My daughter was brought into the emergency room last night because she was running  a fever of 103. After the doctor looked over her, he found a slight ear infection, so he prescribed antibiotics, and said to give her tylenol every 4 hours which we are doing, but as soon as the tylenol wears off, especially in the evening her temperature goes back up, im not sure whether we should be worried or if her body just needs another 24 hours to let the antibiotics work, and thats why shes still running a fever.
Hello. I just read through your question. Typically, when a child has an illness that produces fever and antibiotics are prescribed, we expect the fever to last another 2-3 days before resolving. This means that what you are observing in your daughter is not unusual. You can continue to use the Tylenol. If the fever persists beyond a third day, I recommend having her re-examined.
