Import and supply of unregistered therapeutic products for patient's use

Hospitals, clinics or nursing homes need approval from us before importing unregistered therapeutic products for patients' use.

Last updated 25 May 2026

Conditions for using this special access route (SAR)

The use of unregistered therapeutic products should only be considered for life-saving therapies, where there is an unmet medical need such as in situations where a registered treatment option is absent, and the patient's health will be clinically compromised without treatment with the unregistered therapeutic product.

Note: The safety, quality and efficacy of these unregistered therapeutic products are not assessed by us, hence requesting doctors or dentists are fully responsible for the use of such products on patients.

Approval must be obtained for each consignment of the unregistered therapeutic product before it can be imported.

Eligibility

You can apply to import unregistered therapeutic products via this SAR if you are:

  • A licensed hospital, clinic or nursing home* importing the drug for use by your own doctors or dentists on patients under their care.

  • A licensed retail pharmacy acting on behalf of, and in accordance with a valid prescription issued by a registered doctor or dentist.

  • A company acting on behalf of a licensed hospital, clinic or nursing home. You are required to obtain an importer's licence and a wholesaler's licence from us prior to the import. At least one qualified pharmacist must be named as the responsible person in the import licence.

*Specified healthcare service licensee under the Healthcare Services Act 2020

You will also need to apply for the licence to import and wholesale controlled drugs or for an approval to import therapeutic products containing psychotropic substances if your unregistered therapeutic product contains a controlled drug or a psychotropic substance, respectively.
