What should I discuss with my healthcare provider before taking toremifene (Fareston)?

You should not use toremifene if you are allergic to it, or if you have:

• an uncontrolled electrolyte imbalance (low levels of potassium or magnesium in your blood).

To make sure you can safely take toremifene, tell your doctor if you have any of these other conditions:

• endometrial hyperplasia (overgrowth of cells lining the uterus);
• bone cancer; or
• if you have ever had a blood clot.

FDA pregnancy category D. Do not use toremifene if you are pregnant. It could harm the unborn baby. Use effective birth control if you are not past menopause, and tell your doctor if you become pregnant during treatment.

It is not known whether toremifene passes into breast milk or if it could harm a nursing baby. You should not breast-feed while you are using toremifene.
