There is no cure for allergic rhinitis, but symptoms can be improved through treatment, including general treatment, medication, immunotherapy, surgery and so on. Allergic rhinitis is a chronic reactive inflammation of the nasal mucosa. The stimulation of allergens leads to the sensitization of the body, and then the allergens re-enter the nasal cavity and act on the blood vessels, glands and cells, causing allergic reactions and continuous sneezing, itchy nose, nasal congestion, nasal discharge and other symptoms. This disease can not be cured at present, only through targeted treatment to actively control the symptoms. 1. General treatment: avoid contact with allergens. 2. Medication: (1) Antihistamine drugs: such as cetirizine, etc., there may be headache, drowsiness and other adverse reactions, pay attention to alcohol to avoid using. (2) Nasal decongestants: such as hydroxymetazoline hydrochloride spray, etc., the adverse effects of prolonged use can lead to drug rhinitis, note that the continuous use of not more than 7 days. (3) Nasal glucocorticoids: such as mometasone furoate nasal spray, in order to reduce the inflammatory response of the nasal mucosa. Possible adverse reactions are nasal burning, headache, etc. It is contraindicated in untreated localized infections of the nasal mucosa. 3. Immunotherapy: subcutaneous injection or sublingual administration of allergen extracts, through repeated exposure to improve its tolerance to allergens, in order to achieve re-exposure to allergens after the onset of symptoms to reduce or no longer develop the purpose. 4. Surgical treatment: For those who are not satisfied with conservative treatment, surgical treatment, such as pterygoid neurectomy, can be chosen to improve the status of runny nose.
