Dr. House regularly uses Vicodin in House M.D. Vicodin is a prescription combination of hydrocodone and acetaminophen, and the show presents House’s dependence on it as a major part of his character and continuing storyline.
House takes the medication to manage chronic pain caused by muscle damage in his right leg. His reliance becomes increasingly consequential: colleagues question his judgment, hospital administrators challenge his behavior, and his addiction affects friendships, diagnoses, and treatment decisions.
The series uses Vicodin not merely as a detail about pain relief but as a source of conflict. House’s intelligence and medical skill do not prevent substance dependence, and the show repeatedly explores the difference between treating pain and treating addiction.
Vicodin is sometimes incorrectly substituted with other opioid pain medicines when people summarize the character. Those drugs may appear in discussions of addiction, but Vicodin is the medication most specifically associated with House throughout the series.
