The patient has had a high fever of over 39°C; how to reduce the temperature?

The patient has persistent high fever with a body temperature above 39°C, requiring etiological treatment to reduce the fever. Common causes include viral influenza, mycoplasma pneumonia, and lobar pneumonia. Specific analyses are as follows:

1. Viral Influenza

Infection with viruses such as parainfluenza virus or respiratory syncytial virus can lead to viral influenza, resulting in high fever with body temperature consistently above 39°C. Under medical guidance, antiviral medications like oseltamivir phosphate granules, ribavirin granules, or amantadine hydrochloride tablets may be used to eliminate pathogens and alleviate symptoms. Additionally, physical cooling methods such as cold compresses and warm water sponge baths can also effectively help reduce body temperature.

2. Mycoplasma Pneumonia

Persistent fever above 39°C caused by infection with Mycoplasma leading to mycoplasma pneumonia is usually treated under medical advice with macrolide antibiotics such as azithromycin granules, roxithromycin tablets, or erythromycin tablets to reduce infection and promote fever reduction. Additionally, non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen capsules, ibuprofen tablets, or acetaminophen tablets may be used as directed by a physician for fever management.

3. Lobar Pneumonia

Lobar pneumonia caused by pathogens such as Haemophilus influenzae or Streptococcus pneumoniae can result in fever exceeding 39°C. Typically, under medical supervision, antibiotics such as levofloxacin hydrochloride capsules, amoxicillin capsules, or moxifloxacin capsules are prescribed to inhibit pathogens, improve the condition, and lower body temperature. It is also important to drink plenty of fluids to promote heat dissipation and assist in temperature regulation.

Furthermore, systemic lupus erythematosus may also cause elevated body temperature. After seeking medical care, appropriate examinations should be conducted under a physician's guidance to determine the underlying cause and initiate suitable treatment, which will help improve fever symptoms.
