Bronchiolitis typically lasts for two to three weeks. The majority of children with bronchiolitis can be cared for at home with supportive care. It's important to be alert for changes in breathing difficulty, such as struggling for each breath, being unable to speak or cry because of difficulty breathing, or making grunting noises with each breath.
Because viruses cause bronchiolitis, antibiotics — which are used to treat infections caused by bacteria — aren't effective against it. If your child has an associated bacterial infection, such as pneumonia, your doctor may prescribe an antibiotic for that.
Drugs that open the airways (bronchodilators) haven't been found to be routinely helpful. But your doctor may elect to try a nebulized albuterol treatment to see if it helps.
Oral corticosteroid medications and pounding on the chest to loosen mucus (chest physiotherapy) have not been shown to be effective treatments for bronchiolitis and are not recommended.
A tiny percentage of children need hospital care to manage their condition. At the hospital, your child may receive humidified oxygen to maintain sufficient oxygen in the blood, and perhaps fluids through a vein (intravenously) to prevent dehydration. In severe cases, a tube may be inserted into the windpipe (trachea) to help the child's breathing.
