Rhinitis in children is common due to colds, allergies, etc. Depending on the characteristics of the disease, the medication and treatment effects are different, and there is usually no eradication of the disease. Usually acute rhinitis is a cold, can be treated with anti-cold medication, usually rhinitis in 5-7 days can be completely controlled. If it is allergic rhinitis, you can give your child oral antihistamines (e.g. cetirizine hydrochloride drops, etc.), or you can use hormone nasal sprays, such as fluticasone nasal spray, etc. If the nasal congestion is severe, you can also use a short-term nasal spray. If nasal congestion is severe, a short-term rinse with physiologic sea saline can also be used. Often seasonal allergic rhinitis can be completely controlled if the season passes. Often rhinitis can be completely controlled with treatment, but there is no guarantee that it will not recur after it is cured. When your child has rhinitis, it is important to take him or her to the hospital to determine the cause of the disease and to provide appropriate interventions to address the cause of the disease.
