What is Lynparza?
Lynparza (olaparib) is a cancer medicine that interferes with the growth and spread of cancer cells in the body.
Lynparza is used to treat advanced ovarian cancer in women with a certain abnormal inherited gene who have responded to platinum chemotherapy.
Lynparza is also used to help maintain your body's response to prior chemotherapy for ovarian cancer, fallopian tube cancer, or peritoneal cancer when the cancer has come back.
Lynparza is also used to treat HER2-negative breast cancer that has spread to other parts of the body before or after prior chemotherapy or hormonal treatment.
Lynparza affects your immune system. You may get infections more easily, even serious or fatal infections. Call your doctor if you have a fever, weakness, tiredness, trouble breathing, easy bruising or bleeding, blood in your urine or stools, or weight loss.
You will need weekly or monthly blood tests, and your cancer treatments may be delayed based on the results.
Lynparza may also cause serious lung problems. Call your doctor if you have chest pain, wheezing, trouble breathing, or a new or worsening cough.
