Go to FAQ
What is Wegovy?
Wegovy contains semaglutide, a glucagon-like peptide-1 (GLP-1) receptor agonist. GLP-1 is a naturally occurring hormone involved in appetite regulation and glucose metabolism.
Wegovy is prescribed as part of a broader weight management programme that may include dietary modifications, physical activity, behavioural interventions, and ongoing medical review.
How Does Wegovy Work?
Semaglutide acts on GLP-1 receptors involved in appetite and metabolic regulation.
Clinical studies suggest that semaglutide may:
- Reduce appetite in some individuals
- Increase feelings of fullness after meals
- Slow gastric emptying
- Support glucose regulation
Responses to treatment vary between individuals. The effectiveness of treatment may depend on factors such as adherence, lifestyle measures, underlying medical conditions, and treatment duration.
Wegovy Availability in Singapore
Wegovy is available in Singapore as a prescription-only medicine.
A doctor will assess whether Wegovy is appropriate based on your medical history, current medications, health status, and treatment goals. Consultations may be conducted in person or through licensed telemedicine services where appropriate.
Who May Be Suitable for Wegovy?
Eligibility is determined by a doctor following an individual medical assessment.
You may be considered for treatment if you:
- Have a Body Mass Index (BMI) of 30 kg/m² or above; or
- Have a BMI of 27 kg/m² or above together with weight-related medical conditions such as hypertension, dyslipidaemia, type 2 diabetes, or obstructive sleep apnoea.
Medical suitability depends on multiple factors and not solely on BMI.
When Wegovy May Not Be Suitable
Wegovy may not be appropriate for everyone.
Your doctor may advise against treatment if you:
- Are pregnant or planning pregnancy
- Are breastfeeding
- Have a history of medullary thyroid carcinoma
- Have Multiple Endocrine Neoplasia Syndrome Type 2 (MEN2)
- Have certain gastrointestinal disorders
- Have experienced pancreatitis
- Have known hypersensitivity to semaglutide or its ingredients
A full medical review is required before treatment is prescribed.

How to Use a Wegovy Pen
Wegovy is administered once weekly using a pre-filled injection pen. Each pen contains a fixed dose, and your doctor will provide guidance on appropriate administration and injection sites.
Proper administration of Wegovy is important to ensure the medication is used according to prescribing instructions. Your healthcare provider will demonstrate the correct injection technique during consultation.
The manufacturer provides instructional materials demonstrating preparation, administration, and disposal of the Wegovy pen.
Quick Overview of Wegovy Administration
- Step 1: Choose an injection site — abdomen, upper arm, or thigh (rotate sites each week).
- Step 2: Clean the skin with an alcohol swab and remove the pen cap.
- Step 3: Press and hold the pen firmly against the skin until administration is complete according to the product instructions.
- Step 4: Dispose of the used pen in an appropriate sharps container.
- Step 5: Store unused pens according to the manufacturer’s storage instructions (typically refrigerated at 2–8°C).
Important: Always follow your doctor’s instructions regarding injection technique and dosing. Do not reuse pens. If you miss a dose or experience concerns related to treatment, contact your prescribing healthcare provider.

How Long is Wegovy Used For?
The duration of treatment varies between individuals.
Some patients may remain on treatment for extended periods as part of ongoing weight management. Decisions regarding continuation, dose adjustment, or discontinuation should be made together with a healthcare professional.
Stopping treatment may affect ongoing weight management efforts, and patients should seek medical advice before making changes to prescribed treatment.
Clinical Research and Health Outcomes
In addition to weight management outcomes, semaglutide has been studied for its effects on a range of metabolic and cardiovascular health measures.
Clinical studies have evaluated associations between semaglutide treatment and changes in:
- Body weight
- Blood glucose markers such as HbA1c
- Blood pressure measurements
- Lipid and cholesterol profiles
- Cardiovascular outcomes in selected patient populations
The relevance of these findings varies depending on an individual’s medical history, existing health conditions, and treatment goals.
Patients should discuss the potential benefits and limitations of treatment with their healthcare provider as part of an overall weight management plan.
