Gregory House frequently misuses Vicodin in House M.D.
Vicodin is a prescription painkiller combining hydrocodone and paracetamol, also called acetaminophen. In the series, House takes it to manage chronic leg pain caused by an infarction in his quadriceps muscle. His dependence becomes a continuing medical, ethical, and personal problem.
The drug is not simply a character accessory. House’s use affects his judgment, employment, relationships, and treatment decisions, and several storylines focus on attempts to stop, conceal, or control his dependence. The show repeatedly depicts the conflict between House’s extraordinary diagnostic ability and the risks created by his addiction.
Vicodin is a brand name, so it is sometimes confused with hydrocodone itself or with other prescription opioids. In the United States, the original formulation combined hydrocodone with acetaminophen. House’s medication use is fictionalized for drama, but the dependence and withdrawal themes are grounded in real clinical concerns.
