In House M.D., which fictional drug addiction is central to Dr. House’s character?

In House M.D., Vicodin addiction is central to Dr. House’s character.

House takes Vicodin, an opioid pain medication containing hydrocodone and acetaminophen, to manage chronic pain caused by an infarction in his right quadriceps muscle. The injury left him with lasting leg damage and a limp. His reliance on the drug develops into dependence and addiction, creating an ongoing medical, ethical, and personal conflict.

The series depicts repeated attempts to control or stop House’s use, including rehabilitation, withdrawal, and relapses. His addiction affects his judgment, relationships, employment, and interactions with hospital leadership. It is not merely a character detail: it is one of the show’s continuing story engines.

Vicodin is sometimes confused with medications House uses in individual episodes or with the name of his underlying injury. Vicodin is the pain medication associated with his addiction; the quadriceps infarction is the cause of his chronic pain, not the addiction itself.
