Table of contents:

Brevicon 28-day works by preventing ovulation, which is the release of an egg from the ovary during the menstrual cycle. It contains two hormones, norethindrone and ethinyl estradiol, which work together to inhibit the release of an egg.

Brevicon 28-day thickens the cervical mucus, making it more difficult for sperm to reach the uterus, and thins the lining of the uterus, making it less receptive to implantation. By combining these actions, Brevicon 28-day is highly effective at preventing pregnancy when used as directed.

Use and Dosage

Brevicon 28-day should be taken once a day at the same time each day for 28 days. The pack contains 21 active tablets and 7 inactive tablets. You should take the active tablets for 21 days, followed by the inactive tablets for 7 days.

Brevicon 28-day tablets are meant to be swallowed whole with water, not chewed. Follow the instructions provided by your healthcare provider or the instructions on the medication label to ensure that it is used effectively and safely.

If you miss a dose of Brevicon 28-day, follow the instructions provided with the pack. Generally, you should take the missed tablet as soon as you remember and then take the next tablet at the usual time. If you miss two or more tablets, you may need to use an additional form of contraception (such as condoms) for a period.
