Infant Dosage Information

Ibuprofen and Acetaminophen are common OTC (over-the-counter) fever and pain reducers. Ibuprofen may be better known under the brand names Motrin and Advil. Acetaminophen is better known under the brand name Tylenol. Treating a child's fever using Ibuprofen or Acetaminophen may make your infant more comfortable, but will not make an infection get better any faster. There are many risks with children taking Tylenol and Acetaminophen, please consult your doctor about these risks, and always follow the instructions on the package and or label of the medicine.

Ibuprofen and Acetaminophen or any other medicine should only be dosed to infants under a doctor's recommendation.

If you have that recommendation, please view the charts below for dosage information. Occasionally, Pediatrician's do make a recommendation for giving children Acetaminophen or Ibuprofen, but do not provide a dosage recommendation. Once parents get to the store to buy our children the medicine, we realize that the manufacturer has not provided any dosage recommendations for children under the age of six, despite this information being available, but hard to find on the manufacturer's website. The below information has been sourced from medical organizations and provided for parents in this predicament. The information has been sourced from 2 leading infant Acetaminophen & Ibuprofen manufacturers, the Kaiser Permanente Medical Group, and public health agencies. I hope this information is helpful to you, and that you spent less time looking for it than I did. Please feel free to browse the source information in the right hand column of this website under the heading of the same name.
