From the Research
You can give the next dose of Tylenol (acetaminophen) to the 8-month-old child in 4 hours, which would be after the previous dose, considering the recommended dosing interval for infants and children is every 4-6 hours, with a maximum of 5 doses in 24 hours 1. For infants and children, the recommended dosing interval for Tylenol is every 4-6 hours, with a maximum of 5 doses in 24 hours.
- The typical dose for an 8-month-old weighing 9 kg is 90 mg (10 mg/kg) 1.
- This translates to about 2.8 mL of Children's Tylenol liquid (160 mg/5 mL concentration).
- Always use the measuring device provided with the medication for accurate dosing. It's essential to maintain consistent intervals between doses to ensure steady pain relief and fever reduction while avoiding potential overdose.
- If symptoms persist or worsen, consult a healthcare provider. Recent studies have raised concerns about the long-term neurodevelopmental effects of acetaminophen in infants and children, emphasizing the need for cautious use and adherence to recommended dosing guidelines 2. However, the most recent and highest-quality study relevant to dosing intervals in infants and children is from 2013, which provides the basis for the recommended dosing interval of every 4-6 hours 1. Other studies, such as those focusing on intravenous paracetamol dosing in neonates, provide valuable information but are not directly applicable to the question of oral acetaminophen dosing in an 8-month-old infant 3, 4, 5.
