Thanks for your question on Health Care Magic.
I can understand your concern.
Acute
bronchitis is mostly due to infection.
So antibiotics are mainstay of treatment.
Along with antibiotics, patient needs inhaled bronchodilators, inhaled corticosteroid (ICS),
mucolytic and expectorant drugs.
Antihistamines are also advised for coughing.
Usually recovery achieved in 2-3 weeks.
But sometimes recovery can be delayed. In this situation patient should continue inhaled bronchodilators and inhaled corticosteroid.
So ask your son to continue inhaled treatment.
Hope I have solved your query.
I will be happy to help you further. Wish you good health. Thanks.
