As above people have discussed - I often tell parents this with their kids, to reassure them re swinging fevers- that’s it ok and it’s the immune system doing it’s job. However- I also say, and please correct me if I’m wrong- that from current trial evidence, when groups treated with anti pyretics vs no anti pyretics are compared- there is not a significant difference in length or severity of illness… anyone know if I am talking out of my rear here??
