Ibuprofen suspension belongs to the central thermoregulatory class of antipyretic drugs. It is generally not recommended when the body temperature does not exceed 38 degrees. It is only recommended when the body temperature exceeds 38.5 degrees and the effect of fever reduction is not obvious with other drugs. Patients should drink plenty of boiled water and take the medication again at intervals of at least four to six hours. Patients may also take ordinary antipyretic drugs if they are accompanied by significant generalized aches and discomfort. If the effect of reducing fever is not obvious even after using ibuprofen suspension, it is recommended to go to a regular hospital promptly.
