Hydrocodone is a prescription opioid medication prescribed as a suppressant to cough and a medication for pain. Hydrocodone is the most frequently prescribed opioid in the United States, with over 83.6 million prescriptions given in 2017 for hydrocodone-containing products. There are brand names and generic hydrocodone products marketed in the U.S. Many people may be familiar with hydrocodone product brand names: Vicodin, Norco, Vicoprofen and Hycodan. The hydrocodone and acetaminophen are the most commonly prescribed combination. Hydrocodone is misused because of the euphoric "high" the user experiences because of its opioid effects.
