A different view

摘要

It is good that pharmacists like Sue Howshall are on the alert for interactions while doing medicines use reviews(PJ,2 September,p276).However,we take a slightly different view on some of the interactions she mentions.Although the manufacturers of omeprazole recommend that patients taking warfarin should have their international normalised ratio measured if they are given warfarin,the evidence we have found suggests that any interaction is rare.Also,although some monitoring may be appropriate with large doses offish oils,we have yet to see any evidence to suggest that concurrent use needs to be avoided.
