To each of their own. For example, usually medicine that are marketed in the market are approved by US FDA. However there are also tons of medicine is not being approved by the US authority. So does it mean it is doubtful for doctors or pharmacy to prescribe the product? The fact that is that to each of their own(doctors and pharmacy) do indeed prescribe of product that is not approved by US FDA. On the other hand, certain prescribers is very concern that when a product/medicine is not approved by the US authority. So the question over here is that really matters when a product/medicine is not being approved by US authority but is endorse by European health authority? So to me is pretty straight fwd, there is no right or wrong. Just a matter of preference and not forgetting my pocket affordability. Just my 5cents....
