Drug-induced vasculitis is defined as any type of inflammatory vascular disorder caused by the administration of a pharmacologic agent. The clinical presentation of drug-induced vasculitis ranges from isolated skin or central nervous system disease to multiorgan involvement. Drugs from almost every pharmaceutical class and category have been cited as causal agents for drug-induced vasculitis, including antimicrobials, immunosuppressive and chemotherapeutic agents, drugs of abuse, psychotropic medications and many others. The level of evidence establishing causality of specific agents with vasculitis varies greatly. Treatment of drug-induced vasculitis includes the withdrawal of the putative causative agent and consideration, in selected cases, of the use of glucocorticoids and/or immunosuppressive drugs. This chapter reviews the approach to diagnosis, causative agents, clinical features, laboratory findings, histopathology and treatment of drug-induced vasculitis.
