drugs that reduce body temperature in situations such as fever. [cite web |url=http://www.merriam-webster.com/dictionary/antipyretic |title=Definition of antipyretic|accessdate=2007-12-19 |format= |work=Merriam-Webster Online Dictionary] However, they will not affect the normal body temperature if one does not have fever.
Antipyretics cause the
hypothalamusto override an interleukin-induced increase in temperature. The body will then work to lower the temperature and the result is a reduction in fever.
Most are also used for other purposes. For example, the most common antipyretics in the United States are
aspirinand paracetamol(acetaminophen), which are used primarily as pain relievers. NSAIDs are antipyretic, anti-inflammatory, and pain relievers. There is some debate over the appropriate use of such medications: fever is part of the body's immune response to infection.
Herbal remedies with a fever-reducing effect are called febrifuges, and include
catnip, chamomile, sage, wormwood and yarrow. However, the term "febrifuge" can also refer to a refrigerant, such as topical alcohol, which cools the body by physically removing heat rather than modifying the body's responses. This is not recommended currently, because alcohol can be transferred through the skin and affect the liver. In addition, alcohol slightly raises the body temperature before it brings it down, which, if the fever is already very high could cause permanent damage.Fact|date=April 2007.
