What's legally available in Singapore (HSA-registered):

The Health Sciences Authority (HSA) is Singapore's drug regulator. Currently registered GLP-1 medications:

• Ozempic (semaglutide injection) — HSA-registered for T2D. Available at clinics and hospitals.
• Rybelsus (oral semaglutide) — HSA-registered for T2D.
• Saxenda (liraglutide 3mg) — HSA-registered for weight management. This is actually the only GLP-1 formally approved for obesity in SG.
• Mounjaro (tirzepatide) — HSA-registered for T2D as of late 2025.
• Wegovy — NOT yet registered with HSA.
• Zepbound — NOT yet registered.

Pricing (SGD, at private clinics):

• Ozempic 1mg: SGD$420-550/month (~$315-413 USD)
• Saxenda 3mg/day: SGD$650-800/month (~$488-600 USD)
• Mounjaro 5mg: SGD$480-600/month (~$360-450 USD)
• Rybelsus 14mg/day: SGD$380-450/month (~$285-338 USD)

Private GP in Orchard Road area. Let me explain how prescribing works here:

For T2D patients: Any GP or endocrinologist can prescribe Ozempic, Mounjaro, or Rybelsus. If you're using Medisave (Singapore's compulsory medical savings scheme) or MediShield Life (national insurance), diabetes medications including GLP-1s can be claimed under the Chronic Disease Management Programme (CDMP). Medisave withdrawal limit for CDMP is SGD$700/year for outpatient treatment — which doesn't cover the full cost but helps.

For weight management: Saxenda is the only HSA-approved option. Most doctors prescribe Ozempic off-label for obesity, which is legal but means Medisave/MediShield won't cover it. It's entirely cash-pay or private insurance.

Private insurance coverage: Some international health plans (Cigna Global, Bupa Global, AXA) cover GLP-1s if prescribed for a medical indication. Local plans (Great Eastern, NTUC Income, AIA Singapore) generally don't cover weight management medications.

Important legal points that catch expats and tourists off guard:

Personal importation: Under the HSA's Poisons Act and Health Products Act, bringing medication into Singapore requires either:

• A valid Singapore-issued prescription, OR
• An HSA import permit (Traveller's Exemption) for up to 3 months' supply of medications prescribed overseas

You MUST declare medications at customs. Singapore takes this seriously — undeclared controlled or prescription medications can result in fines up to SGD$10,000 and/or imprisonment. GLP-1 injectables are prescription-only medicines under the Poisons Act.

Research peptides: Absolutely illegal to purchase, possess, or use in Singapore without HSA authorization. There is no "research use" exemption for individuals. Importing peptides from Chinese or US suppliers will result in seizure at customs and potential prosecution. I've seen HSA enforcement actions on this — they monitor postal packages.

Compounded medications: Singapore does not have a US-style compounding pharmacy framework. Compounded semaglutide is not legally available. Any "compounding pharmacy" advertising GLP-1s in Singapore is operating illegally.

Here's the open secret that many Singapore residents use: crossing to Johor Bahru (Malaysia) for medications. JB is literally across the causeway — 30 minutes from Woodlands.

Malaysian pricing for GLP-1s is significantly lower:

• Ozempic 1mg at KPJ Johor Specialist Hospital: RM850 (~SGD$255, ~$191 USD)
• Ozempic at a private pharmacy in JB city centre: RM650-750 (~SGD$195-225)

That's about 50% of Singapore pricing. You need a Malaysian doctor's prescription, which you can get at KPJ or other private hospitals for RM100-150 consultation fee.

Legal to bring back to Singapore? Yes, under the Traveller's Exemption, you can bring back up to 3 months' supply for personal use. Declare it at customs and keep the prescription.

Many Singaporeans make a "medical shopping trip" to JB monthly. Combine it with groceries and petrol and the savings add up.
