Table Notes

  • Age Limits. Don't use under 12 weeks of age unless told by child's doctor.

    Reason: fever in the first 12 weeks of life needs to be seen now. If present, your baby needs a medical exam now.

    Exception: Fever starting within 24 hours of vaccines if child is 8 weeks of age or older. If under 6 years old, don't give products with more than one ingredient in them (FDA recommendation 2008).

  • Dose. Find the child's weight in the top row of the dose table. Look for the correct weight for the dose based on the product you have.

  • Measure the Dose. Syringes and droppers are better to use than teaspoons. 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 that 1 level teaspoon equals 5 mL and that ½ teaspoon equals 2.5 mL.
