Saline is not generally useful in treating rhinitis, but it can be used to relieve the discomfort caused by rhinitis and is beneficial in promoting the cure of the disease. Patients with rhinitis need to clarify the cause of the disease and follow medical advice to avoid the use of unauthorized means to affect the healing of the disease. The saline rinses the nasal cavity, which can not only improve the ciliary movement of the nasal mucosa and help remove pathogenic bacteria and their metabolites from the surface of the nasal cavity, but also enhance the ability of the nasal mucosa to absorb drugs. Therefore, patients can use saline with medication for rhinitis to enhance the recovery process of inflammation and promote the cure of rhinitis. However, saline does not have a bactericidal effect and cannot be used alone to treat rhinitis. Clinical rhinitis includes many types, and depending on the cause and pathology of rhinitis, the clinical drugs needed are different. Common drugs include budesonide nasal spray and mometasone furoate nasal spray to relieve inflammation; cetirizine hydrochloride tablets and loratadine tablets as anti-allergy drugs; and hydroxymetazoline hydrochloride spray to relieve nasal congestion. The main efficacy of different drugs is different, and patients may also induce side effects after using them, so they need to strictly follow the instructions.
