If it's a generic that doesn't work and the brand name works better for the patient, because it's the same molecule, the pharmacist at the base has the authority just to switch it. The policy is that they will use the generic first, but if the generic doesn't work for a specific patient, then they can go with the brand name.
If it is a change of the molecule itself.... Let's say a patient doesn't respond well to one blood pressure medication and requires a second line one. If that second line one is not listed in our benefits, then that requires a drug exception centre intervention. What they'll do is look at the patient's case specifically—it's case by case—and if the patient has looked at all the other drugs, then they can approve it in that case.
Just quickly, as well, I wanted to say that the advantage of having a very strong exception process is that when it's time to access medication.... We review medication, and it takes time for a drug to be listed on our benefit list. However, on day one, if a drug is available on the market and if a patient gets a prescription and there's a clear need, that patient could get it on day one because of the exception process we have.
