Venclaxta 100 Venetoclax Posaconazole
MajorPosaconazole is a strong CYP3A inhibitor. It should not be taken together with Venetoclax when you are starting Venetoclax or while the dose is being slowly stepped up. In this period the combination raises the risk of tumor lysis syndrome (TLS), a serious problem that happens when cancer cells break down too quickly. Do not take Venetoclax and posaconazole together during this phase. Your doctor should decide which medicines are safe for you.
These medicines can affect each other in a serious way. Do not start taking them together unless your doctor has said it is OK. If you already take both, do not stop either one on your own: speak to your doctor or pharmacist soon.
