Drug Description


Norethindrone/Ethinyl Estradiol combination is primarily used to prevent pregnancy. It contains two hormones, a progestin (norethindrone) and an estrogen (ethinyl estradiol). 

Brevicon 28-day works by preventing ovulation, thickening cervical mucus to hinder sperm movement, and thinning the lining of the uterus to prevent implantation. It changes the lining of the uterus, making it less receptive to the implantation of a fertilized egg. 

Use and Dosage 

Brevicon 28-day comes in the form of tablet to take by mouth as directed by your doctor, usually once daily. Pick a time of day that is easy for you to remember and take your pill at the same time each day. Swallow the tablet whole with a glass of water. Chewing the tablet may affect the taste and texture, but it does not impact the effectiveness of the medication.  

Brevicon 28-day comes in a packet of 28 pills. The first 28 pills are active pills that contain hormones, and the remaining 7 pills are inactive pills (placebos) that do not contain hormones. You take one active pill at the same time every day for 28 days, followed by one inactive pill for the next 7 days. This cycle is then repeated with a new pack. 

If you miss an active pill, take it as soon as you remember, even if it means taking two pills in one day. If you miss two or more active pills in a row, use backup contraception (such as condoms) and consult the package insert or your healthcare provider for instructions on what to do.
