GLP-1 medication is a normal prescription medicine in Singapore, regulated by the Health Sciences Authority and available through a doctor after an assessment. The parts worth understanding are narrower than "is it legal": which products are actually registered here, what the prescription-only classification obliges, and where the legal lines sit for buying, importing and supplying. This article covers each, with the primary sources attached.
Prescription Only: HSA's classification for medicines that may be supplied only against a prescription from a qualified practitioner. It is the classification carried by every registered GLP-1 product in Singapore.
What is registered here
HSA maintains a public register of every therapeutic product approved for sale in Singapore. Querying it directly for these medicines gives a clear picture (HSA register):
- Semaglutide — injectable products registered from April 2021, an oral tablet form registered from June 2021, and a further injectable family registered in February and March 2023.
- Tirzepatide — injectable products registered from March 2023.
- Liraglutide — an older GLP-1 medicine, also registered here.
Every one of these carries the classification Prescription Only.
One limitation is worth stating rather than glossing over: the public register records the product, its strengths, its licence number and its classification. It does not publish the registered indication for each product. So the register confirms what may lawfully be supplied and on what basis, but it is not the document that tells you which conditions each product is approved to treat. If that distinction matters to you — and for some people it will — it is a question for your prescribing doctor.
Note also that registration is not the same as availability. A product can be registered years before it is actually on the shelf here.
What the prescription-only classification obliges
It means a doctor decides, after assessing you, and it means nobody may lawfully supply the medicine to you without that.
The Health Products Act 2007 governs registration and supply. Supplying an unregistered health product carries a fine of up to $50,000 or imprisonment of up to two years. Supplying an adulterated, counterfeit or tampered health product carries up to $100,000 or three years (Health Products Act).
For sellers specifically, MOH stated the current position in a 2024 parliamentary reply: "The current penalties for sellers of illegal products are a fine of up to $100,000 and/or up to three years imprisonment under the Health Products Act" (MOH 2024).
A technical footnote, because the framework is often described as though it were one Act: the Health Products Act governs registration and lawful supply, while the prescription-only sale restriction sits in separate subsidiary legislation made under the Poisons Act. The practical effect for a patient is the same either way — a prescription is required.
How treatment is delivered
A doctor registered with the Singapore Medical Council assesses you and decides whether the medication is clinically appropriate. That can happen in a clinic or by video.
Telemedicine here is licensed under the Healthcare Services Act 2020, which replaced the Private Hospitals and Medical Clinics Act. Under it, telemedicine is the remote provision of an Outpatient Medical Service, governed by the Healthcare Services (OMS) Regulations 2023 and the associated licence conditions (MOH 2024).
We describe what that actually involves in what happens at a GLP-1 video consultation.
Bringing medication into Singapore
For your own prescribed medicine, HSA permits up to three months' supply without prior approval, provided you carry a valid prescription or a letter from your doctor and the medication is in its original labelled packaging (HSA).
Three conditions on that are easy to miss. It applies to medicine prescribed for you. It does not extend to bringing supplies in for friends or for resale — only immediate family for whom it was prescribed. And controlled substances are a separate category needing prior approval, with some not importable at all.
Where people actually get into trouble
Not with the clinic route. With everything that routes around it.
MOH's 2024 reply notes that in 2023, about 14% of illegal health-product listings on major local e-commerce platforms came from overseas sellers, and states plainly that "HSA does not have extra-territorial powers" — while noting HSA joined two INTERPOL-led operations and removed over 7,000 online listings (MOH 2024).
That is the practical shape of the risk. The enforcement is real, the reach over foreign sellers is limited, and the person left holding an unregistered product has no recourse if it turns out to be something other than what the label said. We cover that in grey-market GLP-1 in Singapore, which also sets out what personal import does and does not permit.
At GetLean, a doctor assesses you, decides whether treatment is appropriate, and we dispense the medication ourselves rather than routing you to a third party.

One registration detail catches people out repeatedly: an oral GLP-1 is registered in Singapore, and its indication is type 2 diabetes rather than weight management. Is there a GLP-1 that is not an injection sets out what that means for anyone hoping to avoid the needle.
Which specific products sit behind that class-level picture, and what each one's registered indication actually says, is now set out product by product: the weight-management semaglutide registration, the tirzepatide registrations.
Common questions
Is GLP-1 medication legal in Singapore?
Yes, as a prescription medicine. HSA's register classifies every registered semaglutide and tirzepatide product as Prescription Only (HSA register), meaning it is supplied on a doctor's prescription after an assessment.
Which GLP-1 medicines are registered in Singapore?
The register lists semaglutide in injectable and oral forms, registered from 2021 and 2023, tirzepatide injectables from 2023, and older liraglutide products (HSA register). The public register does not publish each product's registered indication.
Can you buy GLP-1 medication without a prescription in Singapore?
No. It is Prescription Only, and penalties for sellers of illegal health products run to a fine of up to $100,000 and/or three years' imprisonment (MOH 2024).
Can you bring GLP-1 medication into Singapore from overseas?
For your own use, up to three months' supply, with a valid prescription or doctor's letter and in original labelled packaging (HSA). Not for supply to others beyond immediate family for whom it was prescribed.
Can a doctor prescribe GLP-1 medication over video in Singapore?
Yes. Telemedicine is licensed under the Healthcare Services Act 2020 as the remote provision of an Outpatient Medical Service, under the Healthcare Services (OMS) Regulations 2023 (MOH 2024).
