The condition of allergic bronchitis asthma occurs. The first thing to do is to treat the allergy. You need to go to the hospital to check the allergens and get rid of them quickly. Then take anti-allergy medication, such as loratadine, paracetamol, or cetirizine hydrochloride for adults. In children, dexloratadine can be used for anti-allergy treatment. In the case of bronchitis, anti-inflammatory treatment with appropriate antibiotics or antiviral drugs depending on the type of infection is more effective. Usually intravenous drip medications are needed, and oral medications are often not effective enough. For asthma symptoms, bronchodilators and glucocorticoids are needed for relief and treatment, and terbutaline sulfate and budesonide can be inhaled by nebulizer for long-term treatment. It is also recommended to chew a chewable tablet of montelukast sodium before going to bed, which is a leukotriene inhibitor that can prevent nighttime asthma attacks and is very effective in controlling asthma.
