What should I do if the fever remains high after taking antipyretics more than four times? What could be the cause?

Fever persisting despite more than four doses of antipyretics refers to high fever that remains even after taking fever-reducing medication more than four times. This may be related to factors such as upper respiratory tract infection, autonomic nervous system dysfunction, pneumonia, and others. Standardized treatment should be carried out under medical guidance based on the underlying cause. Specific analyses are as follows:

1. Upper Respiratory Tract Infection

If a person comes into contact with items contaminated by viruses, the virus may invade the body and irritate the upper respiratory tract, leading to an upper respiratory tract infection. Clinically, symptoms such as high fever, cough, and nasal congestion may appear. Under medical guidance, medications such as oseltamivir phosphate capsules and ibuprofen tablets can be used for treatment.

2. Autonomic Nervous System Dysfunction

Long-term mental stress or excessive psychological pressure may trigger a stress response in the brain, resulting in autonomic nervous system dysfunction. Symptoms may include high fever, numbness in limbs, and migratory pain. Under medical guidance, medications such as diazepam tablets and propranolol hydrochloride tablets can be used for treatment.

3. Pneumonia

Living for prolonged periods in crowded, poorly ventilated environments may allow pathogenic bacteria to enter the lungs, causing irritation and triggering inflammatory infection. Common clinical manifestations include high fever, cough, and sputum production. Under medical guidance, medications such as amoxicillin capsules and cefuroxime axetil tablets can be used for treatment.

In addition to the above relatively common causes, persistent fever may also be associated with conditions such as encephalitis, leukemia, and malignant lymphoma. It is important to seek timely medical evaluation for appropriate diagnostic tests and follow physician recommendations for treatment.
