Just found this forum. Blair will be 4 next week - has had a diagnosis of asthma and allergic rhinitis for over a year - infact nearly 2. I have numerous arguments with health professionals (the norm) put in complaints about 2 (upheld) - luckily I have a fantastic asthma nurse. His rhinitis (hayfever) is really kicking in and he is so miserable. He takes inhalor every day and singlair, plus has been taking piriton 2,5mls every 4 hours but its not working for him - any suggestions on which antihistamine works best? We live right next to fields so im sure grass pollen is a biggie for him - all help gratefully received!
