Medication Dosing for Children

Medications like children’s acetaminophen (Tylenol), ibuprofen and diphenhydramine (Benadryl) are dosed based on your child’s weight.  To ensure you are giving the correct dose, follow the guidelines listed in the tables below.

 

Table Notes:

CAUTION: In May 2011, a move to one standard concentration of liquid acetaminophen medicine for infants and children was announced. Up until this point, there have been mainly 2 concentrations: 80mg/0.8ml (Infant Concentrated Drops) and 160mg/5ml (Children's Liquid Suspension or Syrup). During this transition period, both old and new concentrations of infant acetaminophen may be available on store shelves and in your home. Before selecting a dose, please check your infant package carefully to find the concentration. Then select the dosage according to the correct concentration and child's weight.

Alternating or Combining Acetaminophen and Ibuprofen

Combining acetaminophen and ibuprofen is generally not recommended. Combining can cause confusion, dosage errors, and poisoning. Also, it is usually not important to control a fever that closely.

If instructed by your doctor to alternate acetaminophen and ibuprofen, do it as follows:

  • Alternate doses of acetaminophen and ibuprofen every 4 hours
  • Alternate medicines for only 24 hours or less, then return to a single product
