antipyretic
Antipyretics (), from the Greek anti, ''against'', and pyreticus, ''pertaining to fever'', are substances that reduce fever.〔(【引用サイトリンク】title=Definition of antipyretic )〕 Antipyretics cause the hypothalamus to override a prostaglandin-induced increase in temperature. The body then works to lower the temperature, resulting in a reduction in fever.
Most antipyretic medications have other purposes. The most common antipyretics in the United States are ibuprofen and aspirin, which are used primarily as pain relievers. Non-steroidal anti-inflammatory drugs (NSAIDs) are antipyretic, anti-inflammatory, and pain relievers.
There is some debate over the appropriate use of such medications, as fever is part of the body's immune response to infection. A study published by the Royal Society claims fever suppression causes at least 1% more influenza cases of death, resulting in at least 700 extra deaths per year in the United States alone.
==Non-pharmacological treatment==
Bathing or sponging with lukewarm or cool water can effectively reduce body temperature in those with heat illness but not usually in those with fever.〔(【引用サイトリンク】title=UpToDate Inc )〕 The use of alcohol baths is not an appropriate cooling method, because there have been reported adverse events associated with systemic absorption of alcohol.
