Commonly used therapeutic drugs for allergic rhinitis in children mainly include antihistamines, glucocorticoids, nasal mucosal decongestants, etc., but their effects vary from person to person, and it is impossible to say what is the most safe and effective. 1. Antihistamines: such as loratadine, cetirizine, etc. can be anti-allergic, such drugs are prohibited for those who are allergic to them, and the process of using the drug may have adverse reactions such as fatigue and dry mouth. 2. Glucocorticosteroids: such as budesonide, fluticasone, etc., more intranasal sprays to strengthen the local effect and reduce systemic adverse reactions. This kind of drug is prohibited for those who are allergic to it, and the adverse reactions include nosebleed, headache, and so on. 3. Decongestants: such as hydroxymetazoline, furosemide nasal drops, etc., often used to assist in relieving symptoms of nasal congestion. This kind of drug is prohibited for people with dry nasal cavity, adverse reactions include burning sensation in the nose, dizziness and so on. However, it should be noted that, in addition to the above drugs, there are still other types of drugs available in clinical treatment, and the specific efficacy and response of different drugs can still have individual differences. Therefore, there is no such thing as the “safest and most effective” drug for all patients. In addition, it should be noted that there are often age or dosage restrictions on the use of children’s medications, so children with a confirmed diagnosis of allergic rhinitis must be guided by a doctor for the selection of drugs and standardized use. Do not blindly use drugs or increase or decrease the amount of drugs, in order to avoid improper intervention, resulting in adverse consequences.
