Let me deal with informing doctors. It's quite possible to know which doctors are prescribing which medications, so Health Canada wouldn't be beyond the pale. This might fall under provincial jurisdiction, so I want to be careful here. If a doctor is prescribing a fair amount of a drug that is found to be causing a lot of adverse events, those doctors could be targeted with messages. I believe that Health Canada and some private companies actually do that. How effectively they do it, I don't know.
As for information coming in the other direction, I think Mr. Ménard said it quite well. The choice for a doctor is either treating the patient or reporting the adverse event. From talking to doctors, given the work they have to do, it's very difficult for me to see how we could encourage them to report more frequently. It takes time away from their very busy practices and away from the patients, and it's not crystal clear. There is a fairly good website, if I understand correctly. There's the telephone.
One way that might be more practical would be to have the provincial agency or Health Canada, whichever has jurisdiction, contact doctors who are writing a lot of prescriptions for drugs at risk. That would be a relatively inexpensive way to do it. Ask them if they're getting adverse reactions.
