What lapatinib is
Lapatinib is also known by its brand name Tyverb. In North America it is called Tykerb. It is a treatment for advanced breast cancer.
Lapatinib may be given with the chemotherapy drug capecitabine (Xeloda) or a biological therapy called trastuzumab (Herceptin). It is also sometimes used with hormone therapies called aromatase inhibitors. Researchers are looking at using it to treat other types of cancer.
How lapatinib works
Lapatinib is a type of biological therapy called a protein tyrosine kinase inhibitor (TKI). It is a targeted treatment used for cancers that have large amounts of a protein called HER2 (human epidermal growth factor receptor 2). Some breast cancers have large amounts of HER2 and they are called HER2 positive cancers. 
HER2 makes the cancer cells grow and divide. Lapatinib switches off HER2 to make the cells stop growing or die.
How you have lapatinib
Lapatinib comes as tablets. You take them once a day with a glass of water, either an hour before or an hour after food. 
It is very important that you take tablets according to the instructions your doctor or pharmacist gives you. For example, whether you have a full or empty stomach can affect how much of a drug gets into your bloodstream. You should take the right dose, not more or less. And never stop taking a cancer drug without talking to your specialist first.
If you miss a dose, don't take an extra dose to catch up. Just take your next dose at the scheduled time.
Tests during treatment
You have blood tests before starting treatment and regularly during your treatment. The tests check your levels of blood cells and other substances in the blood. They also check how well your liver and kidneys are working.
