A quick method to lower a fever is to take an antipyretic, or fever-reducing medication, such as acetaminophen, ibuprofen or aspirin, advises Mayo Clinic. Aspirin is not recommended for children or teenagers. Other measures that can help relieve the discomfort associated with fever include drinking plenty of fluids and resting.
While antipyretics can help temporarily bring down fever, they're not always necessary, notes Mayo Clinic. In general, adults and children 2 years of age and older should only take a fever-reducing medication if their body temperature, typically measured by mouth, is more than 102 degrees Fahrenheit. Otherwise, rest and hydration are usually sufficient. If the fever does not subside despite the medication or persists for longer than three days, medical attention may be necessary.
