Before the cause of recurrent fever is clear, oral antipyretic drugs such as acetaminophen, ibuprofen and aspirin can be used first, or cold glucose sodium chloride injection can be infused to cool down the temperature quickly. After the cause of the illness is identified, the primary illness is treated for the cause. Usually when the primary illness is cured, the fever will also be relieved or cured. For example, recurrent fever due to brucellosis can be treated with a triple antibacterial drug combination of levofloxacin + doxycycline + rifampicin.
