Alternatives for Infant/Children’s Liquid Pain Medication

The ongoing shortage of infant and children’s pain and fever medications has left many parents seeking alternatives.

Acetaminophen (Tylenol) and Ibuprofen (Advil, Motrin) are dosed based on a child’s weight in kilograms (kg).

It is safe to give an adult formulation of these medicines to infants and children if it is dosed correctly.

The following charts can serve as a dosing guide. Speak with your pharmacist for tips/tools regarding crushing and preparing these pills for your child.
