Is there a GLP-1 that is not an injection?

Yes: one oral GLP-1, Rybelsus (oral semaglutide), is registered in Singapore, but for type 2 diabetes, not weight management. Using it for weight is off-label, a decision Dr Quek makes with you at a consultation. At GetLean it costs from S$288 a month (S$388 depending on dose), all-in.

In Singapore, tirzepatide is registered as Mounjaro, and semaglutide injection as Wegovy for weight management and as Ozempic for type 2 diabetes. Whichever medicine is prescribed, GetLean plans the exit from the first consultation. Coming off GLP-1 in Singapore: what happens and how to plan sets out how.

Registered indication: what the regulator has approved a medicine to be used for. A medicine can be perfectly legal, stocked in Singapore pharmacies and prescribed every day, and still not be approved for the purpose you are asking about. Availability and indication are two different things.

What is actually registered here

Singapore's register of therapeutic products lists an oral form of one GLP-1 medicine, in three tablet strengths, alongside the injectable semaglutide and tirzepatide products. All are prescription-only (HSA register).

The Singapore product information for that oral product states its indication: the treatment of adults with insufficiently controlled type 2 diabetes mellitus, to improve glycaemic control as an adjunct to diet and exercise (Singapore product information).

There is no weight-management indication in it. Not a restricted one, not a conditional one — the indication is diabetes.

The tablet is oral semaglutide, sold as Rybelsus, at 3 mg, 7 mg and 14 mg (HSA register). It is registered in Singapore for type 2 diabetes only, so prescribing it for weight is off-label.

A second GLP-1 tablet, orforglipron (Foundayo) from Eli Lilly, is approved in the United States and the United Kingdom (Drugs@FDA; MHRA) but is not registered in Singapore, so no doctor here can prescribe it (HSA register).

Retatrutide and orforglipron are not registered in Singapore, and GetLean does not prescribe or supply them. GetLean does prescribe and supply HSA-registered GLP-1 medications, after a consultation with Dr Quek.

Why "it exists" and "you can have it" are different questions

Because a registered indication is what a medicine has been assessed and approved to do.

A doctor may prescribe a medicine outside its registered indication. That is a recognised part of medical practice, it has a name — off-label prescribing — and it is a judgement made about one patient, with their history in front of the doctor, weighing what is known against what is not. It is not a general permission.

The distinction matters here more than usual. The tablet's registration covers diabetes, so a weight-management use sits outside it: an off-label decision, made by a doctor for one patient, at a consultation.

So the accurate answer to "can I have the tablet instead" is: that is a question for a doctor about you specifically, and the answer is not a menu item this or any other website can hand out.

What you may have read from overseas

Almost certainly this: the current United States labelling for semaglutide covers an oral tablet presentation alongside the injection, and there it does carry a weight-management indication (US prescribing information).

That is real, it is current, and it has no standing in Singapore. Regulators approve medicines independently, and an American approval does not extend here any more than a Singapore one extends there. What applies in Singapore is the Singapore registration, and for the oral product that registration is for type 2 diabetes (Singapore product information).

This is worth naming precisely because the overseas material is easy to find and reads as though it settles the question. It settles a different country's question.

The two forms are not simply the same medicine in a different shape

Worth knowing, because "just give me the tablet version" assumes an equivalence that does not hold.

The injectable products are given once weekly (product information). The oral presentation described in the United States labelling is taken once daily, on an empty stomach, with water and no other liquid (US prescribing information).

So the oral route is not the same commitment with the needle removed. It is a daily medicine with a fasting requirement attached to every dose, against a weekly injection that the labels state can be taken at any time of day, with or without meals. Which of those is easier to live with is genuinely personal, and people who assume the tablet is straightforwardly the lighter option are sometimes surprised.

None of that changes the registration position in Singapore. It is here because "can I just have the tablet instead?" is a question about living with a daily medicine as much as about registration.

What are the side effects of the GLP-1 tablet?

The most common side effects in the tablet's US label were nausea, abdominal pain, diarrhoea, decreased appetite, vomiting and constipation, in two placebo-controlled trials in adults with type 2 diabetes (US label).

Side effect	14 mg	7 mg	Placebo
Nausea	20%	11%	6%
Abdominal pain	11%	10%	4%
Diarrhoea	10%	9%	4%
Decreased appetite	9%	6%	1%
Vomiting	8%	6%	3%
Constipation	5%	6%	2%

US label, pool of two placebo-controlled trials in type 2 diabetes (US label).

Most of the nausea, vomiting and diarrhoea came while the dose was being raised. 8% of people on 14 mg and 4% on 7 mg stopped because of stomach and gut side effects, against 1% on placebo. In rodents, semaglutide causes thyroid C-cell tumours; the label's boxed warning says it is unknown whether the tablets cause them in humans, and the tablets are contraindicated in people with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2 (US label). These are figures from diabetes trials; whether the tablet suits someone for weight, off-label, is the doctor's decision.

How do the tablets compare with injections for weight loss?

The tablet registered here was studied for blood sugar, and the weight change in its trials was smaller than in the weight-management injection trials. They are separate trials, of different lengths and in different people, so this is a gap between trial results, not a head-to-head result.

• The registered tablet, 14 mg: in a 26-week trial in its US label, adults with type 2 diabetes taking it alone changed weight by −3.7 kg on average, against −1.4 kg on placebo, from a starting weight of about 88 kg (US label).
• The weight-management injections registered here: in STEP 1, adults without diabetes on semaglutide 2.4 mg changed weight by −15.3 kg (−14.9%) over 68 weeks, against −2.6 kg on placebo (Wilding 2021); in SURMOUNT-1, tirzepatide 15 mg gave −20.9% over 72 weeks, against −3.1% (Jastreboff 2022).
• Tablets at weight-management doses, approved abroad and not registered here: −13.6% at 64 weeks on the 25 mg semaglutide tablet in OASIS 4 (Wharton 2025), and −11.2% at 72 weeks on the highest orforglipron dose in ATTAIN-1 (Wharton 2025), both in adults without diabetes.

Individual results vary and are not guaranteed. How the newer tablets and injections compare sets these trials side by side. Foundayo vs Wegovy pill: which works better? compares the two tablets approved abroad.

So what are the options here?

By registration, injections: the GLP-1 medicines registered in Singapore for weight management are given by injection — the register lists the routes (HSA register), and the one oral product among them carries a diabetes indication (Singapore product information). The tablet can be prescribed for weight off-label, and whether it suits you is a decision for the doctor who assesses you.

Whether GLP-1 medication of any kind is appropriate for you is a separate question again, decided at an assessment rather than by a registration document. Other approaches to weight management exist and are compared in every weight-loss option in Singapore. How the rules work locally is in GLP-1 medication in Singapore: the legal position.

Where this leaves compounded or imported "oral GLP-1"

Somewhere worth being blunt about, because the gap this article describes is exactly the gap grey-market sellers advertise into.

If the registered oral product here is for diabetes, and the overseas weight-management approval does not apply here, then an oral GLP-1 weight-loss product sold direct to a Singapore consumer, with no prescription behind it, is not a registered Singapore option. It may be an imported product outside our regulatory system, a compounded preparation, or something that is not what it claims to be at all.

What any particular seller is actually offering is not something we can see. What can be said is that "there is an oral version" and "there is an oral version registered here for weight" are different statements, and only the first is true. The legal position on GLP-1 medication in Singapore and grey-market GLP-1 cover how to tell a licensed supply route from an unlicensed one.

What does HSA say about slimming pills sold online?

HSA warns that the claims made for weight-loss products sold online are often "exaggerated or unsubstantiated by any scientific evidence and impossible to verify", that buyers cannot be sure what the products contain, and that some are sold with undeclared potent medicinal ingredients (HSA). In the cases it names, products labelled natural were found by HSA's analysis and testing to contain sibutramine, a former prescription weight-loss medicine disallowed for sale in Singapore since 2010 because of an increased risk of heart attacks and strokes, as well as a laxative and an undeclared painkiller. In January 2024 HSA found high amounts of sibutramine in three more products marketed online as natural or herbal and sold on a local e-commerce platform (HSA, January 2024).

HSA's advice is to be wary of products that claim to be "100% herbal", "100% natural" or "clinically proven", or that promise weight loss within days, and not to buy products from unknown or unverifiable sources (HSA, January 2024). GLP-1 medicines, by contrast, are prescription-only, and HSA says they should only be used under the supervision of a doctor who assesses whether they are appropriate (HSA 2026).

What is the strongest weight loss pill over the counter?

The only weight-management medicine on Singapore's register available without a prescription is orlistat 120 mg: it is classified Pharmacy Only rather than Prescription Only, so it is supplied by or under the supervision of a pharmacist (HSA register). In its four-year trial, XENDOS, adults on orlistat lost 5.8 kg on average against 3.0 kg on placebo (Torgerson 2004); individual results vary. Phentermine, naltrexone-bupropion and every GLP-1 medicine on the register, the GLP-1 tablet included, are Prescription Only (HSA register).

Orlistat, phentermine and GLP-1 sets the older medicines' trials beside the GLP-1 ones. GetLean does prescribe and supply HSA-registered GLP-1 medications, after a consultation with Dr Quek. A consultation does not guarantee a prescription.

If injecting is the obstacle

Then the other useful thing to know is that the obstacle itself is more movable than the registration is.

Fear of needles is common, and much commoner than people assume when they are the one feeling it. Afraid of needles covers how common it really is, what has been tried, and how thin the evidence for those things actually is. Your first GLP-1 injection covers what the trials recorded, which is a lower reaction rate than most people expect.

Neither of those pages promises the fear will go away. What they do is replace a vague dread with specific information, which is a reasonable place to start.

And if you cannot face it, say so at the consultation rather than deciding alone that you are not a candidate. It is a clinical conversation, and it is one doctors have regularly. You can book your consult and speak to a doctor about whether this is suitable for you.

The registered strengths of the oral product, and the doses its obesity trials actually used, are set out in the tablet, and what it is for. A second oral GLP-1 — a different class of molecule entirely, needing no absorption workaround — is approved overseas and covered in what is actually coming. A semaglutide tablet for weight management, the Wegovy pill, is also approved abroad and is not registered in Singapore.

What happens when you stop taking a GLP-1 tablet (oral semaglutide)?

It fades over weeks, like the injection. The tablet registered in Singapore is for type 2 diabetes, so stopping or changing it is the prescribing doctor's decision; the weight figures usually quoted come from injection trials, not tablets. At GetLean the programme is designed to get you off GLP-1, where clinically appropriate: the dose is stepped down at Dr Quek's monthly reviews rather than stopped overnight, towards the lowest effective dose; daily WhatsApp coaching builds the habits. We call it the GetLean GLP-1 Taper Plan. Individual results vary. Never stop or change a prescribed medicine on your own. Coming off a GLP-1 tablet: what is known and what is not has the detail.

Common questions

Is there a GLP-1 tablet in Singapore?

Yes. An oral form of one GLP-1 medicine is registered here in three tablet strengths (HSA register). Its registered indication is type 2 diabetes, not weight management (Singapore product information).

Can I take the tablet for weight loss instead?

It can be. The tablet registered in Singapore is for type 2 diabetes, so using it for weight is off-label, and whether it suits you is Dr Quek's decision at your consultation. Some people prefer it because there is no injection. A consultation does not guarantee a prescription.

I read that there is an oral weight-loss GLP-1. Was that wrong?

It was probably right about somewhere else. The current United States labelling does include an oral tablet presentation alongside the injection (US prescribing information). That approval has no standing in Singapore, where the registered oral product carries a type 2 diabetes indication (Singapore product information).

So for weight management, the options here are injections?

Not only. The GLP-1 medicines registered here for weight management are given by injection — the register lists the routes (HSA register), and the one oral product among them carries a type 2 diabetes indication (Singapore product information). The tablet can be prescribed for weight off-label, and whether it suits you is a decision for the doctor who assesses you.

What if I genuinely cannot face injecting?

Say so at the consultation rather than ruling yourself out. Needle fear is common, and it is a clinical conversation rather than a disqualification.

What are the side effects of the GLP-1 tablet?

In the US label's trials in adults with type 2 diabetes, the most common were nausea (20% on 14 mg against 6% on placebo), abdominal pain, diarrhoea, decreased appetite, vomiting and constipation, mostly while the dose was being raised; 8% on 14 mg stopped because of stomach and gut side effects, against 1% on placebo (US label).

What does HSA say about slimming pills sold online?

HSA says their claims are often exaggerated or impossible to verify, and it has named products sold online as natural that were found to contain sibutramine, a substance disallowed in Singapore since 2010 (HSA; HSA, January 2024). GLP-1 medicines are prescription-only and are used under a doctor's supervision (HSA 2026).

Which pill is best for weight loss?

No head-to-head weight-loss trial of the GLP-1 pills was found, so none can be called the best. In Singapore the only GLP-1 pill registered is oral semaglutide (Rybelsus), for type 2 diabetes only, so using it for weight is off-label (HSA register; Singapore product information). The weight-management pills approved abroad were each tested against placebo: −13.6% at 64 weeks on the 25 mg semaglutide tablet and −11.2% at 72 weeks on the highest orforglipron dose (Wharton 2025; Wharton 2025). Which medicine suits a person, if any, is decided by the doctor who assesses them. Individual results vary and are not guaranteed.

Are GLP-1 pills available in Singapore?

One is: oral semaglutide, sold as Rybelsus, at 3, 7 and 14 mg, registered for type 2 diabetes only, so prescribing it for weight is off-label (HSA register; Singapore product information). The weight-management pills approved abroad, the 25 mg semaglutide tablet and orforglipron, are not registered here (HSA register).

Is tirzepatide a pill?

No. Tirzepatide is a once-weekly injection under the skin, and every tirzepatide product on Singapore's register is an injection (Jastreboff 2022; HSA register).

Can I buy slimming pills over the counter?

Not GLP-1 pills: GLP-1 medicines are prescription-only in Singapore, used under the supervision of a doctor (HSA 2026). For other slimming products sold online, HSA warns that their claims are often exaggerated or impossible to verify, that some have been found to contain undeclared medicines such as sibutramine, and that people should avoid products from unknown or unverifiable sources (HSA; HSA, January 2024).

What is the strongest weight loss pill over the counter?

The only weight-management medicine on Singapore's register available without a prescription is orlistat 120 mg: it is classified Pharmacy Only rather than Prescription Only, so it is supplied by or under the supervision of a pharmacist (HSA register). In its four-year trial, XENDOS, adults on orlistat lost 5.8 kg on average against 3.0 kg on placebo (Torgerson 2004); individual results vary. Phentermine, naltrexone-bupropion and every GLP-1 medicine on the register, the GLP-1 tablet included, are Prescription Only (HSA register).

Who should not take Rybelsus?

Singapore's product information says the tablet must not be used by anyone hypersensitive to semaglutide or to any of its ingredients (Singapore product information), and the US label adds people with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2 (US label). Whether it suits someone is decided by the doctor who assesses them.
