In the vast majority of cases, children will experience sweating as well as a decrease in fever after taking ibuprofen for about 40-60 minutes. Ibuprofen is a non-steroidal anti-inflammatory drug, which can be applied promptly when the axillary temperature exceeds 38.5°C. Ibuprofen can effectively lower the body temperature regulating point of children and cause sweating in their bodies. After sweating, a large amount of heat will be taken away, which will effectively lower the child’s body temperature. When giving ibuprofen to children, it is important to take enough water at the same time. If the water is too little, the effect of ibuprofen on children will be reduced. Therefore, after giving ibuprofen to children, it is important to observe the body temperature in time for about 40-60 minutes.
