Venetoclax — Uses, Dosage, Side Effects & Safety

Drug class: BCL-2 inhibitor; Antineoplastic agent

Overview

Venetoclax is a prescription medicine used to treat certain types of blood cancers, including chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), and in combination with other drugs for acute myeloid leukemia (AML) in adults. It works by blocking a protein called BCL-2, which helps cancer cells survive. By inhibiting this protein, venetoclax helps to trigger the death of cancer cells. Patients should know that venetoclax is usually started at a low dose and gradually increased to reduce the risk of a serious side effect called tumor lysis syndrome (TLS). Regular blood tests and close monitoring are required, especially during the first few weeks of treatment. Always take venetoclax exactly as prescribed and report any unusual symptoms to your healthcare provider.
