Managing weight is not always as simple as eating less and moving more. For some individuals, underlying health factors, metabolic changes, and appetite regulation can make it difficult to achieve lasting results through diet and exercise alone. In such cases, a prescription-based Injectable Weight Loss Product may be considered as part of a medically supervised weight management plan to provide additional support.
One option available in Singapore is an injectable weight loss product. This treatment is only prescribed by a licensed doctor and is used alongside a healthy, calorie-controlled diet and regular physical activity. It works by targeting the body’s natural appetite signals, helping you feel full sooner and making it easier to reduce overall calorie intake.
At NU.U Aesthetics & Wellness Clinic, patients have been supported through safe, medically supervised weight management programmes for over 21 years. When appropriate, an Injectable Weight Loss Product may be considered as part of a personalised care plan, with treatment decisions guided by individual health needs, medical assessment, and long-term well-being goals.

What Is an Injectable Weight Loss Product?
An injectable weight loss product, such as semaglutide, is a prescription-based treatment designed to support weight management in adults with obesity, as well as individuals who are overweight and have related health conditions. It is not intended as a quick or standalone solution. Instead, it forms part of a structured weight management plan that includes medical supervision, lifestyle guidance, and ongoing review to support safe and sustainable progress.
This treatment tends to work best when combined with a reduced-calorie diet and regular physical activity. As an Injectable Weight Loss Product, semaglutide belongs to a group of medicines known as GLP-1 medications. These medicines act on appetite regulation pathways, helping to reduce hunger cues and support better portion control over time. When prescribed and monitored by a qualified medical professional, this approach can help individuals develop healthier eating patterns and more consistent habits as part of a long-term weight management strategy.
How It Works in the Body
The body naturally produces a hormone called glucagon-like peptide-1 (GLP-1), which plays an important role in regulating blood sugar levels after meals and signalling fullness to the brain. This hormone helps manage appetite by influencing hunger and satiety as part of the body’s normal metabolic regulation.
An Injectable Weight Loss Product is designed to work with this same biological pathway by mimicking or supporting the activity of GLP-1. By acting on existing appetite-control mechanisms, it helps regulate food intake in a controlled and medically supervised manner.
Semaglutide is an Injectable Weight Loss Product that works by mimicking the effects of the hormone GLP-1 in a sustained manner. It slows the rate at which the stomach empties, which helps prolong the feeling of fullness after meals. It also acts on appetite centres in the brain, which can reduce hunger signals and support better portion control.
As a result, some individuals may find it easier to feel satisfied with smaller meals. When used under medical supervision, an Injectable Weight Loss Product like semaglutide may support weight management efforts when combined with long-term dietary and lifestyle changes.
Treatment usually starts at a low dose of 0.25 mg once a week. This gradual introduction allows the body time to adjust and helps reduce the likelihood of side effects such as nausea or digestive discomfort. The dose is then increased step by step at intervals of about four weeks, depending on individual tolerance and medical guidance. Typical dose progression includes 0.5 mg, followed by 1.0 mg, then 1.7 mg, and eventually a maintenance dose of 1.7 mg or 2.4 mg once weekly if well tolerated.
The medication is administered using a small, pen-like injection device designed for ease of use. The injection is given just under the skin, most commonly in the abdomen, thigh, or upper arm. Instructions on proper injection technique, rotation of injection sites, and storage are usually provided by the healthcare professional to ensure safe and consistent use throughout the treatment period.
Who May Be Suitable for This Treatment
An injectable weight loss product may be considered for:
- Adults with a body mass index (BMI) of 30 or higher.
- Adults with a BMI of 27 or higher who also have weight-related conditions such as high blood pressure, type 2 diabetes, or high cholesterol.
Prescription of this treatment must follow a thorough medical assessment by a qualified doctor. During the consultation, the doctor will evaluate overall health, review medical history, assess current medications, and discuss potential risks and benefits. This ensures the treatment is appropriate and aligns with individual weight management goals, lifestyle factors, and long-term health considerations.
What to Expect From Treatment
Clinical studies have shown that people using an injectable weight loss product, together with lifestyle changes, achieved an average weight loss of around 15% over 68 weeks. This is notably higher than results seen with lifestyle changes alone.
However, results can vary from person to person, and no single outcome can be guaranteed. Factors such as age, starting weight, overall health status, medical history, and individual metabolic response all play a role in how the body responds to treatment. Commitment to healthy eating habits, regular physical activity, and consistency with lifestyle changes also significantly influences long-term outcomes.
For best results, treatment should be viewed as part of a broader weight management approach rather than a standalone solution. Combining medical support with a balanced diet, regular exercise, and sustainable lifestyle changes helps support gradual, steady progress and long-term weight control.
Possible Side Effects and Safety Considerations
Like all prescription treatments, an injectable weight loss product can cause side effects. The most commonly reported are mild and temporary, such as:
- Nausea
- Diarrhoea
- Constipation
- Stomach discomfort
This treatment is not suitable for individuals with certain medical conditions, including those with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2. It may also be inappropriate for individuals with other underlying health concerns that require careful medical consideration.
A thorough medical assessment is essential before starting treatment to ensure suitability and safety. Regular follow-up visits are also important, as they allow the healthcare provider to monitor progress, adjust the treatment plan when needed, and address any side effects or concerns that may arise over time.
Your Role in Achieving Lasting Results
An injectable weight loss product is a tool to support your journey — it cannot replace healthy habits. Your long-term success will depend on committing to balanced nutrition, staying active, and making positive lifestyle changes.
It is also important to note that stopping treatment without continuing healthy eating and physical activity habits may increase the likelihood of weight regain. For this reason, the focus is on building sustainable lifestyle changes that support long-term weight management, even after the treatment period has ended.

Frequently Asked Questions
Is the injectable weight loss product safe?
When prescribed and monitored by a qualified doctor, an injectable weight loss product has a well-established safety profile for appropriate patients. As with any prescription treatment, side effects can occur. The most commonly reported effects are gastrointestinal, including nausea, diarrhoea, vomiting, constipation, and abdominal discomfort. These reactions are often dose-related and tend to improve over time, especially when the dosage is increased gradually.
Before starting treatment, the clinician will assess medical history, current medications, and any underlying conditions to check for contraindications. Ongoing monitoring during treatment helps manage side effects, adjust dosing when needed, and ensure the injectable weight loss product is used safely and appropriately as part of a broader weight management plan.
How quickly will I see results?
Many patients notice changes in appetite within the first few weeks, especially as the dose is gradually increased according to medical guidance. These early effects often include feeling full sooner during meals or having reduced hunger between meals.
Clinically meaningful weight change usually becomes more noticeable over several months rather than immediately. Large clinical trials have reported average weight reductions of around 15% at approximately 68 weeks when treatment is combined with appropriate dietary adjustments and regular physical activity. Results can vary based on factors such as starting weight, adherence to treatment, lifestyle habits, and individual response, which is why ongoing medical review is important throughout the process.
Do I need to take it for life?
Not necessarily. The duration of use depends on individual goals, treatment response, and regular medical review. Some people may use it for a defined period, while others may require longer-term support based on their health profile and progress.
Research shows that weight regain can occur after stopping treatment, especially if lifestyle habits are not maintained. For this reason, any decision to pause or discontinue should be made together with a healthcare professional and include a clear maintenance plan. This plan typically focuses on diet, physical activity, and follow-up to help support long-term weight management results.
Can it be combined with other treatments?
In some cases, a doctor may integrate this treatment with other medical care as part of a personalised management plan, provided it is clinically appropriate and safe for the individual. Any decision to combine treatments is made on a case-by-case basis, taking into account overall health, existing medical conditions, and specific weight management goals.
General clinical guidance supports the use of anti-obesity medication alongside structured lifestyle therapy, such as dietary adjustments, physical activity, and behavioural support. When carefully supervised, this combined approach may help support more sustainable outcomes compared to relying on a single intervention alone.
Is it available over-the-counter?
No. In Singapore, this treatment is not available over the counter and can only be obtained with a valid prescription. It must be prescribed and monitored by a licensed medical professional to ensure appropriate use, dosing, and safety.
The product has been approved locally by the Health Sciences Authority (HSA). Official HSA announcements and media reports confirm that it is available strictly by prescription and not sold as an OTC product. Medical supervision is important to assess suitability, manage potential side effects, and ensure it is used as part of a structured treatment plan.
Conclusion
Injectable weight loss products such as semaglutide can play a supportive role in a medically guided weight management plan for individuals who meet appropriate health criteria.
