Hydrocodone is in a group of drugs called narcotic pain relievers. Acetaminophen is a less potent pain reliever that increases the effects of hydrocodone.

Acetaminophen and hydrocodone may also be used for purposes other than those listed in this medication guide.
Hydrocodone is a strong opiate painkiller with highly addictive properties. Acetaminophen is a much milder non-steroidal pain reliever. Vicodin may contain 5 milligrams of hydrocodone and 325 milligrams of acetaminophen or as much as 10 milligrams of hydrocodone and 660 milligrams of acetaminophen. While hydrocodone is the addictive component of this pill, acetaminophen has resulted in serious liver damage at high dosages.
