If the child coughs a lot, parents are advised to pay attention to buying cough medicines with phlegm-suppressing or cough-suppressing effects, and it is better to take the relevant medicines under the guidance of a doctor. Commonly prescribed drugs include amoxicillin clavulanic acid potassium granules, compound aminophenalkylamine granules, cefaclor granules, etc. These medications can provide anti-inflammatory effects with quick results. However, prescription drugs usually have potential effects and special requirements for the method and timing of administration, and must be used under the guidance of a doctor. Mothers should not give their babies prescription medications on their own. Commonly used over-the-counter medications include pediatric cough syrup, compound licorice tablets, lung power cough combination, pediatric pulmonary cough granules, Shuanghuanglian oral liquid, jinyinhua granules, coughing tablets, doll’s cold and flu punch, dextromethorphan guaiacamyl ether syrup, strong loquat, pediatric lung fever and cough granules, pediatric coughing and wheezing granules. To prevent dry cough in babies, we should pay attention to keeping the air inside the house fresh and regulating the room temperature, which is 25℃ to 28℃, called neutral temperature. If the environment is too dry and the air humidity drops, the mucous membrane becomes dry and brittle, small blood vessels may rupture and bleed, cilia movement is restricted, and sputum is not easily coughed out.
