Question:

My child was prescribed a 7-day course of antibiotics, and we are currently on day 4. The runny nose and cough have mostly subsided. However, for the past few days, my child has had a mild fever of around 37.6°C in the afternoons, while their morning temperature is about 37.3°C. Their normal body temperature is usually 37.0°C to 37.2°C.
Should I visit the doctor again to get a prescription for additional antibiotics? I am worried because the current medication only lasts until Sunday.
Answer:
It is completely understandable to be worried about a lingering mild fever while your child is on antibiotics. Fortunately, it is a great sign that their respiratory symptoms are improving.
Current Assessment:
• Since the runny nose and cough have mostly subsided, your child is showing a positive response to the antibiotics.
• An afternoon temperature of 37.6°C is generally considered within the normal range, as it is only about 0.4°C higher than their baseline temperature.
• The morning temperature is already almost back to normal.
Important Notes on Antibiotics:
• Please make sure to complete the entire 7-day course of antibiotics exactly as prescribed.
• Even if symptoms improve, stopping the medication early can increase the risk of antibiotic resistance.
• The current mild afternoon temperature elevation is highly likely just a normal part of the body's recovery process.
When to Revisit the Doctor:
• If a true fever of 38.0°C or higher develops.
• If new symptoms appear, such as ear pain or difficulty breathing.
• If the mild fever persists after Sunday.
• If your child becomes noticeably lethargic or refuses to eat or drink.
For now, continue giving the antibiotics until the prescription is finished and closely observe your child's condition. Make sure they get plenty of rest and stay well-hydrated over the weekend. If the mild fever is still present on Monday, please visit your pediatrician for a follow-up evaluation.
