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] However, it may be started immediately after a miscarriage or abortion.[4] Smoking while using combined birth control pills is not recommended.[1] It works by stopping ovulation, making the mucus at the opening to the cervix thick, and making the uterus not suitable for implantation.[1]
Ethinylestradiol/levonorgestrel has been approved for medical use in the United States at least since 1982.[1] It is on the World Health Organization's List of Essential Medicines.[5] It is available as a generic medication.[6] It is marketed under a large number of brand names.[1] In 2020, it was the 159th most commonly prescribed medication in the United States, with more than 3 million prescriptions.[7][8]
