Prescription weight loss medications have become increasingly popular in Singapore for individuals who find it challenging to lose weight through diet and exercise alone.
These doctor-prescribed treatments include once-weekly and daily injectable medications, as well as oral tablets. The most recognised options are part of the GLP-1 receptor agonist class, including both weekly and daily injections containing active ingredients such as semaglutide or liraglutide.
More recently, advanced injectables using dual-action compounds like tirzepatide—which target both the GLP-1 and GIP receptors—have also become available.
Prescription weight loss medications work through clinically proven mechanisms to help regulate appetite, reduce food intake, improve satiety, and support healthier blood sugar levels. All such treatments in Singapore are prescribed and supervised by a medical doctor to ensure suitability, safety, and the best possible outcomes.
This section introduces the key types of prescription weight loss medications in Singapore and outlines how these evidence-based therapies may benefit suitable patients.
Once-weekly injectable weight loss medications are now recognised as some of the most effective doctor-prescribed options in Singapore for patients seeking clinically proven results.
These treatments belong to a group known as GLP-1 receptor agonists, with the most established option containing the active ingredient semaglutide. Patients and doctors commonly refer to these as “weekly weight loss injections,” as they only require one simple injection each week to help reduce appetite, promote satiety, and support consistent weight reduction.
An exciting advancement in this category is the introduction of dual-action GLP-1/GIP receptor agonists. These newer medications contain tirzepatide, which targets both the GLP-1 and GIP pathways to achieve even greater metabolic and weight loss benefits. Weekly injections containing tirzepatide are gaining attention for their ability to deliver significant results, especially for patients who have struggled with other methods.
These once-weekly injectable medications are typically recommended for individuals with a higher body mass index (BMI) or those who have not achieved desired results with diet and exercise alone. Initiation and ongoing management are always supervised by a qualified doctor to ensure the highest standards of safety and efficacy throughout the treatment process.
Daily injectable weight loss medications are another established option for patients in Singapore who require prescription support for weight management.
These treatments are part of the GLP-1 receptor agonist family, with the most well-known daily injectable containing liraglutide as its active ingredient. Daily injectables work by activating hormone pathways that naturally reduce appetite, slow gastric emptying, and help maintain healthier blood sugar levels.
The daily dosing schedule allows for more gradual titration and can be well-suited for patients who may benefit from a tailored approach to treatment. Some individuals may prefer daily injections if they need closer control over their response or have unique medical considerations that make a weekly injection less appropriate.
Oral prescription weight loss medications provide a convenient and non-injectable option for individuals who are seeking medical support in their weight management journey.
These medications are available only by prescription in Singapore and are designed to work through scientifically proven mechanisms such as appetite regulation, improved satiety, and metabolic support.
The following sections explain the main types of oral prescription weight loss medications available, including innovative hormone-based tablets and other pharmacological options.
The most well-known oral prescription weight loss medication available in Singapore is an oral GLP-1 receptor agonist tablet containing semaglutide. Internationally recognised as the first tablet form of this medication class, it is often sought after by patients familiar with weekly injectable weight loss therapies.
This oral semaglutide option works by mimicking natural gut hormones that regulate appetite and improve satiety, making it easier to control food intake and support gradual, sustained weight loss. It is particularly suitable for individuals who wish to avoid injections or are looking for a convenient, daily tablet regimen under doctor supervision.
For best results, treatment should be combined with lifestyle changes and regular follow-up appointments with your doctor to ensure proper dosing and monitor progress.
Beyond GLP-1 receptor agonist tablets, there are additional oral prescription options that may support In addition to hormone-based tablets, there are two main types of oral prescription medications commonly used to support weight management in Singapore: appetite suppressants and fat absorption inhibitors.
Appetite suppressants such as phentermine act on the central nervous system to help reduce hunger and control cravings. These medications can make it easier for patients to adhere to a calorie-controlled diet and achieve gradual, sustained weight loss under medical supervision.
Fat absorption inhibitors like orlistat work by blocking the absorption of a portion of dietary fat in the digestive tract. By reducing fat uptake, orlistat can help decrease overall calorie intake and promote weight loss when combined with healthy eating and lifestyle changes.
Both appetite suppressants and fat absorption inhibitors are prescription-only medications that require close monitoring by a qualified doctor. Your doctor will assess your individual health profile, weight loss goals, and potential side effects before recommending the most appropriate oral medication for your needs.
Choosing the most suitable weight loss medication involves understanding how each class works, their potential benefits, and what to expect in terms of results and side effects.
In Singapore, available prescription weight loss treatments include once-weekly and daily injectable medications, oral hormone-based tablets, and other oral agents such as appetite suppressants and fat absorption inhibitors.
This section provides a broad comparison to help patients make informed decisions under the guidance of their doctor.
The effectiveness of prescription weight loss medications can vary depending on the medication class and the individual patient’s health profile. In general, once-weekly and daily injectable GLP-1 receptor agonists, as well as dual-action GLP-1/GIP receptor agonists, have demonstrated the greatest average weight loss in clinical studies.
Oral GLP-1 tablets containing semaglutide also offer significant weight reduction benefits, while appetite suppressants like phentermine and fat absorption inhibitors such as orlistat typically result in more modest outcomes. Your doctor will help set realistic expectations and monitor your progress throughout the course of treatment.
All prescription weight loss medications should be used under the supervision of a qualified doctor to ensure safety. Injectable and oral GLP-1 medications commonly cause mild gastrointestinal symptoms such as nausea, bloating, or changes in bowel habits, which often improve over time.
Appetite suppressants may cause increased heart rate, dry mouth, or insomnia, while fat absorption inhibitors can be associated with gastrointestinal side effects like oily stools or abdominal discomfort. Your doctor will discuss the potential side effects of each medication and tailor your treatment plan to minimise risks.
Dosing frequency is an important consideration when selecting a weight loss medication. Once-weekly injectables offer the convenience of fewer injections, while daily injectables require more frequent administration but may provide flexibility in dose adjustment.
Oral GLP-1 tablets and other oral agents are taken once or multiple times per day and may appeal to those who prefer not to self-inject. Your lifestyle preferences and comfort with different dosing schedules will be considered during your consultation.
Ongoing medical supervision is essential for all prescription weight loss medications. Regular follow-up appointments allow your doctor to monitor your progress, adjust dosages as needed, address any side effects, and provide guidance on lifestyle changes to maximise results.
This personalised approach ensures that your weight loss journey remains safe, effective, and tailored to your individual needs.

The cost of prescription weight loss medications in Singapore varies based on the specific treatment, dosage, and the duration required for optimal results.
Injectable weight loss medications are generally priced higher than oral tablets due to differences in formulation and delivery methods. The total cost may also include medical assessment fees, follow-up consultations, and regular monitoring.
Prescription weight loss medications are only available through licensed medical clinics. A doctor’s evaluation is required to determine if a particular treatment is suitable and safe for you.
Most prescription weight loss medications are not covered by standard health insurance or government subsidy programmes. It is important to discuss financial considerations and long-term affordability with your doctor before starting therapy.
For a personalised cost estimate or to explore available treatment options, we recommend booking a consultation with our clinic for a detailed assessment and tailored advice.
Prescription weight loss medications are typically recommended for adults who have not achieved significant results with lifestyle changes alone, such as diet modification and increased physical activity.
Eligibility for these medications is usually based on body mass index (BMI). They are commonly prescribed for individuals with a BMI of 27 kg/m² or higher, especially if there are additional health risks like high blood pressure, high cholesterol, or type 2 diabetes.
A thorough medical assessment is essential before starting any prescription weight loss medication. Your doctor will review your overall health, medical history, current medications, and weight loss goals to determine if you are a suitable candidate.
Certain groups may not be suitable for prescription weight loss medications, including women who are pregnant or breastfeeding, individuals with specific medical conditions, or those with a history of certain drug allergies or adverse reactions.
If you are considering medical weight loss options, a consultation with an experienced doctor is the best way to assess your eligibility and develop a safe, effective treatment plan.
Prescription weight loss medications are most effective when combined with healthy lifestyle habits and behavioural support.
Adopting a balanced, reduced-calorie diet is essential to maximise the benefits of medical weight loss therapy. Your doctor or nutritionist can provide guidance on meal planning, portion control, and making sustainable dietary changes.
Regular physical activity also plays a key role in supporting weight loss and maintaining long-term results. Simple activities such as walking, cycling, or strength training can enhance metabolism and help prevent weight regain.
Behavioural strategies, including goal setting, self-monitoring, and addressing emotional eating, can further improve weight management outcomes. Many patients benefit from ongoing encouragement and support from healthcare professionals throughout their journey.
A holistic approach—combining medication, nutrition, exercise, and behavioural change—offers the highest chance of achieving and sustaining healthy weight loss.
Selecting the most appropriate prescription weight loss medication is a highly individual process that should be guided by medical expertise.
There is no single “best” weight loss medication for everyone. Factors such as your overall health, weight loss targets, underlying medical conditions, lifestyle preferences, and your response to previous treatments all play a crucial role in determining the ideal option.
A qualified doctor in Singapore will conduct a thorough medical assessment, which includes reviewing your health history, performing a physical examination, and ordering any necessary laboratory tests. This comprehensive evaluation helps ensure that the chosen weight loss medication is both safe and effective for your unique needs.
The best results are typically achieved when prescription medications are combined with tailored nutrition advice, lifestyle changes, and regular follow-up care. Ongoing medical supervision allows your treatment plan to be monitored and adjusted for optimal outcomes and minimal risk.
