Wegovy (Semaglutide) Injections

Wegovy is MHRA-approved and is considered safe for weight loss when used under medical supervision. You might experience side-effects like nausea, vomiting, constipation or fatigue, especially at the start, but these are usually mild and usually clear up on their own. Wegovy is not suitable for those with pancreatitis, a history of thyroid cancer or severe gastrointestinal (digestive) issues.

Wegovy (semaglutide) is a GLP-1 receptor agonist that mimics a natural gut hormone to regulate your blood sugar levels and suppress your appetite.

It works by:

• Reducing appetite, making you feel less hungry.
• Reducing cravings, helping you make healthier choices.
• Lowering your ‘set point’, allowing for more weight loss before you reach a plateau.

Wegovy is most effective when combined with healthy lifestyle changes, including a balanced diet and regular exercise.

Clinical trials show that, on average, Wegovy can help people lose up to 15% of their total body weight over a year, when combined with a healthy diet and regular exercise. Results may vary based on your personal response to Wegovy, and/or your commitment to the treatment plan and lifestyle changes.

Weight loss with Wegovy tends to be gradual. You should start to notice results within the first 4 weeks, and these will continue over several months.

With Voy’s powerful combination of Wegovy, digital tracking tools and 1:1 coaching, you could lose 10%-15% of your body weight within 6 months.

Some people may notice visible weight loss within the first 4 weeks of treatment. However, the full effects tend to become more clear after a few months, depending on your personal response to Wegovy, and/or your commitment to the treatment plan and lifestyle changes.

You should not use this medication if:

• You are pregnant, breastfeeding or trying to conceive.
• You have a cancer that requires ongoing treatment or monitoring.
• You have liver, kidney or congestive heart failure.
• You have pancreatitis (inflammation of the pancreas).
• You have type 1 diabetes.
• You have diabetes eye problems (including retinopathy)
• You have a history of eating disorders (e.g., anorexia or bulimia).
• You have a history of gallbladder problems.
• You have inflammatory bowel disease (IBD) or gastroparesis.

Wegovy side effects are usually mild and temporary, especially when you first start taking it or when you increase your dose. Common side effects include:

• Nausea and vomiting
• Constipation or diarrhoea
• Headaches
• Abdominal pain
• Gas, heartburn, or belching
• Fatigue

It's normal to experience side effects when you start taking Wegovy or after increasing your dose. If you need support managing side effects, call our support line on 020 3912 9885 and press 2 to speak to a clinician within minutes (available Monday to Friday, 9 AM - 5 PM).

You might be prescribed Wegovy for weight loss if you have a BMI of 30 or above (or 27 or above with certain weight-related health conditions). For lasting weight loss, you should use Wegovy alongside a healthy diet and regular exercise.

You’ll start at a low dose and gradually increase this over time to help your body adjust and minimise side effects.

• Month 1: 0.25 mg per week
• Month 2: 0.5 mg per week
• Month 3: 1 mg per week
• Month 4: 1.7 mg per week
• Month 5: 2.4 mg per week (maximum dose)

Maintenance dose: The standard maintenance dose is 2.4 mg per week, but some people maintain weight loss on a lower dose. Your clinician will help work out the best dose for you.

You should inject Wegovy into one of the following areas:

• Abdomen – at least 5 cm away from your belly button
• Thighs
• Upper arms

Rotating your injection sites with each dose is important to minimise discomfort and reduce the risk of irritation. Always follow the instructions provided with your medication.

We suggest you self-inject Wegovy once a week into the subcutaneous fat under your skin. The injection feels like a small pinprick, but you’ll quickly get used to it. Always inject in a safe, clean environment and follow the instructions provided.

For full step-by-step instructions, read our ‘How to inject Wegovy’ guide.

• If you remember within 5 days: Take the missed dose as soon as possible.
• If it’s been 5 days or more: Skip the missed dose and continue with your next scheduled dose as planned.
• If it’s been 2 weeks or longer: Talk to your clinician to determine how to restart your treatment.

Always follow your prescribed dosing schedule and seek advice if you're unsure.

Yes, Wegovy is available in the UK through the NHS, or through a registered online pharmacy if you have a valid prescription. NHS access is typically through specialist weight management services, which may have long waiting lists.

You can also get Wegovy through Voy, where our certified medical experts can provide a prescription if you're eligible (usually for those with a BMI of 30 or above).
