There are a lot of medicines that help to bring the temperature down. In all preparations says that taking the same drug should be no more than 6-8 hours between doses. And what if the temperature does not fall, or if an hour after taking the drug, it rises again. The main thing is not to cover the child with warm blankets, even if he chills. If the child wears diapers you have to take them off. If the child's legs are hot, then no socks. Rubdown by vodka or vinegar diluted with water helps very well.
We also put Thieves essential oil on their feet which usually takes care of infection because it's antibacterial and of course, brings the temperature down.
I've never heard of covering them even with a fever, our children usually kick the blankets off if they are too hot.
We wouldn't ever use the vodka one since we don't drink and I'd have the same concerns Leah voiced.
