less Common but Serious Risks
You should seek medical advice promptly if you experience any of the following:
- Severe or persistent abdominal pain (which may indicate pancreatitis)
- Signs of gallbladder problems, including upper abdominal pain and jaundice
- Rapid heartbeat
- Symptoms of an allergic reaction
There is also a theoretical risk of thyroid tumours noted in animal studies, although this has not been confirmed in humans. Your prescriber will assess your full medical history before recommending Wegovy.
Who Is Wegovy Suitable For?
Wegovy is a prescription-only medicine. It is generally considered suitable for adults with a BMI of 30 or above, or a BMI of 27 or above where a weight-related health condition is present. It is not appropriate for everyone, including those who are pregnant, have a history of certain cancers, or have a personal or family history of medullary thyroid carcinoma.
A thorough consultation with a qualified prescriber is required before starting treatment.
How Does Wegovy Compare to Mounjaro?
Mounjaro (tirzepatide) is another prescription weight loss injection available in the UK. It works on two gut hormone receptors (GLP-1 and GIP) rather than one, and some trial data suggest it may deliver greater average weight loss than semaglutide. However, individual responses vary significantly, and both medicines have similar side-effect profiles.
The question of whether Mounjaro is safe is best answered in the context of your own medical history. Both Wegovy and Mounjaro are regulated prescription medicines, not over-the-counter products.

Frequently Asked Questions (FAQ’s)
How much weight can I lose with Wegovy?
Clinical trials found that adults using Wegovy alongside diet and exercise lost an average of around 15% of their body weight over approximately 68 weeks. Results vary between individuals and are not guaranteed.
Are Wegovy injections painful?
Most people find Wegovy injections manageable. The pre-filled pen is designed for easy self-administration. Some injection site redness or mild discomfort is possible, but typically short-lived.
How long do Wegovy side effects last?
Gastrointestinal side effects such as nausea are most common during dose escalation (the first few months). For many patients, these symptoms reduce significantly as the body adjusts to the medication.
Can I get Wegovy at a pharmacy in the UK?
Yes. Wegovy is available through registered UK pharmacies, but only with a valid prescription from a qualified prescriber. Some pharmacies, including Touchwood Pharmacy, offer weight management consultations that can support this process.
Is Wegovy the same as Ozempic?
Both Wegovy and Ozempic contain semaglutide, but they are different medicines. Ozempic is licenced for type 2 diabetes management, while Wegovy is licenced specifically for chronic weight management at a higher dose.
Is Mounjaro safer than Wegovy?
Both Mounjaro and Wegovy are prescription-only medicines approved by the MHRA and considered safe for eligible patients when prescribed and supervised appropriately. Neither is inherently ‘safer’ without the context of an individual’s full health profile. Speak with a prescriber who can assess which option, if any, is suitable for you.
