You may already know this but I just found out something interesting!
I have changed pharmacies for my repeat prescription and went to the new one to explain I needed coated azathioprine.
The pharmacist said with generic tablets the doctor needs to name the makers e.g. Arrow generics, not just the tablets on the prescription to guarantee that we get the ones we need otherwise we have to take which generic ones that are in which may be coated or not.
