The causes of nasal congestion and sneezing in newborns include the following: First, it is caused by upper respiratory tract infection. If a newborn gets cold after blowing, it leads to viral infection, which results in nasal congestion, sneezing, and even fever and cough. Common viruses include rhinovirus, parainfluenza virus, influenza virus and so on. For this situation, parents only need to give their children Chinese medicine to clear the heat and detoxify the toxin. If the nasal congestion is serious, you can apply furosemide nasal drops to your child. Secondly, the cause of children’s nasal congestion and sneezing is caused by rhinitis. If a newborn has rhinitis, he or she will also have nasal congestion and sneezing. For neonatal rhinitis, parents need to give their children timely application of nasal glucocorticoids, such as Renolcort, etc. The symptoms of nasal congestion and sneezing in neonatal rhinitis are usually maintained for more than two weeks.
