There is no good evidence that any medication consistently helps with bronchiolitis. A small percentage of patients might improve with a beta-agonist airway muscle relaxant aerosol like Ventolin. Aspelone, nebulised Pulmicort/Budoneb, Monte air/Topraz/Sintrine, antibiotics, nebulised adrenaline, nebulised hypertonic saline, cough mixtures, chest physiotherapy… none has been proven to effect a quicker cure, despite being commonly prescribed and used. Antibiotics are only indicated for severe bronchiolitis. Supportive treatment in hospital entails providing oxygen (if needed), managing fever, ensuring adequate fluid intake and managing complications like otitis media and pneumonia (lung infection). In-hospital stay is usually only necessary for a day or two to gauge the course of the disease process. It may take weeks to resolve completely.
