Brain bleed risk from warfarin may be higher than thought

Also known as rat poison.  I  was on this for 6 months and  my ex hated having to haul me in every week to get my blood tested. Luckily I had no side effects, not even purple toe.

The widely used blood thinner warfarin -- also known as Coumadin -- may raise the risk of severe bleeding inside the skull by much more than previously thought, a new study suggests.
Researchers examined data from nearly 32,000 U.S. veterans, aged 75 and older, with a common heart rhythm disorder called atrial fibrillation. The investigators found that almost one in three suffered an "intracranial" bleed while taking warfarin for the condition.
"Atrial fibrillation ("a-fib") is a common heart rhythm disorder in elderly patients. And in patients with a-fib, treatment with the blood thinner warfarin reduces the risk of stroke by nearly two-thirds," explained study lead author Dr. John Dodson.
