Looking for information about Brevinor 28?
Brevinor 28 is a different oral contraceptive from Brevinor 1/28. It has a lower progestogen strength. Brevinor 28 is an alternative to Norimin.
Pfizer has advised PHARMAC that stock of Brevinor 1/28 has run out. They are not expecting more stock to arrive in New Zealand until mid-February 2021.
Pfizer has been unable to source an alternative brand that is chemically equivalent.
There are on-going global constraints on all ethinyloestradiol and norethisterone products. We have previously seen the impact of this with Norimin.
We recognise this supply situation may be disruptive for some people and we apologise for this. We will continue to update this web page as information becomes available.
We encourage people taking these oral contraceptives who need more to go back to their prescriber to discuss alternative contraceptive options.
If you are currently taking Brevinor 1/28 and you need a new prescription, you will need to talk to your prescriber about what alternative contraceptive options that are best for you.
We recognise this may be disruptive for some people and we thank you for your understanding.
Several alternative funded contraceptives are listed on the Pharmaceutical Schedule including other oral contraceptives, barrier and long acting reversible contraceptives.
Your health professional will provide you with advice on the alternative types of contraception that are available, including discussing with you:
- what alternative form of contraception would work best for you
- how to maintain effective contraception when switching between brands or types of contraception
- the 7-day rule when switching between brands
