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 discharge is clear nasal discharge and also has sneezing symptoms, it may be a phenomenon of allergy, if there is a family history of allergy, the possibility of allergy is greater, you can take anti-allergy drugs for treatment, such as Desloratadine. If the runny nose is caused by a cold, paracetamol can also be used at this time.
