  • ADULT DOSAGE: 400 mg
  • FREQUENCY: Repeat every 6-8 hours as needed
  • IBUPROFEN DROPS: Ibuprofen infant drops come with a measuring syringe
  • 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.
