This is not a complete list of Tasigna drug interactions. Ask your doctor or pharmacist for more information.

Serious side effects have been reported with Tasigna including the following:

• Low blood counts. Low blood counts are common with Tasigna. Your doctor will check your blood counts regularly during treatment with Tasigna. Symptoms of low blood counts include:
        ○  unexplained bleeding or bruising 
        ○  blood in urine or stool 
        ○  unexplained weakness
• Liver damage. Symptoms include yellow skin and eyes.
• Pancreas inflammation (pancreatitis). Symptoms include sudden stomach area pain with nausea and vomiting.
• Bleeding in the brain. Symptoms include sudden headache, changes in your eyesight, not being aware of what is going on around you and becoming unconscious.
• Tumor Lysis Syndrome (TLS). TLS is caused by a fast breakdown of cancer cells. TLS can cause you to have:
  • kidney failure and the need for dialysis treatment
  • an abnormal heart beat
  • Your doctor may do blood tests to check you for TLS.

Do not take if you have:

• low levels of potassium or magnesium in your blood
• long QTc syndrome (see below)

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. Do not take Tasigna with food.
  • at least 2 hours after eating any food, and 
  • 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 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). 

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.

Grapefruit and grapefruit juice may interact with Tasigna and lead to potentially dangerous effects. Discuss the use of grapefruit products with your doctor.

WARNING: QT PROLONGATION AND SUDDEN DEATHS

• Tasigna prolongs the QT interval. Prior to Tasigna administration and periodically, monitor for hypokalemia or hypomagnesemia and correct deficiencies. Obtain ECGs to monitor the QTc at baseline, seven days after initiation, and periodically thereafter, and follow any dose adjustments. 
• Sudden deaths have been reported in patients receiving Tasigna. Do not administer Tasigna to patients with hypokalemia, hypomagnesemia, or long QT syndrome. 
• Avoid use of concomitant drugs known to prolong the QT interval and strong CYP3A4 inhibitors. 
• Patients should avoid food 2 hours before and 1 hour after taking dose.
