Descriptions
Lapatinib 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. It belongs to the group of medicines called antineoplastics (cancer medicines).
Lapatinib is also used together with letrozole to treat postmenopausal women 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 unwanted effects will also occur. Some of these may be serious and must be reported to your doctor.
This medicine is available only with your doctor's prescription.
This product is available in the following dosage forms:
