Estradot 75 mcg patch supply issue

What changed in 2025?

The main funded brands of oestradiol patches changed to Estradiol TDP Mylan (supplied by Viatris) and Estradot (supplied by Sandoz).

Pharmac has secured as much Estradot as the supplier can provide. However, there may be times when there is not enough Estradot for everyone who needs it.

So that the people who need Estradot can get it, we ask that you use Estradiol TDP Mylan if you can. You can ask your pharmacist to dispense the Estradiol TDP Mylan brand for you.

Decision to fund the Estradiol TDP Mylan and Estradot brands of oestradiol patches

Media release Pharmac to fund two brands of oestradiol patches from 1 December 2025

About Estradiol TDP Mylan and Estradot 

Both Estradiol TDP Mylan and Estradot have been approved by Medsafe, this means they meet international standards for quality, effectiveness, and safety. Estradiol TDP Mylan contains the same active ingredient, in the same quantities, as the Estradot brand of oestradiol patches. It is used in other countries, like the United States, as well.

Stock status

There is ample stock of TDP Mylan brand patches. The 75 mcg strength Estradot patches are currently unavailable. The 25, 50, 100 mcg strengths are not currently affected.

Estradot 75 mcg patch supply issue

We signalled when we funded the Estradot patches in 2025 that there would be times when there is not enough Estradot for everyone.

There is still a global supply issue affecting Estradot patches

Pharmac has secured as much Estradot as the supplier can provide. However, there may be times when there is not enough Estradot for everyone who needs it.

The issues we’re experiencing are part of a global shortage of oestradiol patches. Demand for oestradiol patches has increased significantly in New Zealand and internationally, and the manufacturer of Estradot has not been able to produce enough to meet this growing demand.

This is not specific to New Zealand. Shortages are being experienced in many other countries, including Australia.

The patches limit and dispensing rules remain

To help manage supply, both the Estradiol TDP Mylan and Estradot brands of oestradiol patches will continue to have a ‘2 patch per week’ limit on each strength. People will also continue to receive one month’s supply at a time from their pharmacy.

Maintaining the patch limit, and keeping monthly dispensing, will mean that more people will have access to the strength of Estradot patches they need. Changing or removing these limits would put pressure on demand, which would increase the risk of these patches not being available.

Information for pharmacists

So that there is enough stock of Estradot for the people who need it, please consider dispensing the Estradiol TDP Mylan brand for prescriptions written generically.

Information for prescribers

Please note on the prescription a person’s preferred brand of oestradiol patches.

So that there is enough stock of Estradot for the people who need it, we ask that you consider prescribing:

  • the Estradiol TDP Mylan brand of oestradiol patches for people starting treatment.
  • the Estradiol TDP Mylan brand of oestradiol patches for people who are already using it without concern.
  • the Estradot brand of oestradiol patches for people who need it.
