The infant chart lists 6–11 months and 12–23 months. For babies under 6 months, ask a healthcare provider. Do not reuse a liquid amount from Children’s Motrin: its concentration differs.
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.
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.

|---|---|---|---|
| Under 12 | Under 6 months | Ask your child’s doctor | Under 12 lb |

Infants’ drops contain 50 mg per 1.25 mL; Children’s suspension contains 100 mg per 5 mL. Select the actual bottle and use its supplied measuring device. The tool does not convert doses between concentrations.
Read the manufacturer’s full guidance
For the listed infant label groups, the manufacturer says to repeat every 6–8 hours if needed, no more than four times a day. Timing does not override the under-6-month ask-provider boundary. Read the complete directions and warnings on your package.
The manufacturer pairs 6–11 months with 12–17 lb and 12–23 months with 18–23 lb. Use weight if known; otherwise use age, while respecting the label’s age limits. If the printed bands do not fit or the instructions conflict, ask a pharmacist or clinician rather than rounding into a row.
Use the device supplied with your Infants’ Motrin bottle. If its markings are unclear or do not match the instructed amount, ask a pharmacist for help. Do not estimate from a different syringe or convert the amount for Children’s Motrin.
