The need for anti-inflammatory drugs after a fever in children needs to be differentiated according to the nature of the specific cause of the fever: first, the situation that requires anti-inflammatory drugs. If the fever is caused by bacterial infection or Mycoplasma pneumoniae infection, the child should be given antibacterial drugs such as cephalosporin, amoxicillin or erythromycin or roxithromycin for timely anti-inflammation. Secondly, there is no need to take anti-inflammatory drugs for the situation. If the fever is a viral infection and the child is suffering from indigestion or an abnormal immune system, there is no need to give the child anti-inflammatory drugs at this time. If the fever is caused by Kawasaki disease, it is only necessary to apply aspirin and gammaglobulin to the child.
