In House M.D., what fictional drug addiction most often affects Dr. House?

Dr. House is most often affected by Vicodin addiction in House M.D.

Vicodin is a prescription painkiller combining hydrocodone and acetaminophen. House uses it to manage chronic leg pain resulting from a past vascular injury, but the medication becomes a serious dependency and a recurring source of conflict throughout the series.

The storyline is not simply a visual shorthand for House’s personality. His drug use affects his judgment, relationships, employment, and medical decisions. At different points, he attempts to stop using Vicodin, experiences withdrawal, and faces consequences from colleagues and hospital authorities.

Viewers sometimes substitute other opioid names because several prescription pain medicines appear in medical dramas. House’s signature medication, however, is Vicodin. The fictional character’s dependence is one of the show’s central long-running conflicts and is closely connected to his pain, isolation, and resistance to authority.
