What is the reason for the baby's fever after the fever has subsided?

Patient's question:

The baby is 18 months old. A few days ago, they had a fever for 3 days and took medicine, which brought the temperature down. Last night, around 1:30 AM, the temperature was 35.7, and it has stayed at 35.8 until today. What could be the reason? Doctor

Doctor's answer:

The baby has a fever, and after taking the medication, the temperature has come down. Now it's slightly low, at 35.8 degrees. This situation is related to the medication taken during the fever. The fever reduction has altered the body's temperature regulation function to this degree. Generally, if the antipyretic medication is excreted in a few days, the body can gradually recover completely. The above advice is for the question "The baby is 18 months old and had a fever for 3 days and took medication to bring the temperature down." It is hoped that this will be helpful to you. Wishing you good health!
