Just reporting in on our 3-year-old - we seem to have got through an attack of asthma without prednisolone. What a break-through! We had another good night's sleep - so rare during asthma bouts in the past, and there is a definite improvement on yesterday. Normally his escalating asthma never turns around without corticosteroids. I guess it is early days yet but I am really getting faith in the possibility of sulphite preservatives aggravating the sensitive airways and adding to the other irritations (virus, allergens, irritating particles) to create asthma. It is great to think that we can have some control over one of the components and lessen the health aggravation. - member of the failsafe3 email group
