What is the most important information I should know about mobocertinib?

Call your doctor at once if you have fast or pounding heartbeats, fluttering in your chest, shortness of breath, and sudden dizziness (like you might pass out).

What is mobocertinib?

Mobocertinib is used in adults to treat non-small cell lung cancer that has spread to other parts of the body (metastatic) and cannot be removed with surgery, and whose disease has worsened while on or after chemotherapy with platinum.

Mobocertinib is used if your cancer has a specific genetic marker (an abnormal "EGFR" gene). Your doctor will test you for this gene.

Mobocertinib may also be used for purposes not listed in this medication guide.

What should I discuss with my healthcare provider before taking mobocertinib?

Tell your doctor if you have:

  • heart problems, including long QT syndrome;
  • an electrolyte imbalance (such as low blood levels of sodium, potassium, calcium, or magnesium); or
  • lung or breathing problems other than lung cancer.

You may need to have a negative pregnancy test before starting this treatment.

Both men and women using this medicine should use effective birth control to prevent pregnancy. Mobocertinib can harm an unborn baby if the mother or father is using this medicine.

Keep using birth control for at least 1 month for women and at least 1 week for men after your last dose. Tell your doctor right away if a pregnancy occurs.

Mobocertinib can make birth control pills less effective. Ask your doctor about other birth control options such as an injection, implant, skin patch, vaginal ring, condom, diaphragm, cervical cap, or contraceptive sponge.

Do not breastfeed while using this medicine, and for at least 1 week after your last dose.

Mobocertinib may affect fertility in men or women. Pregnancy could be harder to achieve while either parent is using this medicine.

What happens if I miss a dose?

Use the medicine as soon as you can, but skip the missed dose if you are more than 6 hours late for the dose. Do not use two doses at one time.
