Important Update: Dosing and Concentration Changes

Dosing and Concentration Changes for OTC Infants’ Acetaminophen Products

Companies are changing the concentration of their medications for infants, and there are new dosing directions for these products.

What you should know:

There may be a time when both the old and new concentrations of infants’ acetaminophen products are in stores and also in homes.

For children under 2 years of age, no dose is provided on the OTC label — caregivers are instructed to call their doctor for dosing instructions.

What you can do:

  1. Clarify the concentration of infants’ acetaminophen product you are using.
  2. Identify the product concentration and dose for your child’s weight/age from the appropriate
    chart below.
