Cough and nasal congestion are common in upper respiratory tract de infection (common such as the common cold), allergic rhinitis non-allergic rhinitis, especially the common cold and allergic rhinitis confusion, the former generally about 1 week of the course of the disease can be self-healing, while the allergic rhinitis people have more allergies, and more in some specific environment, if not treated, the course of the disease will be long and recurrent. In case of upper respiratory tract infection, first generation antihistamines (paracetamol) and decongestants (pseudoephedrine) are preferred to improve symptoms, and most compounded cold medicines contain these two ingredients, care should be taken to avoid repeated medication leading to drug accumulation and adverse reactions, and most symptoms can be relieved within a few days to two weeks. The first choice for those with allergic rhinitis is nasal inhalation glucocorticoids (such as budesonide suspension) and second-generation antihistamines (cetirizine, loratadine, etc.), symptoms can be quickly relieved, nasal inhalation glucocorticoids need to be used for several days or even 2 weeks to achieve maximum efficacy, it is also important to avoid and reduce exposure to allergic pathogens, general tertiary care hospitals can check allergens. Therefore, it is important to find the cause of nasal congestion and cough in order to provide targeted treatment. The common cold and non-allergic rhinitis are mainly about reducing nasal mucosal congestion and airway hyperresponsiveness. Allergic rhinitis is mainly to avoid contact with allergens, oral antihistamines of the second generation and inhalation of glucocorticoids through the nose at the onset.
