Moderate Drug Interaction

Consumer information for this interaction is not currently available.

MONITOR: Coadministration with olaparib may decrease the plasma concentrations and therapeutic effects of drugs that are substrates of CYP450 1A2 and/or 2B6. The proposed mechanism, based on in vitro data, is increased clearance due to olaparib-mediated induction of CYP450 1A2 and/or 2B6.

MANAGEMENT: Caution is advised if olaparib is used concomitantly with drugs that are substrates of CYP450 1A2 and/or 2B6. Pharmacologic response and serum levels should be monitored more closely whenever olaparib is added to or withdrawn from therapy with these drugs. Dosage adjustments may be required if an interaction is suspected.

Major Food Interaction

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.
