Ibuprofen suspension is an antipyretic and analgesic drug commonly used in pediatrics. It is indicated mainly for patients with body temperature over 38.5°C. Its specific dosage is calculated according to body weight. At the same time, the dosage is not more than 4 times a day, and the time interval between the first and second doses is at least 4-6 hours. It is only for reducing fever, it has no therapeutic effect on the cause of fever. Therefore, if the fever is only used to reduce the fever, it cannot be cured if the primary disease is not treated.
