The symptoms of a runny nose in the morning are most often caused by a cold that occurs during the night, resulting in the onset of a cold. Once the nasal cavity is infected with virus or bacteria, there will be congestion and edema, which will lead to nasal congestion and secretion of large amounts of inflammatory exudate, resulting in a runny nose. For example, adults can use SensoKang, Aminogalactone capsules or Vitamin C silver warp tablets. In the case of infants and young children, they can be treated with pediatric cold and fever pellets, pediatric blackberry fever pellets or pediatric aminophenol pseudomal dispersible tablets, which are all more effective. If the phenomenon of runny nose occurs, it indicates a combined bacterial infection, which also needs to be treated with antibiotics, if the penicillin is not allergic, you can use amoxicillin or amoxicillin clavulanate potassium.
