Just for reference, I have a reference in my prescription drugs book: Beconase/Beclomethasone/Beclovent: "may be a disqualification for piloting".
Note this is a US publication "The Essential Guide to Prescription Drugs", 1995 edition. If it could be a problem over there, it might well be here, so best kept quiet. Also like all "cortisone-like" drugs it could have side-effects.
If still in print, this is a very useful book in that it tells you exactly which drugs pose problems with the FAA.
