My Mother In Law is on Coumadin and detests having to be monitored so closely for adjustments to the dosage. Her Doctor told her that it is not a short term drug and that once you are on it, you have to stay on it and can not discontinue it. Check with your Dr. about that as it is possible that their opinions may vary. Here is a link to info on Wikipedia

Good luck and hope you have a good outcome
