Ventoxen-100mg (Venetoclax) is a prescription medication used to treat certain types of blood cancers, such as chronic lymphocytic leukemia (CLL) and acute myeloid leukemia (AML). It works by inhibiting the BCL-2 protein, which helps cancer cells survive, leading to their programmed death. Ventoxen-100mg is typically used in combination with other therapies and requires careful dosage adjustments to minimize side effects like tumor lysis syndrome (TLS). Patients should take it as directed by their doctor, with food and water. Common side effects include nausea, fatigue, and low blood cell counts. Regular monitoring is essential to ensure safe and effective treatment.
