If your baby has a runny nose, you need to observe the nature of the nasal discharge first. If it is yellow-purulent nasal discharge, it is likely that there is a bacterial infection in the nasal cavity, or it may be caused by a bacterial cold, both of which need to be treated with antibiotics. For babies, if there is no allergy to penicillin, you can take amoxicillin orally. If amoxicillin has allergy, you can give your child oral cefixime granules for better treatment. If the nasal water is clear nasal discharge, it may be a phenomenon of allergy, often the examination of eosinophils will have elevated, and has a history of exposure to allergens, but also has the symptoms of sneezing, you can take anti-allergic drugs for treatment, such as diclazuridine. If the runny nose is caused by a cold, the baby can be treated with cold medication, such as Anerin granules and pediatric aminophenol pseudo-lax dispersible tablets.
