We encourage people taking these oral contraceptives who need more to go back to their prescriber to discuss alternative contraceptive options.

Information for people taking Brevinor 1/28

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.
