Vicodin is a prescription medication that combines two active ingredients: hydrocodone and acetaminophen. Hydrocodone is an opioid analgesic, while acetaminophen is a non-opioid pain reliever. Vicodin is used primarily for the relief of moderate to severe pain. It is manufactured by several pharmaceutical companies and is classified as a Schedule II controlled substance in the United States due to its potential for abuse and dependence.
