Infant Acetomenophin (Tylenol) Dosage Chart

How much Acetomenophin (Tylenol) can I give my baby?

Even after I hear it from the pediatrician about five times during the doctor’s appointment, I come home and wonder if I heard it correctly, if I wrote it down correctly and if I saved it correctly on my phone.

Once I found this handy chart, life became much easier. I verified it with my son’s pediatrician and she also gave me the formula they use to calculate the same, which perfectly matches this chart !


Download this handy chart and put it up on your refrigerator or medicine cabinet for quick reference. Please make sure you are using the chart BY WEIGHT* and not by age.

If you don’t know the exact weight of your baby, use this chart from WHO and CDC to get an APPROXIMATE weight range for your kid. Remember, it is always important to know the EXACT dosage of medication to give your child, so try and get the weight as soon as you can.

To know when a fever is dangerous in a baby, see this post.

When to Use Tylenol -Indications: Treatment of fever and pain.

Table Notes:

  • CAUTION: In May, 2011, a move to one standard concentration (160 mg/5 ml) of liquid acetaminophen medicine for infants and children was announced. Up until that time, there were mainly 2 concentrations: 80 mg/0.8 ml (Infant Concentrated Drops) and 160 mg/5 ml (Children’s Liquid Suspension or Syrup). Old concentrations (80mg/0.8 ml) of infant acetaminophen may still be available in some homes. Therefore, if it is an older product, please have the caller confirm the correct concentration of infant acetaminophen.
  • AGE LIMIT: Don’t use under 12 weeks of age (Reason: fever during the first 12 weeks of life needs to be documented in a medical setting and if present, your infant needs a complete evaluation.) EXCEPTION: Fever from immunization if child is 8 weeks of age or older. Avoid multi-ingredient products in children under 6 years of age. (Reason: FDA recommendations 1/2008).
  • DOSAGE: Determine by finding child’s weight in the top row of the dosage table
  • MEASURING the DOSAGE: Syringes and droppers are more accurate than teaspoons. If possible, use the syringe or dropper that comes with the medicine. If not, medicine syringes are available at pharmacies. If you use a teaspoon, it should be a measuring spoon. Regular spoons are not reliable. Also, remember that 1 level teaspoon equals 5 ml and that ½ teaspoon equals 2.5 ml.
  • FREQUENCY: Repeat every 4-6 hours as needed. Don’t give more than 5 times a day.
  • ADULT DOSAGE: 650 mg MAXIMUM: 3,000 mg in a 24-hour period.
  • BRAND NAMES: Tylenol, Feverall (suppositories), generic acetaminophen
  • MELTAWAYS: Dissolvable tabs that come in 80 mg and 160 mg (jr. strength)
  • SUPPOSITORIES: Acetaminophen also comes in 80, 120, 325 and 650 mg suppositories (the rectal dose is the same as the dosage given by mouth).
  • EXTENDED-RELEASE: Avoid 650 mg oral products in children (Reason: they are every 8 hour extended-release)
