There are more ways to reduce fever, such as by using ibuprofen or by using fever suppositories or fever patches. But fever is only a symptom, not a disease, and cannot be aimed at reducing fever. If the fever is caused by a cold, it may be caused by an inflammatory infection or a viral infection and requires antiviral treatment and anti-inflammatory treatment. When the infection in the body is effectively controlled, the symptoms of fever will naturally disappear. However, fever caused by disease itself may cause some damage to various functions of the body if a persistent high fever occurs. Therefore, when the body temperature exceeds 38.5℃, it is necessary to treat the disease and reduce the fever at the same time. Depending on the severity of the fever, different medications can be chosen for temperature control.
