When a child has a fever that does not go away even after taking fever-reducing medicine, it means that the fever is very serious and the disease causing the fever is also more serious. At this time, you need to quickly use physical cooling to bring down the child’s temperature a little, otherwise it is easy to have a febrile convulsion. It is recommended to use diluted white wine or alcohol to rub the child’s whole body skin, the effect is still relatively good. If the child is taking cephalosporin or penicillin antibiotics, the diluted white wine or alcohol needs to be replaced with water for wiping, often warm water is more effective. In addition, it is very important to find the cause of the fever. In most cases, it is possible that the fever is caused by a sore throat, which needs to be treated with Pudilan anti-inflammatory oral solution. If a serious respiratory infection occurs, a chest plain film is done to rule out pneumonia. If it is pneumonia, you need to be hospitalized for anti-inflammatory treatment. For other causes of fever that does not go away, you need to go to the hospital quickly for a specific examination to clarify the cause of the fever.
