At what temperature should a 4-year-old with an anal temperature of 38 degrees Celsius take fever-reducing medication?

Patient's question:

No

Doctor's answer:

Hello, a baby's temperature is most accurate when measured rectally. If measured under the arm, you need to add 0.5 degrees to get the correct body temperature. Your baby's temperature is a bit high now, so you can give them a suitable amount of fever-reducing medication.
