Wegovy Singapore: Cost, Availability & How to Get a Prescription
Wegovy is the brand name for semaglutide 2.4 mg, a once-weekly subcutaneous injection developed by Novo Nordisk for chronic weight management. It belongs to a class of drugs called GLP-1 receptor agonists — medicines that mimic a gut hormone called glucagon-like peptide-1, which signals fullness to the brain and slows gastric emptying.
Wegovy is not the same as Ozempic. Both contain semaglutide, but Ozempic (0.5–2 mg) is approved for Type 2 diabetes. Wegovy (2.4 mg) is specifically dosed and licensed for weight management in adults with obesity or overweight with at least one weight-related comorbidity.
Yes. The HSA approved Wegovy for weight management in 2023. From late 2025, licensed medical providers — including clinics and telehealth platforms — began actively prescribing it to eligible patients.
Wegovy is a prescription-only medicine (POM) in Singapore. It cannot be purchased over the counter, and buying it from unverified online sources — including overseas pharmacies or social media sellers — is illegal and potentially dangerous. The HSA has actively removed unauthorised listings from online marketplaces. (Source: The Straits Times, November 2025)
To be prescribed Wegovy, you generally need to meet the following criteria:
Your doctor will also review your medical history, any contraindications (e.g., personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia), and any current medications.
Wegovy is not appropriate for everyone. Women who are pregnant or planning to become pregnant, or those with certain GI conditions, may not be suitable candidates.
The STEP 1 trial — the landmark Phase 3 randomised controlled trial published in the New England Journal of Medicine (Wilding et al., 2021) — enrolled 1,961 adults with obesity or overweight and at least one comorbidity. Over 68 weeks:
These results were achieved alongside a reduced-calorie diet and increased physical activity. Semaglutide is a powerful adjunct to lifestyle changes — not a replacement for them.

Typical monthly cost in Singapore: SGD $350–$1,000
The wide range reflects dosage (you start at 0.25 mg and titrate up to 2.4 mg over 16–20 weeks), clinic type, and whether consultation fees are bundled.
| Provider type | Monthly cost (approx.) |
|---|---|
| Public hospital (subsidised, eligible patients) | SGD $420 |
| Private clinic (in-person) | SGD $600–$1,000 |
| Telehealth platform | SGD $350–$700 |
Wegovy is not covered by MediShield Life or Medisave for weight management — it falls under cosmetic/lifestyle use exclusions. Some patients with obesity-related comorbidities may have partial coverage through employer health insurance; check your plan.
You need a licensed doctor to prescribe Wegovy in Singapore. There are two main routes:
Your GP, an endocrinologist, or a weight management specialist can assess your eligibility and prescribe Wegovy.
Several licensed telehealth platforms now offer Wegovy consultations in Singapore. You complete a health questionnaire, speak with a doctor via video call, and — if eligible — receive a prescription dispensed to your home.

Wegovy uses a graduated dose escalation to minimise side effects:
| Weeks | Dose |
|---|---|
| 1–4 | 0.25 mg/week |
| 5–8 | 0.5 mg/week |
| 9–12 | 1.0 mg/week |
| 13–16 | 1.7 mg/week |
| 17+ (maintenance) | 2.4 mg/week |
Most patients begin noticing reduced appetite within the first 2–4 weeks. Meaningful weight change is typically visible by weeks 8–12.
The most commonly reported side effects of Wegovy are gastrointestinal and typically mild-to-moderate:
These effects usually improve as your body adjusts. Starting at a low dose and titrating slowly is specifically designed to reduce their severity. More serious but rare side effects include pancreatitis and gallbladder disease — your doctor will discuss these during your consultation.
Q: Is Wegovy the same as Ozempic? Both contain semaglutide, but at different doses. Ozempic is approved for Type 2 diabetes (up to 2 mg). Wegovy is specifically licensed for weight management at 2.4 mg.
Q: Can I buy Wegovy without a prescription in Singapore? No. Wegovy is a prescription-only medicine in Singapore. Any website offering it without a valid prescription is illegal.
Q: How long do I need to stay on Wegovy? Wegovy is approved for long-term use. Clinical guidelines typically recommend at least 12 weeks to assess response, and most patients benefit from continued treatment for 1–2 years or longer. Weight regain is common if treatment is stopped without maintaining lifestyle changes.
Q: Does Wegovy work without diet and exercise? Wegovy is most effective when combined with a calorie-reduced diet and increased physical activity.
Q: Can I use Medisave to pay for Wegovy? Currently, Medisave does not cover Wegovy for weight management.
Q: Is telehealth Wegovy safe? Yes, when provided by a licensed Singapore-registered doctor through a regulated platform. Your physician will conduct a full medical assessment before prescribing.
Wegovy is the most clinically validated weight-loss medication now available in Singapore. With proper medical supervision, it can achieve meaningful, sustained weight reduction in eligible patients.
The key word is supervised. This is a prescription medication with a specific clinical profile, dosing protocol, and safety considerations.
