About Wegovy Injection
Wegovy Injection is manufactured by Novo Nordisk and contains semaglutide as the active ingredient. It is used with a reduced calorie diet and an increase in physical activity for chronic weight management in:
- Adults with a body mass index (BMI) of greater than or equal to 30 kg/m2, or 27 kg/m2 with at least one body weight-related condition, such as hypertension (high blood pressure), or type 2 diabetes mellitus
- Patients aged 12 years and over with a BMI at the 95th percentile or more for that age and sex
Wegovy Injection is a GLP-1 receptor agonist (glucagon-like peptide-1). It works by reducing appetite and calorie intake. This leads to weight loss and helps with weight management.
NowPatient offers Wegovy Injection as a treatment for weight loss only, following an online consultation with a prescribing clinician.

Answers to Popular Questions About Wegovy Injection
What is Wegovy?
Wegovy is a prescription weight management medication containing semaglutide 2.4 mg, administered as a once-weekly subcutaneous injection. It is a GLP-1 receptor agonist (glucagon-like peptide-1) manufactured by Novo Nordisk. Wegovy is licensed in the UK for chronic weight management in adults with a BMI of 30 or above (obesity), or a BMI of 27 or above (overweight) with at least one weight-related comorbidity such as type 2 diabetes, hypertension, or dyslipidaemia. It is used alongside a reduced-calorie diet and increased physical activity.
How does Wegovy work for weight loss?
Wegovy works by mimicking the hormone GLP-1, which is naturally released after eating. It acts on GLP-1 receptors in the brain’s appetite centres (hypothalamus), reducing hunger and increasing feelings of fullness (satiety). Semaglutide also slows gastric emptying, meaning food stays in the stomach longer, further reducing appetite. Clinical trials (STEP programme) demonstrated average weight loss of 12–15% of body weight over 68 weeks with Wegovy compared to approximately 2.5% with placebo, making it one of the most effective weight loss medications available.
Is Wegovy available on the NHS?
Wegovy has been approved by NICE for NHS use in England under specific criteria. It is available through specialist weight management services for adults with a BMI of 35 or above (or 32.5 for some ethnic groups) who have at least one weight-related comorbidity, and when lifestyle interventions alone have been insufficient. NHS access may be limited by service capacity and commissioning arrangements. Wegovy is also available privately through online prescribing services like NowPatient, which can offer wider access for eligible patients.
How do I inject Wegovy?
Wegovy is injected subcutaneously (under the skin) once weekly using a pre-filled pen. Recommended injection sites include the abdomen (at least 5 cm from the navel), front of the thigh, or upper arm. Rotate injection sites each week. Inject on the same day each week at any time, with or without food. Clean the injection site with an alcohol swab, pinch the skin, insert the needle at a 90-degree angle, and press the injection button. Hold for 6 seconds after the click to ensure the full dose is delivered.
What is the dose escalation for Wegovy?
Wegovy uses a gradual dose escalation over 16 weeks to reduce gastrointestinal side effects: Weeks 1–4: 0.25 mg once weekly; Weeks 5–8: 0.5 mg once weekly; Weeks 9–12: 1 mg once weekly; Weeks 13–16: 1.7 mg once weekly; Week 17 onwards: 2.4 mg once weekly (maintenance dose). This slow titration is essential to minimise nausea and other GI side effects. Do not increase the dose faster than recommended.
What should I do if I miss a dose of Wegovy?
If you miss a dose and the next scheduled dose is more than 2 days away (48 hours), take the missed dose as soon as possible. If fewer than 2 days remain before the next dose, skip the missed dose and continue with your regular schedule. If more than 2 weeks pass without a dose, contact your prescriber as you may need to restart the dose escalation. Avoid taking two doses within 48 hours of each other.
What are the common side effects of Wegovy?
Very common side effects (affecting more than 1 in 10 people) include nausea, diarrhoea, vomiting, constipation, abdominal pain, headache, fatigue, and dyspepsia. These gastrointestinal side effects are most pronounced during the dose escalation phase and typically improve over time. Eating smaller meals, eating slowly, and avoiding fatty or spicy foods can help manage nausea. Common side effects also include dizziness, flatulence, injection site reactions, and gallbladder disorders.
Can Wegovy cause pancreatitis?
There is a low risk of pancreatitis with GLP-1 receptor agonists including Wegovy. Symptoms of pancreatitis include severe, persistent abdominal pain radiating to the back, often accompanied by nausea and vomiting. If you experience these symptoms, stop Wegovy and seek immediate medical attention. Patients with a history of pancreatitis should discuss risks carefully with their prescriber before starting Wegovy. The risk is considered low but monitoring for symptoms is important.
Who should not take Wegovy?
Wegovy should not be used in people with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2 (MEN 2). It is contraindicated in pregnancy and breastfeeding. Caution is advised in patients with a history of pancreatitis, severe gastrointestinal disease (including gastroparesis), diabetic retinopathy, and severe renal or hepatic impairment. Wegovy should not be combined with other GLP-1 receptor agonists. Discuss your full medical history with your prescriber.
What happens when I stop taking Wegovy?
Weight regain is common after stopping Wegovy. Clinical trial data show that most patients regain a significant proportion of lost weight within 1–2 years of stopping treatment. This is because Wegovy addresses the biological drivers of appetite and weight regulation, and these return to baseline when the medication is discontinued. Long-term treatment may be necessary to maintain weight loss. Discuss a sustainable plan with your prescriber, including diet, exercise, and ongoing monitoring.
How should I store Wegovy?
Before first use, store Wegovy pens in the refrigerator at 2–8°C. Do not freeze. After first use, the pen can be stored at room temperature (up to 30°C) or in the refrigerator for up to 28 days. Keep the pen cap on when not in use to protect from light. Do not use Wegovy if it has been frozen or if the solution is cloudy, discoloured, or contains particles.
How can I get Wegovy?
Wegovy may be available through NHS specialist weight management services if you meet the eligibility criteria. It is also available privately through online prescribing services such as NowPatient, where a qualified UK prescriber will assess your BMI, medical history, and suitability. NowPatient provides a convenient online consultation with home delivery of the medication.
