If a child has symptoms of runny nose, first of all, you need to observe the color of the child’s nose, if it is yellow or green, it is usually caused by bacterial infection. You need to give the child antibiotics for treatment, if the penicillin is not allergic, you can give the child pediatric amoxicillin granules. If the case is clear nasal discharge and sneezing is more frequent, it is likely to be allergic rhinitis. At this time, it is best to give the child anti-allergic drugs, such as dextran, and then go to the hospital to check the relevant allergens and avoid contact with them in the future. If the diagnosis is not allergic rhinitis, it may be a viral cold. This time you need to give your child antiviral drugs and cold medicine for treatment, such as busulfan anti-inflammatory oral liquid and pediatric aminophenol flavonamide granules, the effect is still good.
