You can take medicine when your baby has a cough. Whether you take medicine to treat it depends on the severity of your baby’s cough symptoms. If your baby’s cough is very mild, with a light cough and not much phlegm, and does not affect your child’s eating, sleeping or playing, you can give your baby more water and feed him/her diligently as appropriate, and focus on a light diet in your child’s diet, and your child’s cough may also improve or reach the level of cure, in which case you can not take medicine. If the baby coughs and coughs up phlegm obviously, with more phlegm, you can give symptomatic oral medication to reduce phlegm and cough, commonly used are aminoglutethimide oral solution or pulmonary cough combination, and at the same time, you must drink more water and feed the baby diligently to facilitate the absorption and discharge of phlegm. If the child’s symptoms improve significantly with oral cough medicine, there is no need to take the baby to the hospital for further examination. If there is no significant improvement with oral medication alone, further blood tests should be performed at the hospital to identify the pathogenic bacteria causing the cough, and further medication should be given under the guidance of the doctor.
