What should I do if my fever returns to 38.3°C during the recovery phase of pneumonia?

During the convalescent phase of pneumonia, a fever of 38.3°C requires immediate discontinuation of suspected medications, physical cooling to regulate body temperature, replenishment of fluids and electrolytes, close monitoring of symptom changes, and evaluation for possible infection recurrence. If the temperature continues to rise above 38.5°C or is accompanied by symptoms such as difficulty breathing or chest pain, prompt medical attention is necessary.

1. Immediately discontinue suspected medications: Review recently used non-essential drugs to avoid drug-induced fever worsening symptoms. Monitor temperature changes after stopping the medication. Do not switch or resume medications on your own; adjust treatment regimen strictly under medical guidance.

2. Physical cooling and temperature control: Wipe areas with major blood vessels—such as the forehead, neck, armpits, and groin—with lukewarm water. Maintain a comfortable room temperature, reduce clothing and bedding to aid heat dissipation, and avoid alcohol rubs to prevent skin irritation.

3. Replenish fluids and electrolytes: Drink warm water or oral rehydration solutions in small amounts frequently to maintain fluid balance and alleviate dehydration caused by fever. Focus on a light, easily digestible liquid diet.

4. Closely monitor symptom changes: Take and record body temperature regularly, and watch for signs such as worsened cough, bloody sputum, or rapid breathing. Keep detailed records to provide accurate information for medical evaluation.

5. Rule out infection recurrence: Be alert for incomplete resolution of pneumonia or new secondary infections. Pay attention to systemic symptoms such as fatigue, night sweats, and loss of appetite. Seek timely medical evaluation to identify the cause and receive targeted treatment.

During pneumonia recovery, ensure adequate rest and avoid overexertion. Keep indoor spaces well-ventilated to reduce bacterial growth, stay warm to prevent chilling and worsening of condition, and maintain a balanced diet rich in nutrients to strengthen immunity and support full recovery.
