Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog ran from 2006 to 2016 and was intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Does pomegranate interact with blood thinners?

      In this patient, it appears there was greater “blood thinning” effect when pomegranate was taken with warfarin (Coumadin), according to this report.

    First, the details.

    • A 64-year-old woman was treated with 4 mg/day of warfarin to treat deep vein thrombosis.
    • Treatment was ongoing for several months, and the international normalized ratios (INRs) were stable.
      • INRs are used to monitor the effect of anticoagulant drugs.
    • During this time, she was drinking pomegranate juice 2 to 3 times each week.
    • Then, she stopped drinking the juice, and her INRs became too low.
    • Her dosage of warfarin was increased to maintain therapeutic anticoagulation.

    The bottom line?

    For obvious reasons, there was no attempt to restart drinking the pomegranate juice due to the potential bleeding risk to the patient.

    However, Dr. Kathy Komperda from the Midwestern University Chicago College of Pharmacy, in Illinois supports her conclusion based on animal and laboratory studies that suggest a potential for pomegranate juice to inhibit metabolism of warfarin by the cytochrome P450 liver enzyme system — an effect that could translate into a clinical drug-diet interaction with warfarin.

    Yes, “This potential interaction needs to be explored further, [but] clinicians should be aware of the interaction and thoroughly interview and closely monitor their patients who are receiving warfarin.”
