It’s important to know that women who are pregnant or planning to get pregnant should not take Lynparza. Lynparza can harm the developing fetus. It’s also important that you don’t get pregnant while taking Lynparza; if there is any chance you can become pregnant, you must use effective birth control while you’re taking Lynparza and for at least 6 months after your last dose.

Also, women who are breastfeeding or plan to breastfeed shouldn’t take Lynparza. Together, you and your doctor will decide if you should take Lynparza or breastfeed.

The most common side effects of Lynparza are:

Lynparza also may cause serious side effects, including:

  • Myelodysplastic syndrome, a bone marrow failure disorder, which means your body can no longer make enough healthy blood cells
  • Acute myeloid leukemia, a type of blood cancer

    While low red and white blood cell counts are common side effects of Lynparza, they also can be symptoms of myelodysplastic syndrome or acute myeloid leukemia. Tell your doctor right away if you have:
    • weakness
    • fever
    • blood in your urine or stool
    • extreme tiredness
    • weight loss
    • frequent infections
    • shortness of breath
    • bruising or bleeding more easily

    Your doctor will do blood tests to check your blood cell counts every month while you are being treated with Lynparza or even weekly if you have low blood cell counts that last a long time.

  • Lung inflammation: While upper respiratory infections are a common side effect of Lynparza, tell your doctor right away if you have any new or worsening symptoms of lung problems, including: shortness of breath
    • fever
    • coughing
    • wheezing
