Interactions between your drugs
dabrafenib olaparib
Applies to: dabrafenib and Lynparza (olaparib)
Consumer information for this interaction is not currently available.
GENERALLY AVOID: Coadministration with potent and moderate inducers of CYP450 3A4 may significantly decrease the plasma concentrations of olaparib, which is primarily metabolized by the isoenzyme. In a drug interaction study with 22 patients, olaparib peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by approximately 71% and 87%, respectively, during coadministration with the potent CYP450 3A4 inducer rifampin. Simulations using physiologically-based pharmacokinetic (PBPK) models suggest that a moderate inducer (efavirenz) may decrease olaparib Cmax by 20% to 30% and AUC by 50% to 60%.
MANAGEMENT: Concomitant use of olaparib with potent and moderate CYP450 3A4 inducers should generally be avoided. If coadministration with a moderate CYP450 3A4 inducer such as bosentan, dexamethasone, efavirenz, etravirine, modafinil or nafcillin is required, the potential for decreased efficacy of olaparib should be considered.
Drug and food interactions
olaparib food
Applies to: Lynparza (olaparib)
Do not consume grapefruit, grapefruit juice, or Seville oranges during treatment with olaparib. Doing so can significantly increase the blood levels of olaparib and increase the risk and/or severity of side effects such as nausea, vomiting, diarrhea, indigestion, loss of appetite, abdominal pain or discomfort, lung problems, and impaired bone marrow function resulting in low numbers of different types of blood cells. You may also be more likely to develop anemia, bleeding problems, or infections due to low blood cell counts. 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.
dabrafenib food
Applies to: dabrafenib
Food may delay and reduce the absorption of dabrafenib, which may lead to lower blood levels of the medication and possibly reduced effectiveness. You should take dabrafenib at least 1 hour before or 2 hours after a meal.
