SSSI information for HRT patches

The TGA has provided information on the SSSI and PBS arrangements for estradiol transdermal patch shortages.

To help manage the shortage of estradiol-containing transdermal patches, the TGA has made a Serious Scarcity Substitution Instrument (SSSI). It starts on 19 November 2024 and allows a pharmacist to dispense an alternative brand or strength, if appropriate, without a new prescription from the prescriber.

For detailed information, visit About the shortage of transdermal HRT patches.

For more information about SSSIs see Substituting scarce medicines and Serious Scarcity Substitution Instruments (SSSIs).

The substitution has PBS subsidy arrangements, which can be found on the PBS website. Please note that some substitutable medicines can't be PBS-subsidised under the SSSI.
