All the pros and cons need to be weighed, if the blood is
too thin at present, it will further aggravate the bleeding epis
odes. It’s unfortunate that after 24 yrs, withdrawal
of Coumadin has triggered an epis
ode of stroke. Right now the progress with Coumadin has to be based on the INR status. Patients on warfarin should have an INR of 2.0 to 3.0 for basic "blood-thinning" needs. For some who have a high ris
k of clot formation, the INR needs to be higher - about 2.5 to 3.5.
