US Brand Names
Lapatinib belongs to the group of medicines called antineoplastics or cancer medicines. It is used in combination with capecitabine to treat advanced or metastatic HER2-receptor positive breast cancer (breast cancer that has already spread) after other treatments have failed.
Lapatinib is also used together with letrozole to treat postmenopausal women (women who no longer make estrogen) with hormone-receptor positive and HER2-receptor positive metastatic breast cancer.
Lapatinib interferes with the growth of cancer cells, which are eventually destroyed. Since the growth of normal cells may also be affected by the medicine, other effects will also occur. Some of these may be serious and must be reported to your doctor. Other effects may not be serious but may cause concern.
Before you begin treatment with lapatinib, you and your doctor should talk about the good this medicine will do as well as the risks of using it.
This medicine is available only with your doctor's prescription.
