# Why does infant Tylenol say to ask a doctor under age 2?

Canonical URL: https://kintoolkit.com/questions/infant-tylenol-under-2-years

The US Infants’ Tylenol liquid shown here contains acetaminophen 160 mg per 5 mL. Its under-2-years or under-24-lb direction is to ask a healthcare provider. The word “infant” does not mean the package supplies an amount for every baby.

## Newborn, 5-pound baby or 6-month-old searches

A search for a 5-pound newborn, 6-month-old, 9-month-old, 12-month-old or 18-month-old does not supply the missing label instruction. Do not estimate an amount from a search snippet, divide an older child’s amount or use a higher weight to bypass the age restriction.

## What if the baby weighs 24 lb or more?

Weight-first directions do not remove age restrictions. If age and weight point to different rows, clarify which directions apply with the child’s clinician or pharmacist before giving an amount.

## Check the package and the supplied device

The supported infant and children’s liquids share a printed strength, but their packaging and directions still need to be checked separately. Other countries, formulations or combination medicines may differ. If a clinician has supplied instructions, confirm them against the exact bottle and its measuring units.
