Bringing prescription medicine into Singapore from Japan
Check before you book
Singapore’s Health Sciences Authority (HSA) describes a ceiling of three months’ supply for personal imports and says quantities above it are not permitted. Prescription length and entry allowance are separate. Ask HSA how it counts the supply for your particular dose and quantity, especially if the dose changes.
If you live in Singapore
HSA’s published criteria specify lawful prescribing in the country of residence and a valid prescription or doctor’s letter from that country. Ask HSA whether your situation meets the criteria if the medicine was prescribed and dispensed in Japan. We have no case-specific confirmation that Japanese documents alone suffice for a Singapore resident.
Check the exact active ingredient and presentation
Use HSA’s current ingredient checklist and its Document Guide. Approval requirements depend on the product and active ingredients. We have not obtained an HSA determination for your Japanese tirzepatide product. If approval is required, HSA advises applying at least two weeks before arrival. The three-month ceiling still applies.
Keep the documents and pharmacy-labelled packaging
Keep the original labelled packaging, with patient name, medicine and quantity, and carry the required prescription or letter. A Japanese English-language certificate can document your treatment but cannot establish eligibility for entry. Follow any instructions issued by HSA or border officers.
Plan safe transport
Ask the dispensing pharmacist how to transport your exact pen and keep it within the required temperature range. Check your airline’s cabin baggage and needle procedures separately. This clinic’s collection and delivery arrangements are within Japan.
