How long can we keep giving him Tylenol before going to the hospital if it doesn't get better?

If the fever has gone down and there are no alarming symptoms, it is generally not necessary to go to the hospital. However, it is important to keep monitoring the situation in case the fever spikes again or if other symptoms worsen. If the fever persists for more than 72 hours or does not respond to the use of pain medication, then it may be necessary to seek medical attention. Keep an eye on any changes in respiratory symptoms and overall well-being of the individual. Make sure to follow the recommended dosage of medication based on weight and consult a healthcare professional if you have any further concerns.
