Seasonale Birth Control Pills

Unlike traditional birth control pills, Seasonale® (levonorgestrel/ethinyl estradiol) is an "extended-cycle" contraceptive. This means that instead of having a monthly period, women taking it only have a menstrual period every three months (four periods per year).
As with other birth control pills, it comes in tablet form and is taken once a day. Side effects may include nausea, bleeding between periods, and headaches, among others. However, most women tolerate it well, and any side effects that occur tend to be mild and easy to treat. Before starting Seasonale, make sure your healthcare provider is aware of all your current medications. Also let him or her know if you have any medical conditions, such as diabetes, migraines, or very high blood pressure.
