Dosage Infant Tylenol Calculator

The AAP chart covers infants from 6 lb; the OTC label declines to dose under 24 lb and this calculator declines with it.
Dose by weight whenever the weight is known; the age bands are only a fallback.
Used only to flag a mismatch with the weight band and to warn below two years.

AAP / HealthyChildren.org acetaminophen dosing chart
Worked out from Infants' TYLENOL (acetaminophen) oral suspension - FDA OTC Drug Facts label, DailyMed and 3 other sources.
Check the bottle: this dose assumes 160 mg in 5 mL (32 mg/mL). A different concentration means a different volume.
Use only the dosing syringe or cup that came with the product.
Never give another product containing acetaminophen at the same time, including combination cough and cold medicines.
The AAP chart states plainly: acetaminophen should not be given to a child under two years of age without the guidance of a doctor. Call your doctor before giving this dose.
This is a lookup of a published dosing chart, not medical advice. It does not replace your child's doctor, pharmacist, or the Drug Facts label and dosing device on the pack you actually have. Check the concentration printed on your bottle before giving any dose, never combine two products containing acetaminophen, and call a doctor or poison centre immediately if you think too much has been given.

How this is worked out

4 steps
  1. Weight 16 lb (7.26 kg) falls in the "12 to 17 lb (5 to 7 kg)" band of the AAP / HealthyChildren.org acetaminophen dosing chart.
  2. That row gives 2.5 mL of Infants' acetaminophen oral suspension, 160 mg / 5 mL.
  3. Strength 160 mg in 5 mL (32 mg/mL), so each dose is 2.5 x 32 = 80 mg of acetaminophen.
  4. Repeat no sooner than every 4 hours and give no more than 5 doses in 24 hours: at most 400 mg in a day.
