Effect of stress on international normalized ratio during warfarin therapy.
OBJECTIVE To discuss the effect of stress on the international normalized ratio (INR) when patients are taking warfarin. CASE SUMMARY Two patients at a pharmacist-managed anticoagulation clinic who were stable with anticoagulation developed elevated INR values after a stressful event occurred. All other factors known to elevate the INR were unchanged; furthermore, the INR values returned to t...
متن کاملWarfarin and boceprevir interaction causing subtherapeutic international normalized ratio: a case report
INTRODUCTION Chronic hepatitis C is a leading cause of severe liver disease. Protease inhibitors used to treat these patients are known to have many drug interactions, although there is limited data available between boceprevir and warfarin. This case report is the first in vivo drug interaction reported in the literature. CASE PRESENTATION A 73-year-old African American man was diagnosed wit...
متن کاملCorrelation of point-of-care International Normalized Ratio to laboratory International Normalized Ratio in hemodialysis patients taking warfarin.
BACKGROUND AND OBJECTIVES To determine whether point-of-care (POC) International Normalized Ratio (INR) test results correlate with plasma INR measures in intermittent hemodialysis (IHD) patients on warfarin. Anemia is thought to reduce the accuracy of POC INR assay results. Whether POC INR testing could be implemented for hemodialysis patients on chronic warfarin, who are often anemic despite ...
متن کاملSupratherapeutic international normalized ratio: an indicator of chronic malnutrition due to severely debilitating gastrointestinal disease
This case highlights the fact that Supratherapeutic INRs direct the attention of the treating physicians' team to the underlying severely debilitating gastrointestinal diseases. Prolonged fasting or starvation reduces vitamin K levels. Such patients are more sensitive to treatment with Vitamin K antagonist-based anticoagulants. Hence, the Supratherapeutic INR can be an objective indicator of ch...
متن کاملCardiology patient page. Warfarin management: international normalized ratio self-testing and warfarin self-dosing.
Until recently, most patients taking warfarin (brand name Coumadin) had to visit a laboratory and/or clinic every few weeks for an international normalized ratio (INR) blood test and adjustment of their warfarin dose. It is now possible for a patient to measure his/her INR (self-testing) with a finger-stick drop of blood with use of a small, portable, battery-powered device. Some self-testing p...
