If an adult has a persistent fever of 38°C caused by bacterial infection, antibiotics may be used as directed by a physician to help reduce inflammation, such as azithromycin or roxithromycin. If the fever is due to a viral infection, antiviral medications such as ganciclovir or acyclovir may be used. If body temperature exceeds 38.5°C, antipyretic medications such as loxoprofen or ibuprofen can be added.
