RT Journal Article SR Electronic T1 Possible interaction between pomegranate juice and warfarin JF Emergency Medicine Journal JO Emerg Med J FD BMJ Publishing Group Ltd and the British Association for Accident & Emergency Medicine SP 74 OP 75 DO 10.1136/emj.2007.055855 VO 27 IS 1 A1 S Jarvis A1 C Li A1 R G Bogle YR 2010 UL http://emj.bmj.com/content/27/1/74.abstract AB Pomegranate juice is growing in popularity in the UK. We report a potential interaction between pomegranate juice and warfarin. Laboratory studies have shown that pomegranate juice inhibits cytochrome P450 enzymes involved in warfarin metabolism. As with previous reports of interactions between food and warfarin, this case does not definitively prove the association between pomegranate juice consumption and increased warfarin bioactivity but highlights the importance of taking a complete drug, food and juice history when assessing patients with unstable anticoagulation.
