What is dacomitinib?

Dacomitinib is used to treat non-small cell lung cancer that has spread to other parts of the body.

Dacomitinib is given only if your tumor has a specific genetic marker (an abnormal "EGFR" gene).

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

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

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

Do not use dacomitinib if you are pregnant. It could harm the unborn baby. Use effective birth control to prevent pregnancy while you are using this medicine and for at least 17 days after your last dose.

Do not breast-feed while using this medicine, and for at least 17 days after your last dose.

Tell your doctor if you have ever had:

  • frequent diarrhea; or
  • breathing problems (other than lung cancer).

How should I take dacomitinib?

Your doctor will perform a special test to make sure you have the correct tumor type to be treated with dacomitinib.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

Take the medicine at the same time each day, with or without food.

If you vomit shortly after taking dacomitinib, do not take another dose. Wait until your next scheduled dose time to take the medicine again.

Drink plenty of liquids while you are taking dacomitinib.

Dacomitinib can cause severe diarrhea, which can be life-threatening if it leads to dehydration or infection.

If you have diarrhea while taking dacomitinib: Call your doctor right away. You may need to start taking anti-diarrhea medicine such as loperamide (Imodium) to quickly treat diarrhea.

What happens if I miss a dose?

Skip the missed dose and use your next dose at the regular time. Do not take two doses at one time.

What happens if I overdose?

What other drugs will affect dacomitinib?

  • an antacid; or
  • a stomach acid reducer (such as Tagamet, Pepcid, Zantac).
