Specific Femara Warnings and PrecautionsFollowing are some warnings and precautions to be aware of prior to taking Femara:
- The liver helps clear Femara from the body. Therefore, if you have liver disease, talk with your healthcare provider before taking the drug. Depending on the severity of your condition, your healthcare provider may recommend adjusting your Femara dosage or not taking the drug at all.
- Femara (as well as most medications that decrease the effects of estrogens) can lead to osteoporosis. If you already have osteoporosis (or are at risk for the condition), your healthcare provider may recommend certain lifestyle changes or medication to protect you from fractures (see Osteoporosis Prevention).
- Femara can potentially interact with certain other medications (see Femara Drug Interactions).
- Femara is considered a pregnancy Category X medication. This means that it is likely to cause harm to a fetus during pregnancy. Talk with your healthcare provider about the risks and benefits of taking the drug while pregnant (see Femara and Pregnancy).
- It is not known if Femara passes through breast milk. Therefore, if you are breastfeeding or plan to start breastfeeding, discuss this with your healthcare provider prior to taking Femara (see Femara and Breastfeeding).
