At what temperature can you take ibuprofen for a fever?

　　Ibuprofen belongs to the class of antipyretic analgesics and is commonly available in tablet and capsule forms. Generally, ibuprofen can be taken when fever reaches 38.5°C or higher. However, if the temperature hasn't reached this level but is accompanied by significant discomfort, it may also be used after evaluation, while attention should be paid to proper medication use. Detailed explanation is as follows:

　　For healthy adults and children over six months of age, when body temperature rises to 38.5°C or higher accompanied by discomfort such as headache and muscle pain, taking ibuprofen can effectively reduce fever and relieve symptoms. If the temperature is below 38.5°C, but significant fatigue, listlessness, or other conditions affecting normal life occur due to fever, a small dose may also be taken to improve the condition. However, it should be noted that self-administration is not recommended for infants under six months old and usage should be carefully evaluated according to specific circumstances. When taking ibuprofen, the dosage must strictly follow age and weight guidelines to avoid overdose or repeated doses within a short period.

　　Physical cooling methods can be used during medication, such as wiping the forehead, armpits, and other areas with lukewarm water to help lower body temperature. In daily life, medications should be stored out of reach of children to ensure safe usage.
