Important Safety Information


LYNPARZA is a prescription medicine used to treat adults who have:

  • a certain type of abnormal inherited BRCA gene, human epidermal growth factor receptor 2 (HER2)-negative breast cancer that has spread to other parts of the body (metastatic). You should have received chemotherapy medicines, either before or after your cancer has spread. If you have hormone receptor (HR)-positive disease, you should have been treated with hormonal therapy. Your healthcare provider will perform a test to make sure that LYNPARZA is right for you

It is not known if LYNPARZA is safe and effective in children.


LYNPARZA may cause serious side effects, including:

Bone marrow problems called Myelodysplastic Syndrome (MDS) or Acute Myeloid Leukemia (AML). Some people who have ovarian cancer or breast cancer and who have received previous treatment with chemotherapy, radiotherapy, or certain other medicines for their cancer have developed MDS or AML during treatment with LYNPARZA. MDS or AML may lead to death. If you develop MDS or AML, your healthcare provider will stop treatment with LYNPARZA.

Symptoms of low blood cell counts are common during treatment with LYNPARZA, but can be a sign of serious bone marrow problems, including MDS or AML. Symptoms may include weakness, weight loss, fever, frequent infections, blood in urine or stool, shortness of breath, feeling very tired, bruising or bleeding more easily.

Your healthcare provider will do blood tests to check your blood cell counts:

  • before treatment with LYNPARZA
  • every month during treatment with LYNPARZA
  • weekly if you have low blood cell counts that last a long time. Your healthcare provider may stop treatment with LYNPARZA until your blood cell counts improve

Lung problems (pneumonitis). Tell your healthcare provider if you have any new or worsening symptoms of lung problems, including shortness of breath, fever, cough, or wheezing. Your healthcare provider may do a chest x-ray if you have any of these symptoms. Your healthcare provider may temporarily or completely stop treatment if you develop pneumonitis. Pneumonitis may lead to death.

Before taking LYNPARZA, tell your healthcare provider about all of your medical conditions, including if you:

  • have lung or breathing problems
  • have kidney problems
  • are pregnant, become pregnant, or plan to become pregnant. LYNPARZA can harm your unborn baby and may cause loss of pregnancy (miscarriage)
    • If you are able to become pregnant, your healthcare provider may do a pregnancy test before you start treatment with LYNPARZA
    • Females who are able to become pregnant should use effective birth control (contraception) during treatment with LYNPARZA and for 6 months after the last dose of LYNPARZA. Talk to your healthcare provider about birth control methods that may be right for you. Tell your healthcare provider right away if you become pregnant
    • Males with female partners who are pregnant or able to become pregnant should use effective birth control (contraception) during treatment with LYNPARZA and for 3 months after the last dose of LYNPARZA
    • Do not donate sperm during treatment with LYNPARZA and for 3 months after your final dose
  • are breastfeeding or plan to breastfeed. It is not known if LYNPARZA passes into your breast milk. Do not breastfeed during treatment with LYNPARZA and for 1 month after receiving the last dose of LYNPARZA. Talk to your healthcare provider about the best way to feed your baby during this time

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Taking LYNPARZA and certain other medicines may affect how LYNPARZA works and may cause side effects.
