YAZ is a low-dose birth control pill that is 99% effective at preventing pregnancy when taken as directed. YAZ is the only Pill with a 24/4-day dosing schedule (you take active pills for 24 days, followed by inactive pills for four days) and the unique progestin drsp or drospirenone.

Women taking combination birth control pills, such as YAZ, may experience side effects that include nausea and vomiting, headaches, irregular bleeding, weight gain or loss due to a change in eating habits, and breast tenderness. But if side effects occur, they are generally mild and go away within the first months of use. One side effect of the Pill continues to be an increased risk of cardiovascular disease. This risk is particularly high for women who smoke and are over 35 years of age. Also, birth control pills do not protect against HIV (AIDS) or other sexually transmitted diseases (STDs).
