Side effects of Quizartinib

Quizartinib may cause a variety of side effects during treatment, posing a challenge to the patient's health.

Bone marrow suppression

Quizartinib may cause bone marrow suppression, leading to thrombocytopenia, neutropenia, anemia and leukopenia. These side effects may increase the risk of infection and bleeding, and regular blood routine tests are required.

Nausea, vomiting and diarrhea

Gastrointestinal symptoms are one of the common side effects of Quizartinib, including nausea, vomiting and diarrhea. These symptoms may cause patients to lose their appetite and poor nutrient absorption, which in turn affects their overall health.

Side effect mitigation measures of Quizartinib

A series of mitigation measures can be taken for the side effects of Quizartinib to improve the patient's tolerance and quality of life.

ECG monitoring and electrolyte correction

To prevent arrhythmias caused by QT interval prolongation, patients should undergo regular ECG examinations before and during the use of Quizartinib, and monitor electrolyte levels such as potassium and magnesium, and perform electrolyte correction when necessary.

Blood transfusion and growth factor therapy

For hematopoiesis caused by bone marrow suppression, blood transfusion, growth factor therapy and other measures can be taken according to the specific situation to maintain the number of blood cells within the normal range.

Drug treatment and dietary adjustment

For digestive tract symptoms, antiemetics, antidiarrheal drugs and other drugs can be used for symptomatic treatment, adjust the diet structure, choose light and easily digestible food, and avoid increasing the gastrointestinal burden.
