Tylenol Dosage












Ibuprofen (Motrin, Advil) Dosage Table



When to Use. Treatment of fever and pain.

Table Notes:

  • Age Limits. Don't use under 6 months of age unless told by your child's doctor. Reason: safety not established and not approved by FDA. If under 6 years, 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 below the correct weight for the dose based on the product you have.

  • 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.

  • Infant Drops. Ibuprofen infant drops come with a syringe.

  • How Often. Repeat every 6-8 hours as needed.

  • Adult Dose. 400 mg

  • Brand Names. Motrin, Advil, generic ibuprofen
