Veramil Verapamil Hydrochloride Venetoclax
MajorVenetech (Venetoclax) should not be taken together with strong CYP3A inhibitors, such as itraconazole, ketoconazole, posaconazole, voriconazole, clarithromycin or ritonavir, when you first start it and while the dose is being slowly raised (the titration phase). This is contraindicated, meaning it must not be done, because it raises the risk of TLS (tumour lysis syndrome). During the same period, moderate CYP3A inhibitors, such as ciprofloxacin, diltiazem, erythromycin, fluconazole or verapamil, should be avoided. Verapamil is one of these moderate inhibitors, so it should be avoided with Venetoclax at the start and during dose titration.
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.
