Table Notes:

  • DOSE. Find the child's  age  in the first column. Look for correct dosing based on age and product form.
  • MEASURE the DOSE. Syringes and droppers are more accurate than teaspoons. If possible, use the syringe or dropper that comes with the medicine.  If not, you can get a med syringe at drug stores. 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.  
  • ADULT DOSE. 10 mg
  • HOW OFTEN. Repeat every 24 hours as needed.
