Brevicon Dosage: An Introduction
It is very important to follow dosing instructions for Brevicon®
(norethindrone/ethinyl estradiol) very carefully. Although birth control pills
are very effective at preventing pregnancy when taken as directed, their effectiveness decreases significantly if you take them incorrectly. As always, do not adjust your Brevicon dose unless your healthcare provider specifically instructs you to do so.
When you take Brevicon for the first time, you can start it two different ways:
- Sunday start -- Start Brevicon on the first Sunday after your period starts, even if you are still having your period. For many women, starting on Sunday may decrease the chance that you will have your period on the weekends (although not all women find this to be the case). You will need to use a backup method of birth control for the first seven days of the first pack, as you did not start Brevicon at the beginning of your cycle.
- Day 1 start -- Start Brevicon on the first day of your period, within 24 hours of the start of menstrual bleeding. Because you will be protected from pregnancy from the start of your cycle, no backup birth control is needed. If your period happens to start on a Sunday, treat this as a day 1 start (not as a Sunday start).
If you choose a Sunday start, you will start every pack of Brevicon on Sundays. If you choose a day 1 start, you will start each pack on your initial start day (for instance, if you first started Brevicon on a Friday, you will start every pack on a Friday).
Some healthcare providers may suggest other ways to start Brevicon (such as starting in the middle of the cycle). Make sure to follow your healthcare provider's instructions in such situations.
