Using Weight to Determine Infant Motrin Dosage: A Guide for Parents

Introduction

As a parent, it is important to know how to properly administer medication to your infant. One of the most common medications given to infants is Motrin, an over-the-counter pain reliever and fever reducer. It is important to know how to measure out the proper dosage of Motrin for infants, as giving too much can be dangerous. In this article, we will discuss how to use weight to determine infant Motrin dosage.

What is Motrin?

Motrin is the brand name for ibuprofen, an over-the-counter pain reliever and fever reducer. It is used to reduce pain and fever in infants, children, and adults. Ibuprofen works by blocking the production of certain hormones in the body that cause inflammation and pain. It is important to note that ibuprofen is not recommended for use in infants under 6 months of age.

How to Measure Infant Motrin Dosage

When using Motrin to treat pain and fever in infants, it is important to measure the correct dosage. The dosage of Motrin for infants is based on their weight, not their age. The following chart can be used to determine the correct dosage of Motrin for infants:

Administration of Infant Motrin

Once you have determined the correct dosage of Motrin for your infant, it is important to know how to administer it properly. Motrin can be given either as a liquid suspension or as a chewable tablet.
