Are semaglutide and tirzepatide approved in Singapore?
Semaglutide and tirzepatide are prescription medicines in most countries, and Health Sciences Authority (HSA) is the authority that decides which products may be sold in Singapore, under which brand names and for which uses.
Approval in another country does not make a product legal in Singapore. If you are unsure whether a product you have been offered is authorised, check with Health Sciences Authority (HSA) or ask a licensed pharmacist.
Who can prescribe weight loss medicines in Singapore
A licensed medical professional should assess your health before prescribing either medicine. If a clinic or website in Singapore offers to supply them without a consultation, treat that as a warning sign whatever the local rules say.
Ask for the full name and registration details of the prescriber and confirm them with the professional council or health authority in Singapore.
Advertising and online offers
Most countries, apart from the United States and New Zealand, restrict advertising of prescription medicines to the public. Whatever the local rules in Singapore, an advert or social media post is not a medical assessment, and offers that skip a consultation are a warning sign.
Fake and unlicensed products
The World Health Organization has issued alerts about falsified semaglutide pens found in several regions. Falsified products may contain the wrong ingredient, the wrong amount or something harmful, and can look very similar to the real packaging.
Safer habits: get the medicine from a licensed pharmacy with a prescription, check the packaging and batch details, never buy from a social media seller, and report suspected fakes to Health Sciences Authority (HSA).
Botox, fillers and medical aesthetics in Singapore
Botulinum toxin products are prescription medicines in most countries, and Health Sciences Authority (HSA) decides which brands are authorised in Singapore. Dermal fillers are usually regulated as medical devices.
Ask who will treat you, what their medical registration is, which product brand will be used and how the clinic handles complications such as a blocked blood vessel.
What a safe weight loss program looks like
- A real consultation with a named, registered prescriber who reviews your health history and current medicines.
- Clear information on which exact product you would receive, and whether it is a brand-name medicine or a compounded preparation.
- A licensed pharmacy as the supplier, with packaging you can check.
- A follow-up plan for side effects, dose changes and what happens when you stop.
- Nutrition and activity support, not just a prescription.
- Registration you can confirm yourself, for example through the Singapore Medical Council.

Frequently asked questions
Do I need a prescription for semaglutide or tirzepatide in Singapore?
These are prescription medicines in most countries. Health Sciences Authority (HSA) sets the rules in Singapore, and a legitimate supplier will ask for a prescription or arrange a consultation first.
Is it safe to buy weight loss injections online in Singapore?
Only from a licensed pharmacy with a valid prescription. Falsified semaglutide pens have been found by regulators, and sellers on social media or websites that skip the prescription are the most common source of them.
What is the difference between semaglutide and tirzepatide?
Semaglutide acts on the GLP-1 hormone receptor. Tirzepatide acts on two receptors, GIP and GLP-1. Both are weekly injections that affect appetite and blood sugar, and a prescriber decides which, if either, is suitable for you.
Can a medical spa in Singapore offer GLP-1 weight loss?
Some medical spas and aesthetic clinics run weight management programs with a licensed prescriber. Whether that is allowed, and who must be involved, depends on the rules in Singapore. Ask who prescribes and who follows you up.
Who regulates Botox and fillers in Singapore?
Health Sciences Authority (HSA) oversees medicines and medical products in Singapore. Professional councils decide which practitioners may inject, so check both the product and the practitioner.
