Before taking this medicine
Taking birth control pills can increase your risk of blood clots, stroke, or heart attack. You are even more at risk if you have high blood pressure, diabetes, high cholesterol, or if you are overweight. Your risk of stroke or blood clot is highest during your first year of taking birth control pills. Your risk is also high when you restart birth control pills after not taking them for 4 weeks or longer.
Smoking can greatly increase your risk of blood clots, stroke, or heart attack. Your risk increases the older you are and the more you smoke. You should not take combination birth control pills if you smoke and are over 35 years old.
Do not use if you are pregnant. Stop using  Kariva and tell your doctor right away if you become pregnant, or if you miss two menstrual periods in a row. If you have recently had a baby, wait at least 4 weeks before taking birth control pills.
You should not take birth control pills if you have:
untreated or uncontrolled high blood pressure;
