Been through the same issue. The IAA medical examiner has become quite strict on this. I understand I passed the medical according to the mater, but the IAA were not happy. What I had to do, and what you may have to is: get your GP to refer you to a consultant respiratory (sp?) physician and have him give an opinion on whether your asthma is well controlled or not. He will examine you and you'll have to schedule a spirometry test for him to review.
Using the inhaler once a week means you should have no problem passing, you may just have an extra hoop to jump through.
It may also be worth your while doing this in advance, being able to produce the report and having it included in your file when sent to the IAA may save some time.
Of course this cost 50 for my GP, and about another 300 I think for a consultants visit and his interpretation of the test, on top of the medical, but if it means you pass, well there's no price on that.
Good luck.
