Question:
My 8-year-old son has had a fever for four days. He was diagnosed with pneumonia at the hospital, and the doctor mentioned that if his fever doesn't break by tomorrow, we should consider hospitalization.
For the first day and a half, his temperature was over 39°C, so I gave him ibuprofen on schedule. Since then, his temperature has been fluctuating between 38°C and 38.3°C. Because his overall condition and energy levels are good, I haven't been giving him fever reducers.
My question is: Does giving a fever reducer even for a mild fever (around 38°C) ultimately help cure the fever faster? If a fever lasts for several days, is it better to give a fever reducer even for a low 38°C temperature?
Answer:
Hello. I understand you must be very worried about your son's pneumonia and his lingering fever.
It is quite common for a fever to last for four days during pneumonia treatment. The fact that his temperature has dropped from over 39°C to the low 38s, combined with his good general condition, is actually a very positive sign.
Principles for Using Fever Reducers:
When a child has a temperature in the low 38s, the decision to use a fever reducer should be based purely on the child's comfort level:
• If your child is playing and eating well -> You do not need to give a fever reducer.
• If your child seems uncomfortable, irritable, or has a decreased appetite -> It is helpful to give the medication.
It is important to know that fever reducers do not cure pneumonia or make the underlying illness go away faster. A fever is simply the body's natural response to fighting off an infection. The main role of a fever reducer is just to relieve discomfort and make your child feel better.
Important Monitoring Points:
• If his breathing becomes fast or appears labored, take him to the hospital immediately.
• If he complains of chest pain or if his cough significantly worsens, seek a medical re-evaluation.
• Ensure he stays well-hydrated (you can monitor this by making sure his urine color is light and pale).
Please continue to closely observe his overall condition until your follow-up appointment tomorrow. When you see your doctor, explain the recent fever patterns and his energy levels in detail. The doctor will evaluate his overall state to make the best decision regarding whether hospitalization is necessary.
