Can you tell me how much Tylenol (160 mg per 5 ml) and Advil (100 mg per 5 ml) I can give him?

For a child weighing 15.8 kg, the recommended dose of Tylenol 160mg/5ml is 7 ml every 4 to 6 hours, up to a maximum of 5 times in a 24-hour period. For Advil 100mg/5ml, the dose is also 7 ml every 6 to 8 hours, with a maximum of 4 times per day, ideally taken with food.
