Consumer information for this interaction is not currently available.

MONITOR: Coadministration with other myelosuppressive agents may potentiate and prolong the bone marrow toxicity associated with olaparib. Myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML) have been reported in patients treated with olaparib. The majority of cases were fatal, and the duration of therapy with olaparib in patients who developed secondary MDS/cancer-therapy related AML varied from less than 6 months to greater than 2 years. All patients had previous chemotherapy with platinum agents and/or other DNA-damaging agents.

MANAGEMENT: Caution is advised if olaparib is prescribed with other myelosuppressive agents. Complete blood counts should be performed at baseline and monthly thereafter. Do not start olaparib until patients have recovered from hematologic toxicity caused by previous chemotherapy. For prolonged hematologic toxicities, olaparib should be interrupted and blood counts monitored weekly until recovery. If the levels have not recovered to CTCAE Grade 1 or less after 4 weeks, a haematologist should be consulted for further investigations, including bone marrow analysis and blood sample for cytogenetics. If MDS/AML is confirmed, discontinue olaparib. Patients should be advised to contact their physician if they experience weakness, fatigue, fever, weight loss, infections, shortness of breath, unusual bleeding or bruising, or blood in urine or stool.

Drug and food interactions

Major

olaparib food

Applies to: 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.
