Tylenol has been getting a bad rap lately for the destructive side effects it causes. If you take painkillers you may be taking it under a different name. Acetaminophen commonly is sold in the US under the brand name Tylenol. This pain reliever is derived from coal tar. The drug name is commonly mis-spelled as acetominophen.
