Infant Tylenol

Infant Tylenol is used for reducing fever and relieving minor aches and pains in infants under the age of three. Generally, it is best to give your child the medication before feeding to help prevent spitting up the medication. Serious side effects that may occur include allergic reaction, liver damage, and ulcers or bleeding in the digestive tract. However, most infants tolerate the medication quite well.

What Is Infant Tylenol?

Tylenol® (acetaminophen) is a non-prescription pain reliever and fever reducer. Tylenol comes in many different strengths and forms. For infants under the age of three, it is available as Infants' Tylenol (infant acetaminophen).

How Does Infant Tylenol Work?

Even though Tylenol has been around for quite a while, it is not fully understood exactly how it works. It is known that Tylenol works differently from any other non-prescription medication. Most other non-prescription pain relievers or fever reducers are nonsteroidal anti-inflammatory drugs (NSAIDS). Both NSAIDS and Tylenol block the body's production of prostaglandins (naturally occurring chemicals that cause inflammation and fever).
 
However, while NSAIDS block prostaglandin production throughout the body, Tylenol appears to do so just in the central nervous system (the brain and spinal cord). Tylenol may also work by blocking pain signals from nerves (or preventing such signals from forming).
 
Because Tylenol is not related to aspirin, it can be safely used by infants with chickenpox. Also, many infants who are sensitive or allergic to aspirin can safely take Tylenol.
