Beconase spray.
I was put onto this stuff many years ago, by a very enlightened doctor at my university, when it (or rather, other brand-names containing the same active ingredient, beclamethasone) was a prescription-only asthma medication. You had to get a special adapter so you could spray it up your nose, rather than breath it into your lungs. AND, after I left the university, it was dificult to find a doctor that would 'pretend' that you were an asthmatic, and prescribe this stuff for you, or a doctor that you could make believe you were an asthmatic.
Works pretty well as a hay-fever preventative. No side effects.
Anyway, about ten years ago, the TGA made this an over-the-counter chemist medication for hay fever. The brand I use is "Beconase" - there may be others.
This is the only case that I know of when the TGA has actually lightened up, and made the world a better place, by reducing the restriction on medication.
