Schedule listing for Brevinor 1/28(external link)

Three-month dispensing

All-at-once (stat) dispensing does not currently apply to this product. People can only collect three-months' supply at a time. We will reconsider all-at-once dispensing once the stock situation is resolved.

Alternative product

Alyacen 1/35 (pharmacode 2688441) will be funded from 1 October 2024 and a brand switch fee will apply. As of 18 October 2024, it is provisionally Medsafe-approved. The section 29 flag in the Schedule will be removed for 1 December 2024. 

Alyacen 1/35 contains the same active ingredients in the same quantities as Brevinor 1/28. However, it uses the American name for norethisterone, which is norethindrone.

Expected resolution

The supplier, Pfizer, expects supply to return to normal by the end of December 2024.
