Desloratadine dry suspension is recommended for use in babies over one year of age. The efficacy and safety of its use in children under one year of age has not been established. Desloratadine is commonly used in the treatment of eczema, atopic dermatitis, urticaria, allergic rhinitis, allergic conjunctivitis, and bronchial asthma and other allergic diseases. In the treatment of bronchial asthma, it can effectively relieve the symptoms of coughing, wheezing and dyspnea. In the treatment of allergic rhinitis, it is also effective in treating symptoms such as runny nose, nasal congestion, nasal itching and sneezing caused by rhinitis. For patients with urticaria, it can effectively relieve itchy skin and other symptoms. Desloratadine does not easily cross the blood-brain barrier, so it rarely causes adverse reactions of drowsiness in patients.
