Allergic rhinitis, also known as allergic rhinitis, is an allergic inflammation of the nasal mucosa that occurs after the body is exposed to allergens, such as dust, mold and pollen. The main manifestations are sneezing, runny nose, itchy nose, blocked nose, and some children are also prone to rhinorrhea. The best treatment for allergic rhinitis is to get rid of the allergen, however, it is difficult for most patients to do so. Allergic rhinitis can be treated with oral anti-allergy drugs and leukotriene receptor antagonists, and long-term regular use of corticosteroid nasal sprays can also improve and control the symptoms of rhinitis. Some parents feel that longer treatment with corticosteroid nasal sprays is needed, worry about the side effects of hormones, or interrupt treatment because their child refuses the nasal sprays, all of which are detrimental to the control of rhinitis. Because the nasal cavity is exposed to the outermost part of the body, any allergic factor can stimulate the nasal cavity. Allergic rhinitis is very difficult to control and easily recurring and needs to be treated under the guidance of an ENT specialist. Parents should carefully observe the symptoms of the affected child, including some subtle and easily ignored habits in life, such as rubbing the nose, rubbing the eyes and other subtle small movements, and provide them to the doctor in a timely and detailed manner. Actively cooperate with the doctor’s treatment and adhere to the medication regimen prescribed by the doctor, and do not terminate the treatment at will according to your own judgment. If you have any doubts about the medication, you should communicate with your doctor before deciding whether to change your treatment plan.
