Appropriate Dosing
- The recommended dosage for infants is 10-15 mg/kg body weight per dose, administered every 4-6 hours as needed 3, 4

- Always use the measuring device provided with the medication to ensure accurate dosing 6
- Do not exceed 5 doses in 24 hours 4
Common Indications for Acetaminophen in Infants

Important Precautions

Safety Considerations
- While acetaminophen is generally considered safe for short-term use in infants when properly dosed, long-term neurodevelopmental effects have not been thoroughly studied 7
- The most common adverse events are gastrointestinal in nature and generally mild in intensity 4
- Acetaminophen has been shown to be safe for the liver when used as directed in infants 7
Administration Tips

- Calculate the exact dose based on your infant's current weight 5
- Administer the medication at evenly spaced intervals throughout the day if multiple doses are needed 6
- Keep a log of when doses are given to avoid accidental overdosing 4
