Semaglutide has become a leading, doctor-supervised option for medical weight loss in Singapore. With a proven ability to regulate appetite and promote sustainable fat reduction, semaglutide is available locally as both a daily oral tablet and a once-weekly injection.
This comprehensive guide is designed to help you compare all available semaglutide-based weight loss therapies in Singapore.
You will find a side-by-side overview of the only oral tablet version of semaglutide (produced by the renowned Danish pharmaceutical company - Novo Nordisk) and the high-dose, once-weekly injectable forms that are prescribed internationally for effective, long-term weight management.
We will highlight the key differences, benefits, and important considerations between the oral tablet and weekly injection options, so you can understand which semaglutide therapy may be most suitable for your individual goals and preferences.
Whether you are seeking a needle-free solution or a doctor-recommended weekly injection, this guide will help you make an informed decision for your weight loss journey.
Semaglutide has become a cornerstone of doctor-led weight loss therapy in Singapore. As a GLP-1 receptor agonist, semaglutide offers an effective, scientifically supported solution for adults seeking medically supervised weight reduction.
Semaglutide acts by mimicking the effects of a natural hormone called GLP-1, which is involved in appetite regulation and metabolism. By binding to GLP-1 receptors in the brain and digestive system, semaglutide helps to:
Through these mechanisms, semaglutide helps individuals achieve gradual, steady weight loss when used alongside lifestyle changes such as improved nutrition and regular exercise. Both the daily oral tablet and once-weekly injection forms of semaglutide available in Singapore contain the same active ingredient, making this therapy accessible to patients with different preferences and routines.
Doctor-supervised semaglutide therapy provides a range of clinically proven benefits for weight management, including:
Semaglutide weight loss therapies are typically prescribed to adults in Singapore who:
A detailed consultation and assessment with your doctor are essential to determine suitability for semaglutide therapy. Medical professionals will review your health profile, current medications, and previous weight loss efforts to recommend the most appropriate form—either the daily oral tablet or weekly injection.
Choosing the right semaglutide therapy for weight loss in Singapore depends on several important factors, including method of administration, dosing schedule, lifestyle preferences, and specific weight loss goals.
This section provides a detailed comparison of the oral semaglutide tablet, standard-dose weekly injectable (commonly used for diabetes but often supporting weight loss), and high-dose weekly injectable (specifically formulated for significant, doctor-led weight management).
The daily oral semaglutide tablet is currently the only non-injectable GLP-1 receptor agonist for weight loss available in Singapore.
Produced by a renowned Danish pharmaceutical company Novo Nordisk, this once-daily tablet is designed for adults who seek a needle-free, convenient solution for long-term weight management.
To ensure optimal absorption, the tablet should be taken every morning on an empty stomach with a small amount of plain water, followed by a 30-minute waiting period before eating or taking other medications.
A stepwise increase in dosage is often advised to minimize gastrointestinal side effects. This oral option is suitable for patients who value convenience, travel frequently, or have a strong preference for tablets over injections.
The standard-dose, once-weekly injectable semaglutide is widely recognized for its use in type 2 diabetes management, but is also prescribed in Singapore to assist with weight loss under medical supervision.
This formulation typically ranges from 0.25 mg up to 1 mg weekly and is self-administered at home after doctor instruction.
Patients start at the lowest dose and gradually escalate to the recommended maintenance dose. While initially intended for glucose control, this standard-dose injectable is also effective for modest weight loss, particularly for adults who may have concurrent diabetes or those who do not meet criteria for higher-dose options.
This therapy is often chosen by individuals who prefer weekly injections but do not require the intensity of high-dose protocols.
The high-dose, once-weekly injectable semaglutide is specifically approved and formulated for substantial, sustained weight loss in adults with overweight or obesity.
Doses can reach up to 2.4 mg per week, making this the highest-strength prescription semaglutide available for weight management internationally. This approach involves a gradual dose escalation schedule, allowing the body to adjust and minimizing side effects like nausea or digestive discomfort.
High-dose weekly injectable semaglutide is especially suited for individuals with a BMI of 27 or above (with weight-related medical problems) or a BMI greater than 30, who require intensive, doctor-supervised support for weight reduction.
Clinical trials consistently show greater weight loss outcomes with this formulation compared to lower-dose options, especially when combined with lifestyle modification and regular medical review.
When deciding between the oral tablet, standard-dose weekly injection, and high-dose weekly injection, both patients and doctors should consider:
Discussing these options during a consultation allows your doctor to recommend the most appropriate, evidence-based semaglutide therapy tailored to your individual needs and goals.
| Therapy Type | Method of Administration | Typical Dosage Range | Most Suitable For | Common Side Effects |
| Daily Oral Semaglutide Tablet | Oral tablet, taken on empty stomach | 3 mg → 7 mg → 14 mg (stepwise) | Needle-free option, frequent travellers, adults preferring tablets | Nausea, GI upset, strict timing needed |
| Standard-Dose Weekly Injectable Semaglutide | Subcutaneous injection (at home) | 0.25 mg → 1 mg | Those seeking modest weight loss, or needing both glucose control and weight management | Nausea, GI upset, mild injection reactions |
| High-Dose Weekly Injectable Semaglutide | Subcutaneous injection (at home) | Up to 2.4 mg | Greater doctor-supervised weight loss for adults with higher BMI or weight-related issues | Nausea, GI upset (dose escalation), injection reactions |
Choosing the most suitable semaglutide therapy for weight loss is a personalised decision that should be made together with your doctor.
Both daily oral semaglutide tablets and weekly injectable options offer clinically proven support for weight reduction, but each has distinct considerations.
When deciding between oral or injectable semaglutide for weight loss, consider the following factors:
A thorough consultation with your doctor or weight loss clinic is essential. Your healthcare provider will:
Personalised, doctor-supervised care is the foundation of safe and effective weight loss with semaglutide, whether you choose a daily tablet or weekly injection.
The effectiveness of semaglutide for weight loss is well-supported by clinical research and real-world patient experience in Singapore.
Both daily oral tablets and weekly injectable formulations have demonstrated meaningful reductions in body weight for adults who require medical support to achieve lasting results.
Patients using semaglutide for weight loss typically experience gradual, steady reductions in body weight over several months. Clinical trials and local observations show that:
Success rates are influenced by factors such as individual response, consistent medication use, lifestyle changes, and medical supervision.
Patients who combine semaglutide therapy with nutrition, exercise, and ongoing doctor support often achieve the best and most sustainable results.
International clinical studies and real-world data in Singapore consistently support the use of semaglutide for medical weight management.
Published research confirms that semaglutide-based therapies lead to clinically meaningful reductions in weight, improvements in metabolic health markers, and better long-term outcomes compared to placebo or lifestyle modification alone.
Patients who remain committed to regular clinic reviews, follow medical advice, and make sustainable lifestyle changes generally see the most success with semaglutide weight loss therapy.
Understanding the safety profile of semaglutide is important for anyone considering weight loss therapy in Singapore. Both the daily oral tablet and weekly injectable options are generally well-tolerated, but patients should be aware of potential side effects and important contraindications.
The most frequently reported side effects of semaglutide therapies include:
These symptoms are usually temporary and often subside as the body adjusts to the medication. Gradual dose escalation and close doctor supervision help minimize these effects. Drinking water, eating smaller meals, and avoiding fatty foods can also help manage mild symptoms.
Although rare, some patients may experience more serious reactions, including:
Anyone experiencing these symptoms should contact their doctor or clinic immediately, or seek urgent medical care.
Semaglutide weight loss therapies are not suitable for everyone. Individuals should avoid these treatments if they have:
A thorough medical evaluation is necessary before starting any semaglutide weight loss therapy in Singapore. Your doctor will review your health history and current medications to ensure safety and suitability.
Medical weight loss options in Singapore have expanded in recent years, giving patients a wider range of doctor-supervised therapies. While semaglutide is a leading choice for both oral and injectable weight loss, other prescription options may be recommended in certain cases.
Liraglutide is a GLP-1 receptor agonist, like semaglutide, but is administered as a once-daily injection for weight loss. Both therapies work by mimicking hormones that regulate appetite and satiety. The main differences include:
Tirzepatide is a newer, once-weekly injectable medication that targets both GLP-1 and GIP receptors, offering a dual mechanism for appetite and metabolic control. Key points of comparison include:
Besides GLP-1 therapies, other doctor-prescribed options in Singapore include oral appetite suppressants (such as phentermine), fat absorption blockers (like orlistat), and multi-mechanism combination tablets.
These may be considered for specific patient profiles but often offer less sustained weight loss than semaglutide-based or dual-agonist injectables. A personalised consultation with your doctor is essential to determine which therapy best matches your health goals, lifestyle, and medical needs.
What Is the Difference Between Daily Oral Semaglutide and Weekly Injectable Semaglutide for Weight Loss?
The daily oral semaglutide tablet (internationally known as Rybelsus) is taken by mouth each morning, while the once-weekly injectable forms (such as Ozempic and Wegovy) are given as a subcutaneous injection. Both support weight loss by mimicking appetite-regulating hormones, but weekly injections like Wegovy are formulated in higher doses for more substantial weight reduction.
Who Is Eligible for Semaglutide Weight Loss Therapies in Singapore?
Semaglutide therapies—including Rybelsus tablets and once-weekly injections like Ozempic and Wegovy—are typically prescribed for adults with a BMI of 27 or above with weight-related health issues, or a BMI over 30. Your doctor will assess your medical profile, health conditions, and prior weight loss efforts to determine the most suitable option.
What Are the Expected Results From Semaglutide-Based Weight Loss Treatments?
Most patients can expect to lose 5–10% of their initial body weight within 6–12 months with consistent use of semaglutide therapies. Clinical studies show that high-dose weekly injectable semaglutide (Wegovy) can achieve even greater results. Rybelsus and Ozempic are also effective for gradual, doctor-supervised weight loss.
What Are the Most Common Side Effects of Semaglutide Weight Loss Therapies?
Rybelsus, Ozempic, and Wegovy are generally well tolerated, but the most common side effects include nausea, vomiting, diarrhoea, constipation, and mild abdominal discomfort—especially during dose escalation. These side effects are usually temporary and can be managed with dose adjustment and medical advice.
How Long Do I Need to Take Semaglutide for Weight Loss?
The recommended duration depends on your progress and weight loss goals. Many patients use Rybelsus, Ozempic, or Wegovy for 6–12 months or longer under medical supervision to maintain results and metabolic health. Ongoing doctor follow-up is important for safety and sustained success.
Can I Switch Between Oral Semaglutide Tablets and Injectable Semaglutide Therapies?
Yes. Patients sometimes switch from Rybelsus to Ozempic or Wegovy (or vice versa) depending on preference, convenience, or response to treatment. Any change in therapy should be supervised by your doctor to ensure safe dosing and optimal weight loss outcomes.
Are There Any Foods or Medications That Interact With Semaglutide Weight Loss Therapies?
With Rybelsus tablets, it is important to take the medication on an empty stomach with water and wait at least 30 minutes before eating or taking other oral medications. Ozempic and Wegovy injections have fewer food timing restrictions. Your doctor will review all your medications and supplements to avoid interactions.
What Is the Cost of Semaglutide Weight Loss Medications in Singapore?
The cost of Rybelsus, Ozempic, and Wegovy varies depending on the dosage, clinic, and availability. On average, Rybelsus may cost $300-400 a month, Ozempic may cost $600–$700 per month, while Wegovy may range from $700–$900 per month. Contact our clinic for the most up-to-date pricing.
Is It Safe to Use Semaglutide Therapies With Other Weight Loss Medications?
Semaglutide therapies should not be combined with other GLP-1 medications, such as Saxenda or Mounjaro, due to an increased risk of side effects. Always consult your doctor before starting, stopping, or combining any weight loss medications.
What Should I Do if I Miss a Dose of My Semaglutide Weight Loss Therapy?
For Rybelsus, take the missed tablet as soon as possible if the day is not over, otherwise skip and continue your normal schedule. For Ozempic or Wegovy injections, take the missed dose as soon as possible within five days; if more than five days have passed, skip the missed dose and continue as scheduled. If you miss several doses, consult your doctor for advice.
Are Results With Semaglutide Weight Loss Permanent?
Long-term weight management requires ongoing lifestyle changes. Most patients who discontinue Rybelsus, Ozempic, or Wegovy will regain some weight unless they maintain healthy eating, exercise, and follow-up with their clinic.
How Soon Will I See Results With Semaglutide Weight Loss Therapies?
Most patients start to notice a reduction in appetite and some weight loss within the first four to eight weeks of therapy. Significant results are typically seen after several months of consistent use of Rybelsus, Ozempic, or Wegovy, particularly when combined with healthy lifestyle changes and regular clinic review.
Do I Need Regular Blood Tests While Using Semaglutide for Weight Loss?
Yes. Routine blood tests may be recommended to monitor metabolic health, kidney and liver function, and blood sugar levels during treatment with Rybelsus, Ozempic, or Wegovy. Your clinic will advise on an appropriate monitoring schedule.
Can Semaglutide Be Used for Weight Loss if I Do Not Have Diabetes?
Absolutely. Although Ozempic was originally approved for diabetes and Rybelsus is a diabetes medication internationally, both medications, along with Wegovy, are prescribed by doctors in Singapore to support weight loss in adults who do not have diabetes but are overweight or obese.
Is There a Difference in Weight Loss Results Between Tablets and Injections?
Yes. Clinical studies and real-world experience suggest that weekly injections such as Wegovy generally lead to greater weight loss compared to oral tablets like Rybelsus. However, both options are effective for doctor-supervised weight reduction.
What Happens If I Stop Taking Semaglutide Weight Loss Therapy?
Stopping Rybelsus, Ozempic, or Wegovy may result in gradual weight regain unless ongoing healthy eating, physical activity, and medical follow-up are maintained. Discuss your weight maintenance plan with your doctor before making changes to your medication.
Can Semaglutide Weight Loss Therapy Be Combined With Diet and Exercise Programs?
Yes. For best results, Rybelsus, Ozempic, and Wegovy should be combined with a balanced diet, regular physical activity, and structured lifestyle support. Clinics typically provide comprehensive advice to maximise and sustain your weight loss results.
Are There Any Restrictions While Using Semaglutide Weight Loss Therapies?
Patients using Rybelsus must take the tablet on an empty stomach with water and wait before eating. There are no major food restrictions for Ozempic or Wegovy injections, but it is important to follow your doctor’s guidance on healthy eating and medication timing.
How Do I Get Started With Semaglutide Weight Loss Therapy in Singapore?
To start Rybelsus, Ozempic, or Wegovy therapy, book a consultation with our clinic. Dr Edwin or our team will assess your suitability, explain the available options, and design a personalised plan to help you achieve your weight loss goals.
