An inferior vena cava (IVC) filter is a small cage-like medical device that can be inserted by doctors to stop dangerous blood clots from traveling to the blood vessels of the lungs. Their structure allows them to catch fragments of clots that form in the legs or pelvis before these blockages run the risk of causing a pulmonary embolism (PE). These metal filters are surgically implanted in patients who cannot tolerate blood thinners or have seen little success with those drugs.
Letrozole is a drug approved for use only in postmenopausal women with breast cancer. But there is evidence some doctors have prescribed it as a fertility treatment because it suppresses estrogen and can promote ovulation. It is marketed under the name Femara.
The manufacturer of a breast cancer drug, letrozole, has warned fertility doctors that it has been associated with birth defects, a caution prompted by reports that the drug was being used to help a woman become pregnant.
Swiss drug manufacturer Novartis sent letters to fertility doctors worldwide to reiterate a warning that the drug should not be given to women who may be pregnant.
The U.S. label on the drug already warned that it has been associated with birth defects, but doctors continued to utilize Femara for an off-label use.
