Important Information about TASIGNA

TASIGNA (nilotinib) 200-mg capsules is indicated for the treatment of chronic phase and accelerated phase Philadelphia chromosome-positive (Ph+) chronic myelogenous leukemia (CML) in adult patients resistant or intolerant to prior therapy that included imatinib. The effectiveness of TASIGNA is based on hematologic and cytogenetic response rates. There are no controlled trials demonstrating a clinical benefit, such as improvement in disease-related symptoms or increased survival.

You may lower your chances for having QT prolongation with TASIGNA if you:

• Take TASIGNA on an empty stomach.
  DO NOT TAKE TASIGNA WITH FOOD

Food can affect the levels of TASIGNA in your body, which can lead to serious side effects. Taking TASIGNA on an empty stomach may lower your chances of having a possibly life-threatening heart problem called QT prolongation.

QT prolongation causes an irregular heartbeat, which may lead to sudden death.

Take TASIGNA:

• At least 2 hours after eating any food, and
• After taking TASIGNA, wait at least 1 hour before eating any food
• Avoid grapefruit, grapefruit juice, and any supplement containing grapefruit extract while taking TASIGNA. Food and grapefruit products increase blood levels of TASIGNA in your body
• Avoid taking other medicines, vitamins, or herbal supplements with TASIGNA that can also cause QT prolongation

TASIGNA is a prescription medication.

TASIGNA comes in 200 mg capsules. Your doctor will prescribe 400 mg of TASIGNA to be taken twice a day for a total daily dose of 800 mg. Each dose should be taken approximately 12 hours apart.
