New Concentration for Infant Acetaminophen/Tylenol

You will soon see an industry wide change in Infant acetaminophen/Tylenol packaging and labeling – the old Infant acetaminophen drops with a concentration of 80mg per 0.8 ml will be discontinued, and all new Infant acetaminophen products will be suspension with a concentration of 160 mg/5ml.   This means that infant acetaminophen products will be the same concentration as children’s acetaminophen products, and new dosing directions for infants will apply.   This transition is consistent with FDA recommendations and is designed to minimize dosing errors due to having two different concentrations of acetaminophen products.

For a while, both the old and new acetaminophen products may be on store shelves, and in your medicine cabinet.   The recommended dose in milligrams of acetaminophen per pound or kilogram remains the same, but the volume of medication on a weight or age basis will change for infants because of the change in the concentration of the infants’ formulation.

OLD concentration of infant’s acetaminophen drops:  80 mg/0.8 ml

NEW concentration of infant’s acetaminophen suspension: 160 mg/5 ml

Please note there will be no change to children’s acetaminophen/Tylenol concentration.

When determining the dose of acetaminophen/Tylenol to give your infant or child, please be sure to check the concentration of the acetaminophen product you have.  This can be found on the front of the medicine bottle – we want to be certain that during the transition period from old to new concentration of infant’s acetaminophen we are aware of the concentration of the product you have before advising what the appropriate amount of medication to be taken is.

We treat fever to make children more comfortable – take your time to check your labels, ask questions if need be, and ensure that infants older than three months and toddlers are receiving the proper dose of medication.  (Please remember any infant under three months of age with a fever should not simply receive acetaminophen/Tylenol.  In these circumstances please call us immediately for recommendations about an appropriate medical evaluation and treatment plan. Infants under three months of age should receive acetaminophen/Tylenol only if directed by a health care professional.)

Please do not hesitate to ask if you have any questions!
