Table Notes:

  • AGE LIMIT: Don't use under 4 years of age.
    • Reason 1: Not approved by FDA because dosage not studied in this age range
    • Reason 2: Risk of dosage error causing high blood pressure
  • CAUTION: Never give 2 cough or cold medicines at the same time. (Reason: May share an ingredient and cause poisoning). Avoid multi-ingredient products in children under 6 years of age (AAP recommendations 10/2008)
  • AVAILABILITY: Pseudoephedrine products are found behind the counter of pharmacies in response to legislation enacted in 2006. Ask a pharmacist for assistance in obtaining these medications.
  • 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 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.
  • ADULT DOSAGE: 60 mg maximum
  • FREQUENCY: Repeat every 6 hours as needed
