How long does it take for tylenol (acetaminophen) to wear off?
A doctor has provided 1 answer
4 - 6 hours average: The half life is about 4 - 6 hours and that is the recommended interval between doses as it begins to wear off during that interval. Body size, presence of food and metabolism can change this some.
