We have lots of useful information on ClotCare and have tried to organize it so that it is easy to find what you are looking for, but sometimes it seems newbies to warfarin don't know where to start. Below are some postings and frequently asked questions (FAQs) that should help you to get a broad understanding of warfarin (Coumadin) therapy. In other words, start with these postings and FAQs. :) Just click the title to go to the posting.

  1. FAQs About Warfarin (brand name Coumadin) - This posting answers some of the questions most often asked by patients new to warfarin (Coumadin). It also answers questions that many new warfarin patients simply don't know to ask.

The results of this test help your doctor to know whether you are taking too much warfarin, not enough warfarin, or just the right amount.
