To be safe, follow these guidelines
High blood pressure (180/110 mmHg or higher)
Avoid birth control pills or injections containing estrogen, which may increase your risk of a heart attack or stroke.
Episodes of depression
Avoid products that contain progestin, such as Depo-Provera, contraceptive implants, and the mini-pill. In some women with depression, progestin may worsen depressive symptoms. Also, check with your doctor if you are taking an antidepressant medication; it may affect or be affected by oral contraceptives and may require a different dose.
Seizure disorder
Avoid low-dose birth control pills. Some anti-seizure medications, such as Dilantin, accelerate liver metabolism of all substances, including oral contraceptives, and make them less effective.
Ectopic pregnancy
Avoid IUDs. Although IUDs do not cause ectopic pregnancies, if your fallopian tubes have been scarred by a previous ectopic gestation, you’re more likely to have another ectopic if you use an IUD.
Hepatitis
Avoid birth control pills or injections containing estrogen, which is metabolized in the liver—an organ damaged by hepatitis.
