I’ve been taking ibuprofen for almost 3 hours and my fever is still not going down.

Fever patients taking ibuprofen for 3 hours is not yet fever, may be caused by the patient’s weak constitution, or the primary cause of the disease is not under control, different reasons, using different ways.
1. Weak body: some patients with weak immunity may have a low fever for a long time after the fever does not go down, you can use physical cooling to assist in reducing fever, such as warm water to wipe the body, alcohol to wipe the forehead, drink more warm water.
2. The primary cause of the disease is not controlled: patients due to pneumonia, encephalitis and other primary causes are not controlled, resulting in fever does not go down, you need to do blood routine, C-reactive protein, Mycoplasma pneumoniae antibody and other related tests to identify the primary cause of the disease, targeted treatment.
Fever does not go away, there may be other reasons, it is recommended to go to the hospital in time to avoid delaying the condition.
