There is no such thing as a good cough suppressant for children. Because coughing up phlegm is the body’s normal way of expelling germs, the use of cough suppressants, on the contrary, is not conducive to the expulsion of germs. Therefore, the cause of the disease can be treated with medication: 1. Upper respiratory tract infection: sneezing, nasal congestion, cough, fever, cough and other symptoms. If it is caused by viruses, generally no special medication is needed. If combined with bacterial infection, should follow the doctor to use cefixime, amoxicillin and other antibacterial drugs. You can also take honey on a daily basis to relieve throat discomfort. 2. Pneumonia: mainly fever, shortness of breath, coughing, lack of spirit, refusal of milk and other manifestations. According to the different pathogens of infection, the drugs used are also different. Bacterial pneumonia can use cephalosporin drugs, such as ceftriaxone; Mycoplasma pneumoniae infection can use azithromycin and so on. Cough serious phlegm can use inhalation with acetylcysteine solution and other drugs to relieve. 3. Bronchial asthma: the main symptoms are repeated wheezing, shortness of breath, chest tightness or cough. Some patients may cough up sputum. Medications to control asthma attacks, such as inhaled glucocorticoids (e.g. budesonide suspension for inhalation), need to be given as prescribed. Cough and phlegm in children should be treated with medications that correspond to the cause of the disease. It is recommended that the patient go to the hospital in time to clarify the cause of the disease. If medication is needed, it should be used under the guidance of a doctor.
