In children with allergic rhinitis we recommend avoiding allergens and desensitization as much as possible, especially in children with asthma. In addition, the internal organs of children are not yet mature, and long-term use of a particular anti-allergic drug or hormone will not only make the drug ineffective, but also affect the organs. Medication recommendations are to use topical nasal medication as much as possible, but special attention should be paid to the age of application, recommended dose and adverse effects of each type of medication. The following points should be noted in the treatment: 1. For milder cases, 4% sodium cromoglycate nasal spray can be used, as sodium cromoglycate is very safe and basically has no side effects, especially for children, followed by intranasal antihistamines (levocabastine, etc.) which also have fewer side effects. In addition, oral anti-leukotriene receptor antagonists (montelukast, etc.) or second-generation antihistamines (loratadine, cetirizine, etc.) can be used, and it has been clinically proven that long-term oral treatment with these drugs is safe for younger children. 2, severe symptoms, can use a new generation of steroids, such as mometasone furoate and other nasal spray, once a day in the morning, the dose should be half of the adult dose or lower. Because these drugs have fewer side effects, the impact on children’s development is minimal, if poor control can be combined with antihistamines and leukotriene receptor antagonists. 3, the use of the above drugs must strictly follow medical advice to control the drug dose. Parents should always observe the effect of children’s use and contact with doctors in time. For patients with long-term nasal hormone use, if parents are worried about the side effects, they can measure the child’s height regularly every 1-2 months, and if there is no change, they should consult with the doctor if the hormone has an effect on growth.
