For a month-old infant, Tylenol (acetaminophen) should only be given under direct guidance from a pediatrician or healthcare provider, as infants under 2 months or under 12 weeks old generally should not receive acetaminophen without medical advice due to the need for careful evaluation of fever or symptoms
. If a healthcare provider approves giving acetaminophen to an infant older than 1 month, dosing is typically based on weight rather than age alone. For infants between 4 and 11 months old weighing 12 to 17 pounds (5.5 to 7.9 kg), the usual dose is about 1 mL of infant acetaminophen liquid (which is usually 160 mg/5 mL concentration) every 4 to 6 hours as needed, but not more than 4 doses in 24 hours
. Key points:
- Do not give acetaminophen to infants under 12 weeks without a doctor’s approval
- For infants 1 month old and older, dosing depends on weight; for example, 1 mL for 12–17 lbs infants every 4–6 hours as needed, max 4 doses/day
- Use the dosing syringe or cup provided with the medication for accuracy
- Do not exceed 4 doses in 24 hours to avoid liver toxicity
- Always consult your pediatrician before administering Tylenol to infants this young to ensure safety and correct dosing
If you are unsure or your infant is younger than 3 months, seek medical advice before giving any acetaminophen.
