Percentage of American women taking birth control pills who use them, in part, for purposes other than pregnancy prevention, including reducing cramps or menstrual pain, regulating their periods, reducing acne and treating endometriosis. About 14% of pill users — or 1.5 million women — rely on the medication exclusively for non-contraceptive purposes. Among teens, the proportion is higher: girls aged 15 to 19 who use the pill are more likely to do so for non-contraceptive purposes (82%) than for birth control (67%), and 33% of teen pill users report using birth control pills solely for reasons other than contraception.
