Rhinitis committed in April every year is mostly considered as the manifestation of seasonal allergic rhinitis, and the following treatments can be adopted according to the condition: avoiding contact with allergens; medication (symptomatic treatment); immunotherapy (causative treatment); and surgical treatment. 1. Avoiding contact with allergens: actively and effectively avoiding contact with allergens is the key to the treatment and prevention of this disease, which can be achieved by wearing masks when going out and regularly cleaning air-conditioning filters in order to reduce the concentration of disease-causing allergens. 2. Drug therapy: nasal glucocorticoid spray such as budesonide nasal spray, oral antihistamine such as loratadine; oral antileukotriene such as montelukast; nasal saline rinse; local use of pollen blocker. 3. Immunotherapy: for patients allergic to Artemisia, sublingual and subcutaneous immunotherapy can be chosen. 4. Surgical treatment: For some cases where the effect of drugs and immunotherapy is not satisfactory, selective neurotomy, including pterygoid neurotomy, can be considered. If the allergic rhinitis flare-up occurs in April every year, you need to actively seek medical treatment, after clarifying the diagnosis and the extent of the disease, and then follow the doctor’s instructions to standardize the treatment.
