Acetaminophen, the active ingredient in TYLENOL* products, relieves mild to moderate pain by elevating your body's overall pain threshold and works to lower your fever by helping your body eliminate excess heat.

Acetaminophen has been widely used as a pain reliever since the 1950s and is suitable for adults and children. TYLENOL* is not likely to cause stomach irritation or interact with other medications you may be taking. You should not normally take acetaminophen for a period longer than 5 days except on the advice of your doctor.
