When allergic bronchitis occurs, the first step is to find the allergen and then get rid of it in order to reduce the attack of allergic bronchitis most effectively. Secondly, anti-allergy medication is needed for treatment, the main oral medications are loratadine, paracetamol or cetirizine hydrochloride. In the case of allergic bronchitis in infants and children, dexloratadine is more effective as an anti-allergic treatment. If the symptoms of cough are more severe, hormonal drugs are also needed for treatment. At this time, oral administration is not recommended, and nebulized inhalation of terbutaline sulfate and budesonide is recommended. Terbutaline sulfate is a bronchodilator, which can effectively reduce the symptoms of cough, and budesonide is a glucocorticoid, which can reduce the local inflammatory response and relieve the symptoms of allergy. When allergic bronchitis occurs, it is also easy to combine with bacterial infection. If bacterial infection occurs, it also needs to be treated with antibiotics at the same time, and oral cefixime is recommended.
