Allergic rhinitis patients often have an atopic constitution, which has certain genetic and familial characteristics, and is also prone to allergic diseases such as allergic cough, bronchial asthma, eczema, etc. Common contact allergens for rhinitis include dust mites, mold, pollen, animal dander, etc. The common allergens in autumn mainly come from wind pollinated pollen of trees and grasses. Proper use of nasal preparations can achieve twice the result with half the effort. Nasal decongestants have a fast effect, but should not be used in large quantities, for a long time, or continuously. Nasal corticosteroids, on the other hand, have the opposite effect. The best therapeutic effect may take several days or weeks, and intermittent medication may not be effective. Continuous medication should be used instead. Nasal spray is a topical medication with low systemic bioavailability. Proper use can rarely cause side effects such as obesity and osteoporosis. Before using nasal spray for the first time, press down a few times to ensure even spraying of the medication. Then keep your head upright, spray your left hand on your right nose, and spray your right hand on your left nose. The nozzle should be directed towards the inner corner of the same nostril to avoid damaging the nasal septum and causing nosebleeds. When spraying, inhale through the nose and press the nozzle to the end to complete a spray. Prevention of allergic rhinitis. Firstly, it is necessary to maintain indoor cleanliness, ensure good air circulation, dry bedding frequently, clean air conditioning filters regularly, stay away from plush toys, avoid carpets as much as possible, and dry clothes in cabinets before wearing them during seasonal changes. Secondly, dust mites in the living environment can be removed by using mite removal agents, adjusting temperature and humidity, and reducing the chances of inhaling mite allergens. Furthermore, outdoor activities can be reduced appropriately in spring and autumn, and allergens can be isolated indoors as much as possible. During outdoor outings, effective pollen barrier agents can be applied or pollen isolation masks and eye masks can be worn to reduce or eliminate exposure to pollen. In addition, it is also possible to consistently flush the nasal cavity with physiological saline before the arrival of allergy season to prevent the occurrence of allergic rhinitis. (New Society)
