The child’s body resistance is usually weak after a cold, and at this time viruses tend to invade the baby’s organism and cause a cold, which is an infection of the upper respiratory tract caused by a virus, resulting in a cough. Because of the inflammation in the throat, there is congestion and edema, as well as the secretion of inflammatory exudates, which irritate the throat and cause coughing. Anti-inflammatory treatment or cold medications are often effective at this time. Cold medications such as aminophenol xanthamine pellets, pediatric anerine pellets, aminophenol pseudo-lax dispersible tablets or cold and fever pellets are effective. If the symptoms of cough are heavy, you also need to use cough medicine to relieve phlegm. If you have a dry cough, you can take fenagan syrup. If you have a cough with phlegm, you can take oral aminoglutethimide solution or lung power cough combination.
