WHO-ARIA recommends the following treatment principles: Avoidance of inhalable allergens: As mentioned before, allergens can be avoided as much as possible for those with clear allergens, which is an important part of the treatment strategy. Health education for patients: making patients aware of the pathogenesis and characteristics of allergic rhinitis and actively participating in the treatment are important factors in achieving good outcomes. Drug therapy: antihistamines are currently applied, which are the first-line drugs of choice for the treatment of allergic rhinitis. Patients are advised to take oral antihistamine H1 receptor drugs during the exacerbation period, and if the symptoms are mild, antihistamines such as benzhydramine and paracetamol can be taken. However, these are first-generation antihistamines with fast onset of action and can rapidly control symptoms 0.5 to 1 hour after taking the drug, but have side effects such as drowsiness and sleepiness. Nowadays, the second generation antihistamines, such as keratan, centrum, etc., have been used clinically, which are not only effective, but also have no side effects such as drowsiness and sleepiness. In order to reduce the swelling and obstruction of the nasal mucosa at the onset, it is often necessary to apply sympathetic alpha receptor stimulants in local drops to constrict blood vessels. The most commonly used are 1% ephedrine or 0.5% furacilin ephedrine. In addition, adrenocorticosteroids have non-specific anti-inflammatory effects and are the first-line drugs for the treatment of allergic rhinitis and can be used for patients with moderate to severe allergic rhinitis. Nasal drops or aerosols such as co-corticosteroids are usually used, which have significant effects on sneezing, nasal runny nose, nasal congestion and loss of smell. Immunotherapy: This therapy can be tried for patients who find clear inhalation antigens or who have combined asthma. However, the standard Wa treatment vaccine should be preferred as a matter of routine. The efficacy and safety are controversial and the indications should be strictly controlled. Surgical intervention: For a small number of patients for whom pharmacological treatment is ineffective, surgical intervention may be chosen as appropriate.
