Hi, I'm a UK tech, have been for about 7 months now so still relatively new to it. We have a handful of patients on letrozole but each one wants a different brand and won't have any other. It can't be that they just don't like other brands e.g. Sandoz Amlodipine over Almus, since they all share the
