Consumer information for this interaction is not currently available.
GENERALLY AVOID: Coadministration with moderate inhibitors of CYP450 3A4 may increase the plasma concentrations of venetoclax, which is a substrate of the isoenzyme. In 11 previously treated non-Hodgkin's lymphoma patients, venetoclax peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 2.3- and 6.4-fold, respectively, when coadministered with 400 mg once daily for 7 days of ketoconazole, a potent CYP450 3A4 inhibitor that also inhibits P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP). Increased venetoclax exposure may potentiate the risk of tumor lysis syndrome, particularly at initiation of therapy and during the dosage ramp-up phase, as well as other adverse effects such as diarrhea, nausea, vomiting, neutropenia, anemia, and thrombocytopenia.
MANAGEMENT: Concomitant use of venetoclax with moderate CYP450 3A4 inhibitors should generally be avoided. If coadministration is required, the manufacturer recommends that venetoclax dosage be reduced by at least 50%. The dosage used prior to initiating the CYP450 3A4 inhibitor may be resumed 2 to 3 days after discontinuation of the inhibitor.

Drug and food interactions
venetoclax food
Applies to: venetoclax
Food helps to increase the absorption of venetoclax. You should take each dose of venetoclax with a meal and water at approximately the same time each day. Do not consume grapefruit, grapefruit juice, Seville oranges, or starfruit during treatment with venetoclax. Doing so can significantly increase blood levels and effects of the medication. This may increase your risk of developing tumor lysis syndrome, a serious condition that is caused by the rapid breakdown of cancer cells and that can lead to kidney failure and even death. In addition, you may be more likely to experience other side effects such as nausea; vomiting; diarrhea; fatigue; and impaired bone marrow function resulting in low numbers of different types of blood cells, which can increase the risk of anemia, bleeding problems, and infections. Talk to your doctor if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
