I suffer from (severe) hayfever and all year round asthma...(nebulizer the works...sigh!)
 Hayfever cure is a clever little nasal spray called Flixonase...I think it can only be prescribed in the dosage I have but can be bought over the counter in a smaller dosage. 
 Works only when taken EVERY day through the hayfever season but I wouldn't be without it. I actually panic if I run too low and have to go a day whilst waiting for the prescription, because I know that the effects of the hayfever bring with it severe asthma attacks
 
  I have tried Triludan, piriton, piroton forte, benalyn allergy, optrex, the honey thing and various other stuff. Ive been taking this for about 4 years and is the only thing that has ever really worked.
