Allergic rhinitis is a common rhinological disease with clinical manifestations such as sneezing, clear snot, nasal congestion, and lacrimation, etc. In severe cases, headache, dizziness, and loss of smell may occur. Treatment is mainly pharmacological, while other treatments include immunotherapy (desensitization therapy) and surgery. Allergic rhinitis is a special kind of inflammation, and pharmacological treatment mainly uses anti-allergic drugs, usually without antibiotics. Commonly used clinical medications include nasal spray hormones (e.g., coleus, norocort, nexium), antihistamines (e.g., keratan, cetirizine, levocetirizine, desloratadine), and anti-leukotrienes (e.g., montelukast). Treatment options such as herbal medicine and acupuncture are not recommended. The use of drugs: 1. If the symptoms are mild and of short duration, you can take oral antihistamines for treatment. 2.If the symptoms are severe and each attack lasts for more than a month, you can use nasal hormone spray and combine oral antihistamines for the first week. 3. If there are tracheal symptoms, such as cough, you can use anti-leukotriene drugs in combination. Precautions for medication: 1. Nasal spray hormone is the main anti-allergic drug, use it according to the standard dose, the pay effect is mild and can be used for a long time. 2. The efficacy of oral antihistamines will be significantly reduced with long-term use. 3.The use of nasal spray hormone should be adhered to daily, and should be continued for a period of time after the symptoms are completely controlled. For those who do not want to use drug therapy and have clear allergen, immunotherapy can be considered. The disadvantage is that the treatment time is long and partly ineffective. For those who are ineffective in medication or unwilling to use medication, especially those with severe symptoms of clear runny nose, surgical treatment can be considered to improve the symptoms by cutting the pterygoid nerve.
