1, antipyretic drugs need to be taken only when fever, do not use indiscriminately when not fever, antipyretic drugs do not have an early preventive effect on fever. 2, do not forget the physical cooling. Pediatric fever is different from adults, especially infants and young children, physical cooling is faster and has fewer side effects, which is better than drug cooling. 3, pediatric sweat glands are not developed, not easy to “sweat”. Do not give children more wear more cover to “cover the sweat”, which not only can not cool down but will make the child’s body temperature soar, and even febrile convulsions. 4, taking antipyretic drugs interval is generally not more than 4-6 hours, even if the temperature has dropped, but also to re-measure the temperature after 4 hours. 5, the body temperature recedes too quickly, sweating too much, prone to deficiency, so children should drink water frequently, sometimes with some salt, drinks can not replace plain water. 6, pay attention to the phenomenon of temperature inversion, referring to the baby soon after taking antipyretic drugs (usually within 20 minutes), the body temperature did not fall but rise, after taking drugs 20 ~ 40 minutes before the body temperature really began to fall. Don’t rush to give your baby additional antipyretic medicine as soon as you find out that the temperature has risen, so as not to cause an overdose.
