What should I do if fever medicine is taken more than 4 times a day?
Antipyretics should not be taken more than four times a day. If fever persists, alternative antipyretics may be used in rotation. In severe cases, intravenous antibiotic administration may also be employed to alleviate discomfort.
Antipyretic drugs reduce the synthesis of prostaglandins, thereby producing analgesic and anti-inflammatory effects, and lower body temperature by acting on the hypothalamic thermoregulatory center. Fever generally refers to an elevated body temperature. For persistent fever, the medication can be repeated every 4 to 6 hours, but should not exceed four doses within 24 hours. If fever continues after reaching the maximum daily dosage, switching to another antipyretic drug for alternating use may help relieve symptoms. During the fever-reducing period, additional measures such as applying a warm compress to the forehead or using lukewarm water sponge baths can assist in lowering body temperature. It is also important to drink plenty of water to promote metabolism and aid in fever reduction.
If repeated use of antipyretics fails to provide relief, treatments such as intramuscular injection or intravenous infusion of antipyretic medications may be considered. For example, lysine acetylsalicylate injection can be used to achieve more effective fever control.
Taking the same antipyretic repeatedly over a prolonged period may cause damage to the liver and kidneys. In such cases, fever patches or ice packs (used under medical guidance) may be applied to help reduce body temperature.
