Issues with alternate brands
We have heard that people are experiencing issues with the Mylan and Estraderm brands of patches.
Check the relevant information leaflet on the best way to apply the patch. Your pharmacist may also be able to offer more guidance.(external link)
The steps for applying the patch for Estradot are not on the consumer information sheet. They are on a separate sheet in the Estradot box. You can read the Estradot consumer information information sheet [PDF](external link) but it doesn't contain application instructions.
Pharmac has issued a Future Procurement Opportunity (FPO) for the supply of transdermal oestradiol products, that is products that deliver oestradiol through the skin. The FPO can be found on the government’s procurement site, GETS(external link)
An FPO is the first step in a procurement process.
- Media release: Pharmac indicates interest to fund more oestradiol treatments to relieve supply issue
- Future Procurement Opportunities (FPOs) at Pharmac
We hope this process will alleviate supply pressures and provide people with a greater range of oestradiol presentations. Any funding decisions would be subject to the future bids received from suppliers and available budget.
We will continue to secure supply of oestradiol patches to address this supply issue.
Who to contact
For pharmacists, please report any concerns to Medsafe(external link) about efficacy of the patches.
About this supply issue
Demand has sky-rocketed
Over the last 2 years demand has more than doubled, demand has grown from about 1 million patches in 2020 to over 2.3 million patches a year in 2022.
The increasing, rapidly shifting demand means that the supplier needs to continually amend its planning and forecasting to increase orders for delivery to New Zealand, which can take time.
Demand has increased globally
Globally, suppliers are reporting extraordinary increases in demand for oestradiol patches. As a result, they are building up their production capabilities. In addition, to this rapid increase in demand, distribution issues have also complicated supply, due to global and local supply chain disruptions caused by COVID-19.
What Pharmac is doing
Because of the ongoing global supply issues, Pharmac is:
- encouraging our supplier to review their forecasting and demand planning for the New Zealand market
- funding a range of alternative brands of the patches to ensure continuity of supply of this medication for New Zealanders
- exploring if there are other presentations or products we could secure and fund in New Zealand
- keeping Estradot stock on allocation, meaning people can only be dispensed one month of patches at a time to ensure equitable distribution of the limited stock
- where appropriate, providing support for suppliers to help speed up delivery of stock
- prioritising seeking clinical advice on which products would be appropriate for people in New Zealand seeking oestradiol treatment, and
- providing regular updates on our website so that people affected by the short supply of this treatment will have the latest information about its availability and alternatives available.
We understand that there will be people in New Zealand experiencing debilitating symptoms. We're exploring every possible option to help New Zealanders to access the medicines they need.
Thank you for your patience
We want to acknowledge the stress this supply issue might be causing some people. We recommend people contact their healthcare practitioner if they have concerns about their medicine.
Other oestradiol products
At this time we are not aware of any supply issues for oestradiol (branded as Estrofem, partially funded) or oestradiol valerate (branded as Progynova, fully funded) but it is important to note that these are different medicines so will require a new prescription and guidance from a healthcare practitioner.
