Tasigna Capsules


(nilotinib) Capsules

Read this Medication Guide before you start taking TASIGNA and each time you get a refill. There may be new information. This information does not take the place of talking to your doctor about your medical condition or treatment.

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

Tasigna can cause a possible life-threatening heart problem called QTc prolongation. QTc prolongation causes an irregular heartbeat, which may lead to sudden death.

Your doctor should check the electrical activity of your heart with a test called an electrocardiogram (ECG):

  • before starting Tasigna
  • 7 days after starting Tasigna
  • with any dose changes
  • regularly during Tasigna treatment

You may lower your chances for having QTc prolongation with Tasigna if you:

  • Take Tasigna on an empty stomach:
    • Avoid eating food for at least 2 hours before the dose is taken, and
    • Avoid eating food for at least 1 hour after the dose is taken.
  • Avoid grapefruit, grapefruit juice, and any supplement containing grapefruit extract while taking Tasigna. Food and grapefruit products increase the amount of Tasigna in your body.
  • Avoid taking other medicines or supplements with Tasigna that can also cause QTc prolongation.
  • Tasigna can interact with many medicines and supplements and increase your chance for serious and life-threatening side effects.
  • Do not take any other medicine while taking Tasigna unless your doctor tells you it is okay to do so.
  • If you cannot swallow Tasigna capsules whole, you may open the Tasigna capsule and sprinkle the contents of each capsule in 1 teaspoon of applesauce (puréed apple). Swallow the mixture right away (within 15 minutes). For more information, see “How should I take Tasigna?”

Call your doctor right away if you feel lightheaded, faint, or have an irregular heartbeat while taking Tasigna. These can be symptoms of QTc prolongation.

What is Tasigna?

Tasigna is a prescription medicine used to treat a type of leukemia called Philadelphia chromosome positive chronic myeloid leukemia (Ph+ CML) in adults who:

  • are newly diagnosed, or
  • are no longer benefiting from previous other treatments, including treatment with imatinib (Gleevec®), or
  • have taken other treatments, including imatinib (Gleevec), and cannot tolerate them

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

Who should not take Tasigna?

Do not take if you have:

  • low levels of potassium or magnesium in your blood
  • long QTc syndrome

What should I tell my doctor before starting Tasigna?

Before taking Tasigna, tell your doctor about all of your medical conditions, including if you have:

  • heart problems
  • had a stroke or other problems due to decreased blood flow to the brain
  • problems with decreased blood flow to your legs
  • irregular heartbeat
  • QTc prolongation or a family history of it
  • liver problems
  • had pancreatitis
  • low blood levels of potassium or magnesium in your blood

Tell your doctor about all the medicines you take, including prescription and nonprescription medicines, vitamins and herbal supplements.

If you need to take antacids (medicines to treat heartburn) do not take them at the same time that you take Tasigna. If you take:

  • a medicine to block the amount of acid produced in the stomach (H2 blocker): Take these medicines about 10 hours before you take Tasigna, or about 2 hours after you take Tasigna.
  • an antacid that contains aluminum hydroxide, magnesium hydroxide, and simethicone to reduce the amount of acid in the stomach: Take these medicines about 2 hours before or about 2 hours after you take Tasigna.

Tasigna can interact with many medicines and supplements and increase your chance for serious and life-threatening side effects. See “What is the most important information I should know about Tasigna?”
