From the Research
For infant Tylenol (acetaminophen) oral suspension dosing, use the weight-based formula of 10-15 mg per kilogram of body weight every 4-6 hours as needed, not exceeding 5 doses in 24 hours, as supported by the most recent and highest quality study 1.
Key Considerations
- Always use the measuring device provided with the medication, not household spoons.
- Infant Tylenol suspension typically comes in a concentration of 160 mg per 5 mL, but check the product label carefully as concentrations can vary.
- Never give adult formulations to infants.
- Contact your pediatrician before giving Tylenol to infants under 3 months old.
- Acetaminophen works by reducing fever and pain by affecting the temperature-regulating center in the brain and blocking pain signals.
Important Reminders
- Always consult your child's healthcare provider if symptoms persist beyond 3 days, fever exceeds 102°F, or if you're unsure about proper dosing for your infant's specific situation.
- The recommended dosing is based on the study by 1, which reviewed published and unpublished pediatric antipyretic data to provide a critical assessment of the 10-15-mg/kg oral dose and the current pediatric oral dosing schedules for acetaminophen.
- Other studies, such as 2 and 3, although relevant to pediatric care, do not directly address the dosing of acetaminophen in infants and are therefore not the primary basis for this recommendation.
