My 6 year old girl has had nasty cough for a month doc said she isn't asthmatic but prescribed her inhalers is that normal? Xray show small airways

R A D. Reactive Airways Disease, can be the case with your daughter?, which can happen at times after a viral infection and may stay for sometime, it mimicks asthma, inhalers would help. Another problem that needs to ruled out is sinus infection which would cause nasty cough still and flare of asthma symptoms or cough. Asthma would be the diagnosis if we rule the other causes first, wish you both wellnes.
