GLP-1 Medications in Singapore: Separating the Facts from the Rumours

Source: RapiDr Singapore

The National Population Health Survey 2024 reported that obesity among Singapore residents rose from 10.5% in 2019–2020 to 12.7% in 2023–2024, with the increase more pronounced among younger adults.

In Singapore, interest in GLP-1 has grown sharply. GLP-1 medications names like Ozempic, Wegovy, and Mounjaro have become some of the most talked-about drugs in the world. Social media, celebrity weight-loss stories, and a flood of online content have made these medications highly visible.

But visibility comes with misinformation.

Let’s get the basics out, what is GLP-1? ‍ ‍

GLP-1 stands for glucagon-like peptide-1, a hormone your body naturally produces after meals. It helps regulate blood sugar, signals fullness to the brain, and slows gastric emptying. GLP-1 medications work by mimicking this hormone.

Are GLP-1’s approved in Singapore?

Yes. As of time of writing, there are 3 main brands tha have been approved by Singapore’s Health Science Authorities (HSA). It is important to note that all GLP-1 medications are strictly prescrption-only medicines. Over-the-counter is not permitted in Singapore. If you have any queries, feel free to schedule a consult with our Weight Loss RapiDrs through the RapiDr App.

1. Ozempic (semaglutide, weekly injection) — HSA-approved for type 2 diabetes management

2. Wegovy (semaglutide 2.4mg, weekly injection) — HSA-approved for weight management in adults who meet specific clinical criteria

3. Mounjaro (tirzepatide, weekly injection) — available in Singapore; targets both GLP-1 and GIP receptors

So Let’s Get to Mythbusting

• Wegovy, Ozempic and Monjaro are all the same

  FALSE. While all brands contain GLP-1, but they are not the same medication and are not interchangeable. The approved indications, dosing schedules, and patient criteria differ. A doctor prescribing one is not the same as prescribing the other. When in doubt, consult our RapiDrs for more information.

• GLP-1s are a quick fix — take them for a few months and you're done.

  FALSE. GLP-1 medications are treatments for chronic conditions, not short-term solutions. These medications are most effective as part of a structured, medically guided approach that includes dietary habits and physical activity and not a substitute for lifestyle management, but work best alongside it.

• Everyone can use GLP-1

  FALSE. In Singapore, GLP-1 medications for weight management require a doctor's assessment and prescription. Suitability also depends on your existing medications, medical history, and overall metabolic health. Using these medications without proper assessment carries genuine risks.

• The Side Effects are Severe

  Gastrointestinal side effects such as nausea, constipation, and diarrhoea are the most commonly reported, particularly in the early weeks when the dose is being increased gradually. However, not everyone experiences them, and many patients find them manageable and temporary.

  Overeating or eating too quickly can worsen nausea while the body adjusts. The response is highly individual.

  A doctor can adjust your dose, advise on timing and diet changes, or consider a different medication if side effects are persistent. Stopping without medical guidance is not recommended.

• You can buy GLP-1 medications safely without a prescription

  FALSE. In Singapore, GLP-1 medications are prescription-only. Purchasing them without a valid prescription — including from unregulated online sources is illegal and dangerous. Counterfeit or unregulated products may contain incorrect doses, contaminated ingredients, or inactive substitutes. Even genuine medications used without proper medical supervision carry risks, particularly for people with underlying conditions the prescriber would otherwise screen for. If you are considering GLP-1 medications, the right starting point is a proper clinical consultation.

• GLP-1s cause muscle loss, not just fat loss.

  All methods of significant weight loss, including diet and exercise, involve some reduction in lean body mass. GLP-1 medications are not uniquely responsible for muscle loss. Clinical evidence suggests that pairing GLP-1 treatment with adequate protein intake and resistance exercise can substantially preserve muscle mass during weight loss. This is why a doctor-guided approach that includes nutritional guidance is both holistic and balanced. The medication is one part of a more complete plan.

Why Is RapiDr a Good Place to Start?

1. Understand whether GLP-1 medications are clinically appropriate for your situation

2. Get accurate information about the options available in Singapore

3. Discuss your medical history, current medications, and any conditions that may affect eligibility

4. Ask questions in a confidential, clinical setting

5. RapiDr doctors are registered with the Singapore Medical Council and held to the same standards as clinic-based GPs.

   
   Note: GLP-1 medications in Singapore are prescription-only and require a clinical assessment before being prescribed. A teleconsult can help you understand your options, but prescription decisions are always made on the basis of individual medical circumstances. RapiDr does not prescribe medications that fall outside the scope of telemedicine or without appropriate clinical justification. If a referral to a specialist or an in-person assessment is needed, your doctor will advise you accordingly.
