I am sorry about your Mom. Losing a loved one is never easy.
However, Coumadin is a drug that has been around for a long time. It is prescribed for blood clots. If Coumadin has a synergistic action with Tylenol, I am not aware-- Tylenol in excessive doses is toxic to the liver. Consumers need to understand that there is not a drug--including aspirin, that does not have side effects. It is up to the patient/consumer to be informed. If the doctor was not regularly monitoring her clotting and bleeding time, he was the one that was negligent--not the drug company.
My condolences on your loss...
This is exactly the kind of thing I was talking about. Why should doctors or the government have all the information and make all the decisions for us? We are literate adults. And all of us here in FreeRepublic can use the internet. If the FDA kept all the data for those drugs online, you could have looked up the side effects and not had to rely on the "experts". You could have raised the BS flag. Or accepted the risk knowingly.
