4yr old has middle ear infection with a fever of 38.9c. also chesty cough but chest is clear. on amoxicillin today & panadol (acetaminophen). when worry about temp?

Time needs: Any time you start an antibiotic you are playing catch-up with an established infection.It will take time for absorbed antibiotic to achieve a level in the kids body that will start winning the battle with the germ.With Amoxicillin,I expect the fever to start going down within 36 hours if it is the right drug for that germ.If the kid has other issues, like a flu, it may cause the fever to linger

If temp is >40.5C: contact your doctor if it doesn't respond to another dose of Panadol (acetaminophen) and cool compresses within 30 minutes. Fever is the body's way of fighting infection, and in it self is not harmful at lower numbers except your child will feel uncomfortable and is more likely to get dehydrated if not drinking enough fluids. See doctor if fever >48 hours or your child seems more ill.
