Side effects can include nausea, headache, blood clots, breast pain, depression, and liver problems.[2] Use is not recommended during pregnancy, the initial three weeks after childbirth, and in those at high risk of blood clots.[2][4] It, however, may be started immediately after a miscarriage or abortion.[4] Smoking while using combined birth control pills is not recommended.[5] It works by stopping ovulation, making the uterus not suitable for implantation, and making the mucus at the opening to the cervix thick.[4]
This combination pill was approved for medical use in the United States in 1964.[6] It is on the World Health Organization's List of Essential Medicines.[7] It is available as a generic medication.[8] It is marketed under a large number of brand names.[9] In 2022, the combination of ethinylestradiol with norethisterone or with norethisterone acetate was the 80th most commonly prescribed medication in the United States, with more than 8 million prescriptions.[10][11]
