I would not expect a doctor to know what benfotiamine is.
When faced with this type of dilemma just say...it is an improved form of Thiamine B1. Thiamine has been a treatment for PN for many decades. Perhaps the doctor's response would change with that detail added. (you can amend the list she has to reflect that, so she doesn't forget).
Most doctors do not even know which number goes with each B in Bcomplex! I've run into pharmacists who also fail at this task.
