As a physician, if I prescribe a drug thinner like Warfarin, which has a clear risk of major bleeding, and I tell my patient that's the risk and we agree that he or she wants to take the risk and then the patient has a bleed, to my knowledge I don't have an obligation to report it. I have an obligation to discuss it with the patient, and I'll feel terrible that it happened, but that's a well-known side-effect of the drug. Frankly, reporting it to Health Canada, with 30 million people taking drugs, would just paralyze the system.
