Desloratadine dry suspension is mainly anti-allergic. Desloratadine is a new type of antihistamine, also known as a “third generation” antihistamine, which is mainly anti-allergic. It is mostly used to relieve nasal itching, nasal congestion, sneezing and other symptoms such as itchy eyes, tearing and burning caused by allergic rhinitis; it can also be used for chronic cough caused by airway allergy, variant asthma and allergic pharyngitis. It can also be used for allergic skin lesions such as urticaria, eczema, drug-related dermatitis or solar dermatitis. Desloratadine dry suspension has a powder-like granular appearance, which makes it easier for infants and children to dissolve in water and take orally, and can be taken simultaneously with food and beverages, with no obvious contraindications.
