Before taking Femara, tell your doctor if you have osteoporosis, high cholesterol, or liver disease (especially cirrhosis).
Femara may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert. To be sure this medicine is helping your condition, your blood may need to be tested often. Your bone mineral density may also need to be checked. Visit your doctor regularly.
Tell your doctor about all other medicines you use, especially tamoxifen (Soltamox).
You may take this medicine with or without food.
