If a six-month-old child has a high fever that does not go away, parents can deal with it from the following aspects: 1. Take antipyretic drugs in a timely manner. If the child’s axillary temperature exceeds 38.5 degrees, it is necessary to take antipyretic drugs, such as ibuprofen or acetaminophen, which are relatively safe and have relatively few side effects, and the effect is also relatively good. The child will start to sweat slowly for about 30-40 minutes after taking the antipyretic medication, and the body temperature will slowly drop after sweating. 2. Replenish water in a timely manner. The reason is that the antipyretic drugs work only when the child’s body is well hydrated, so it is very important to give the child additional water. The increase in water will increase the amount of urine and help the inflammation in the body to subside. 3. If your child is suffering from a high fever caused by a bacterial infection, prompt anti-infection treatment such as cephalosporin is needed to fundamentally solve the situation of high fever.
