What are the side effects of EVISTA?
Serious and life-threatening side effects can occur while taking EVISTA. Increased risk of blood clots in the legs (deep vein thrombosis) and lungs (pulmonary embolism) have been reported with EVISTA. Women who have or have had blood clots in the legs, lungs, or eyes should not take EVISTA. Women who have had a heart attack or are at risk for a heart attack may have an increased risk of dying from stroke when taking EVISTA.
The most common side effects are hot flashes, leg cramps, swelling, flu-like symptoms, joint pain, and sweating. Hot flashes are more common during the first 6 months after starting treatment. In clinical trials, side effects were usually mild enough that most women did not stop taking EVISTA.
These are not all the side effects of EVISTA. Tell your healthcare professional about any side effect that bothers you or that does not go away. If you have any problems or questions that concern you while taking EVISTA, ask your healthcare professional or pharmacist for more information.

Can EVISTA reduce my risk of invasive breast cancer?
If you have postmenopausal osteoporosis, EVISTA can be used to lower your chance of getting invasive breast cancer. If you do not have osteoporosis, but are past menopause and at high risk for invasive breast cancer, EVISTA may also be used to lower your risk of getting invasive breast cancer. EVISTA will not completely get rid of your chance of getting invasive breast cancer. Your doctor can estimate the risk of invasive breast cancer by assessing your personal risk factors. You and your doctor should talk about whether the possible benefit of EVISTA in lowering your chance of getting invasive breast cancer is greater than its possible risks.
Note: If you already have or have had breast cancer, EVISTA does not treat it or prevent its return, and it does not reduce the risk of all forms of breast cancer.
