Your daughter could be suffering from bronchial asthma
not just a plain bronchitis
, so she would improve after ventolin
and of course managed with anti-histamine
to counter tha allergic nature of the disease. The fact that it improves with those medications but eventuallycomes back could onlY mean an inadequately managed disease or the triggering factor is in your household or in her bedroom. Triggering factors include extremes of temperature, dust, pets or hyperallergenic food. Any of these can start an asthmatic episode. Identify the cause and get rid of the asthma. If she reacts with pets, or carpet or stuffed toys, then it should be identfied and eliminated.
