Indications: Treatment of fever and pain.

Table Notes:

  • AGE LIMIT: Don’t use under 12 weeks of age unless directed by child’s doctor. (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 starting within 24 hours of 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
  • BRAND NAMES: Tylenol, Feverall (suppositories), generic acetaminophen
  • FREQUENCY: Repeat every 4-6 hours as needed. Don’t give more than 5 times a day.
  • ADULT DOSAGE: 650 mg
  • 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)
  • MEASURING the DOSAGE: Syringes and droppers are more accurate than teaspoons. If possible, use the syringe or dropper that comes with the medication. 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.
