Important:

  • Age Limits: For allergies, don't use under 2 years of age unless otherwise directed.  It should not be given if under 6 months old.
  • Reason: It is not FDA approved at younger ages. For colds, not advised at any age, because there are no proven benefits.

Instructions:

  • Dose: Find the child's age in the top row of the dose table. Look below the correct age for the dose based on the product you have.
  • Measure the Dose: Always use syringes and droppers for liquid medication (teaspoons vary too much, and could lead to incorrect dosing). If possible, use the syringe or dropper that comes with the medicine. If not, you can get a med syringe at a drug store. If you use a teaspoon, it should be a measuring spoon. Reason: regular spoons are not reliable. Keep in mind 1 level teaspoon equals 5 mL and that ½ teaspoon equals 2.5 mL.
