Krazati side effects

Krazati can cause serious side effects, including:

Stomach and intestinal (gastrointestinal) problems. Stomach and intestinal side effects including nausea, diarrhea, or vomiting, are common with Krazati but can also sometimes be severe. Krazati can also cause serious stomach and intestinal side effects such as bleeding, obstruction, inflammation of the colon (colitis), and narrowing (stenosis).

Call your healthcare provider if you develop any of the signs or symptoms of stomach or intestinal problems listed above during treatment.

Your healthcare provider may prescribe an antidiarrheal medicine or anti-nausea medicine, or other treatment, as needed.

Changes in the electrical activity of your heart called QTc prolongation. Certain changes can occur in the electrical activity of your heart during treatment with Krazati, and can be seen on a test called an electrocardiogram (ECG or EKG). QTc prolongation can increase your risk for irregular heartbeats that can be life-threatening, such as torsades de pointes, and can lead to sudden death.

You should not take Krazati if you have congenital long QT syndrome or if you currently have QTc prolongation. See Before taking Krazati.

Your healthcare provider should monitor the electrical activity of your heart and the levels of body salts in your blood (electrolytes) during treatment if you have heart failure, a slow heart rate, abnormal levels of electrolytes in your blood, or if you take a medicine that can prolong the QT interval of your heartbeat.

Tell your healthcare provider if you feel dizzy, lightheaded, or faint, or if you get abnormal heartbeats during treatment.

Liver problems. Abnormal liver blood test results are common with Krazati and can sometimes be severe. Your healthcare provider should do blood tests before starting and during treatment to check your liver function. Tell your healthcare provider right away if you develop any signs or symptoms of liver problems, including:

your skin or the white part of your eyes turns yellow (jaundice)

nausea or vomiting

dark or "tea-colored" urine

bleeding or bruising

light-colored stools (bowel movements)

loss of appetite

tiredness or weakness

pain, aching or tenderness on the right side of your stomach area (abdomen)

Lung or breathing problems. Krazati may cause inflammation of the lungs that can lead to death. Tell your healthcare provider or get emergency medical help right away if you have new or worsening shortness of breath, cough, or fever.

The most common Krazati side effects include:

nausea

diarrhea

vomiting

tiredness

muscle and bone pain

kidney problems

swelling

breathing trouble

decreased appetite

Certain abnormal laboratory test results are common with Krazati. Your healthcare provider will monitor you for abnormal laboratory tests, and treat you if needed.

Krazati may cause fertility problems in males and females, which may affect your ability to have children. Talk to your healthcare provider if this is a concern for you.

These are not all of the possible side effects. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
