Infant Tylenol Side Effects

While infant Tylenol side effects are not likely to occur (unless the drug is taken inappropriately), be sure to seek medical attention immediately if your child develops any problems. Side effects that may occur after taking too much infant Tylenol include sweating, diarrhea, appetite loss, and yellowing of the eyes or skin.

 

Infant Tylenol Side Effects: An Introduction

As with any medicine, side effects are possible with Concentrated Tylenol® Infants' Drops (infant acetaminophen); however, not everyone who takes the medication will experience side effects. In fact, most infants tolerate it quite well. In most cases, side effects occur when too much infant Tylenol is given.
 
The official name of this product is "Concentrated Tylenol Infants' Drops." However, this article uses the name interchangeably with "infant Tylenol," since this is how the drug is commonly referred to.
 
(This article covers many, but not all, of the possible side effects with infant Tylenol. Your child's healthcare provider can discuss a more complete list of infant Tylenol side effects with you.)
 

Serious Side Effects of Infant Tylenol

Infant Tylenol is a non-prescription medication. With prescription medications, the manufacturers must provide "prescribing information" that includes detailed information about side effects. However, such information is not available for most non-prescription medications, including infant Tylenol.
 
Most of the information about infant Tylenol side effects comes from information about Tylenol overdose. Therefore, these serious side effects are not very common (unless, of course, you give your infant too much Tylenol). These side effects include, but are not limited to:
 
  • Sweating
  • Diarrhea
  • Irritability
  • Nausea and vomiting
  • Appetite loss
  • Abdominal pain, especially near the liver (the upper right part of the abdomen)
  • Yellow eyes or skin
  • Liver failure
  • Kidney failure
  • Heart problems
  • Coma.
     
Rarely, ulcers or bleeding in the digestive tract can occur with infant Tylenol, although it is much less common for infant Tylenol than for other non-prescription pain relievers.
 
Most infants do not experience any infant Tylenol side effects, except when it is taken inappropriately.
