Dear Sir:
Warfarin Sodium is not a toxin but rather a well established and proven
medication that is used to treat many people who require blood thinning
for a variety of reasons. Obviously, one of the complications of blood
thinners can be the potential to have bleeding not just in the brain
but anywhere in the body. The only way to prove that there was a bleed in
the brain is to have an autopsy performed. I hope this helps
Good Luck!
