Warfarin/Coumadin Patient Support

Why we work so hard to support our patients on Warfarin/Coumadin


Warfarin (Coumadin) is a medication that is prescribed for patients that have blood clots or heart conditions that can lead to blood clots. Warfarin can be a dangerous drug if it is not properly managed by a healthcare professional shown by the high number of Emergency Room visits for side effects each year. The Peninsula Community Health Services pharmacists have been working with patients on warfarin for over 7 years to ensure that our they are safely managed to prevent blood clots and side effects. Nationally, about 50% of warfarin patients are in the goal range when they are followed by a healthcare professional. Our pharmacists’ dedication to providing a high level of care is shown by our patient’s being 20-30% above this national average with a very low rate of side effects and hospital visits caused by warfarin.
