How to use the Ibuprofen dosage chart
Follow these steps for safe, accurate dosing:
Weigh your child on a reliable scale (without heavy clothing or diapers for best accuracy).
Find their weight range in the chart’s left column.
Match it to the correct form of ibuprofen (liquid, chewable, or tablet).
Follow frequency guidelines: give every 6–8 hours as needed, but no more than 3–4 doses in 24 hours.
Use only the measuring device included with your child’s medication.
Stay within safe limits: do not exceed 2400 mg in 24 hours overall (weight-based maximums for younger kids are lower).
⚠️ Safety reminder: These are general recommendations. Children with chronic illnesses, dehydration, or who are taking other medications may require different instructions. Always double-check with a healthcare provider.
