When was Tylenol first invented?

Tylenol (acetaminophen) was first developed in the early 20th century. Acetaminophen was first synthesized in 1877 by Harmon Northrop Morse, a U.S. chemist.[1]

When did Tylenol become a marketed product?

Although acetaminophen was identified in the late 1800s, Tylenol as a branded pain reliever and fever reducer was launched later. McNeil Laboratories introduced Tylenol in the United States in 1955 as a prescription product, and it became widely used as an over-the-counter medicine after that.[2]

Why the timing matters (acetaminophen vs. Tylenol)

The drug’s chemical discovery (acetaminophen in 1877) happened decades before Tylenol was packaged and sold as a specific brand under McNeil Laboratories.[1][2]
