What is Tagrisso?

Tagrisso (osimertinib) is a cancer medicine that interferes with the growth and spread of cancer cells in the body.

Tagrissois used to treat non-small cell lung cancer that is positive for an abnormal "EGFR" gene. You doctor will test you for this gene.

Tagrisso is sometimes given when the cancer has spread to other parts of the body (metastatic) or to help prevent your lung cancer from coming back after your tumor(s) has been removed by surgery.

Tagrisso is also used when your lung cancer has spread to other parts of the body and you have had previous treatment with an EGFR tyrosine kinase inhibitor medicine that did not work or is no longer working.

Warnings

Tagrisso may cause lung problems that may lead to death. Symptoms may be similar to those symptoms from lung cancer. Tell your doctor right away if you have any new or worsening lung symptoms, including trouble breathing, shortness of breath, cough, or fever.

Tagrisso may cause heart problems that may lead to death. Your doctor should check your heart function before you start taking this medicine and during treatment. Call your doctor right away if you have any of the following signs and symptoms of a heart problem: feeling like your heart is pounding or racing, shortness of breath, swelling of your ankles and feet, feeling lightheaded.

Before taking this medicine

You should not use Tagrisso if you are allergic to osimertinib.

To make sure Tagrisso is safe for you, tell your doctor if you have ever had:

  • lung or breathing problems;

  • an electrolyte imbalance (such as high or low blood levels of sodium, calcium, potassium, or magnesium);

  • eye problems; or

  • heart problems, including long QT syndrome (in you or a family member).

Osimertinib can harm an unborn baby if the mother or the father is using this medicine.

  • If you are a woman, you may need a pregnancy test to make sure you are not pregnant. Use birth control while using this medicine and for at least 6 weeks after your last dose.

  • If you are a man, use birth control if your sex partner is able to get pregnant. Keep using birth control for at least 4 months after your last dose.

  • Tell your doctor right away if a pregnancy occurs.

Pregnancy may be less likely to occur while the mother or the father is using this medicine. Both men and women should still use birth control to prevent pregnancy because the medicine can harm an unborn baby.
