As you mentioned, there are two online resources. When I go to those, in fact, I don't find enough about the ones I use. There are some industry links there, where Canadian pharma generic manufacturers list the drugs that are in short supply.
I didn't see, as you alluded to, alternatives and things like that. Unfortunately, in terms of what we find out, I'll get an e-mail in the morning that this drug is not available. That's the only way I know it's not there. There is something that is not in my cart, and that's the only way I find out whether a drug is available or not.
We could feed back, but the problem is the only place I can feed back to at the moment is my pharmacist, and they have to pick up the phone in order for you to do that.
