Zanubrutinib
Summary
Zanubrutinib is used to treat certain blood cancers, including mantle cell lymphoma and chronic lymphocytic leukemia. These are types of cancer that affect the blood and lymphatic system, which is part of the immune system.
Zanubrutinib works by blocking Bruton's tyrosine kinase, which is a protein that helps cancer cells grow. By inhibiting this protein, it slows down the growth and spread of cancer cells, helping to manage the disease.
The usual starting dose of Zanubrutinib for adults is 160 mg taken twice daily. It is taken orally, which means by mouth, and can be taken with or without food. Always follow your doctor's specific dosing instructions.
Common side effects of Zanubrutinib include fatigue, which means feeling very tired, diarrhea, which is loose or watery stools, and bruising, which is when the skin becomes discolored due to bleeding underneath.
Zanubrutinib can increase the risk of infections and bleeding. It should not be used if you are allergic to it or its ingredients. People with liver problems should use it cautiously, as it may worsen liver function.
