Today’s pills have lower doses of hormones than earlier birth control pills. This has greatly lowered the risk of side effects; however, there are both benefits and risks with taking birth control pills. Benefits include having more regular and lighter periods, fewer menstrual cramps; and a lower risk for ovarian and endometrial cancer, and pelvic inflammatory disease (PID). Serious side effects include an increased chance, for some women, of developing heart disease, high blood pressure, and blood clots. Minor side effects include nausea, headaches, sore breasts, weight gain, irregular bleeding and depression. Many of these side effects go away after taking the pill for a few months. Women who smoke, are over age 35, or have a history of blood clots or breast or endometrial cancer are more at risk for dangerous side effects and may not be able to take the pill. Talk with your doctor or nurse about whether the pill is right for you.
