Do not use birth control pills if you are pregnant or if you have recently had a baby.
Do not use this medication if you have any of the following conditions: a history of stroke or blood clot, circulation problems, a hormone-related cancer such as breast or uterine cancer, abnormal vaginal bleeding, liver disease or liver cancer, or a history of jaundice caused by birth control pills.
You may need to use back-up birth control, such as condoms or a spermicide, when you first start using this medication. Follow your doctor’s instructions.
Taking hormones can increase your risk of blood clots, stroke, or heart attack, especially if you smoke and are older than 35.
Some drugs can make birth control pills less effective, which may result in pregnancy. Tell your doctor about all the prescription and over-the-counter medications you use, including vitamins, minerals and herbal products. Do not start using a new medication without telling your doctor.
