An infant Tylenol calculator for the US 160 mg/5 mL bottle. For children under 2 years or under 24 lb, the label directs caregivers to a healthcare provider rather than a calculated dose.

## Infants’ Tylenol dosage chart and age limits

Match the 160 mg/5 mL concentration. This page selects the infant bottle and shows its label ranges. The infant branding does not mean a dose is listed for every baby.

## Is infant Tylenol the same concentration as children’s Tylenol?

The US liquids shown here both contain 160 mg per 5 mL. Follow the directions and use the measuring device supplied with your own bottle; do not apply this chart to another strength.


## Supported bottles

| Bottle | Ingredient | Strength | Uses |
| --- | --- | --- | --- |
| Infants’ TYLENOL | Acetaminophen | 160 mg / 5 mL | Weight or age |

US liquid products shown here only. Do not apply these amounts to another strength, formulation or country’s product. Use the measuring device supplied with your bottle and read the full label; this page does not reproduce every warning.

## Infants’ TYLENOL — 160 mg / 5 mL

Use weight if known; otherwise use age. The weight and age columns are alternatives from the label, not a formula. If the child is outside the listed age range or the weight falls outside a printed band, ask a clinician. Do not interpolate.

| Weight (lb) | Age on label | Label amount | Label reference |
| --- | --- | --- | --- |
| Under 24 | Under 2 years | Ask your child’s doctor | [Under 24 lb](https://kintoolkit.com/infant-tylenol-dosage-calculator/160-mg-per-5-ml/under-24-lb) |

Label interval: every 4 hours while symptoms last. No more than 5 doses in 24 hours. Do not combine with another medicine containing acetaminophen.

## Methodology and attribution

KinToolkit organizes the selected US liquid medicine labels into bottle-matching tools and reference tables. The calculator and these tables use the same range lookup, not a continuous weight formula. Manufacturer labels are the primary sources; this summary does not establish an independently validated or clinically reviewed dosing protocol.

## Before using label directions

Verify the active ingredient, concentration and warnings on your own package. KinToolkit is an independent educational tool, not a medical professional or a substitute for your child’s clinician. The brands mentioned above are not affiliated with KinToolkit.
