Question:
I have a question about giving fever reducing medication to my 5-year-old who has the flu. Usually, I wait until the fever reaches 38.5°C before giving medication, but I heard that for the flu, I should give it around 38°C. Should I give the medicine if the temperature goes over 38°C? Currently, my child is complaining of a headache, severe nasal congestion, and feeling cold.
Answer:
When managing a fever for a child diagnosed with the flu, the child's overall comfort level is much more important than the exact number on the thermometer.
Here are the general guidelines for using fever reducers during a flu infection:
Treat the discomfort, not just the number: Even if the temperature is 38°C, if your child is experiencing a headache and chills, you should administer a fever reducer.
If playing well: On the other hand, even if the fever is 38.5°C, if your child is playing well and doesn't seem bothered, you don't necessarily need to give medication.
Flu vs. Common Cold: The flu typically causes more severe body aches and fatigue than a regular cold, so children may feel significantly more uncomfortable even at lower temperatures.
Given your child's current situation—complaining of a headache and feeling cold—you should go ahead and give a fever reducer (such as Acetaminophen or Ibuprofen).
In addition to the medication, please help relieve their symptoms by doing the following:
Encourage plenty of fluid intake (warm water or honey tea can be soothing).
To help with the severe nasal congestion, use a humidifier in their room and apply saline nasal drops or spray.
When to see a doctor again:
Please visit your pediatrician or an urgent care clinic for an in-person evaluation if you notice any of the following warning signs:
Breathing becomes rapid or appears labored.
A high fever persists for more than 3 days.
Signs of dehydration develop (e.g., decreased urine output, dry lips, no tears when crying).
Your child becomes unusually lethargic, difficult to wake, or their consciousness seems clouded.
A fever from the flu typically lasts for 3 to 5 days. The main goal is to keep your child comfortable with fever reducers and ensure they get plenty of rest. It is always hard to see your little one feeling unwell, but you are doing a great job caring for them!
