All bronchitis attacks in children are caused by infections, most often viral infections, often following a cold. Therefore, antiviral drugs, such as oseltamivir and amantadine, can be chosen for children with bronchitis. If the patient is considered to have a bacterial infection based on clinical symptoms and relevant examinations, a combination of antibiotics is also needed. If there is no history of allergy, azithromycin and cefixime can be chosen. At the same time, treatment for clinical symptoms is needed. If the body temperature exceeds 38.5℃, antipyretic drugs such as ibuprofen suspension need to be given. If cough and sputum are more obvious, cough suppressants such as pediatric lung-heat cough and asthma oral solution and acute branch syrup can be given.
