How is Tylenol different from other brands of pain reliever?
Acetaminophen is the active ingredient in Regular Strength Tylenol. Tylenol products do not contain aspirin, ibuprofen, naproxen, or ketoprofen. One of the advantages of using Tylenol is that it is unlikely to cause the stomach irritation often associated with aspirin, naproxen sodium, ketoprofen and even ibuprofen, the active ingredients found in some other nonprescription pain relievers. The medicine in Tylenol is also less likely to interact with other medications you may be taking. Always read and follow labeled directions. Do not use Tylenol with other acetaminophen-containing products, unless directed by your doctor.
