My 84 year old Mother had been on Warfarin for years then was placed on Pradaxa. Five weeks latter she had two strokes in two days and now is in palliative care to die. Prior to that she had been fine.

Seems strange that a change of drug results in a stroke?

How can the Pradaxa people know a persons INR without a blood test?

I believe this drug constituted to Mam's stroke.
