Summary

This early-phase study tested whether a gel made from acetaminophen (the active ingredient in Tylenol) can relieve itching. Seventeen healthy adults received different strengths of the gel on their skin, then had itch triggered by two different methods. Researchers measured how intense the itch felt to see if the gel worked better than a placebo.
