Metabolic and hepatobiliary side effects of antiretroviral therapy (ART).

Although antiretroviral therapy (ART) for human immunodeficiency virus (HIV) has been in use since 1987, the initiation of highly active ART has produced an increase in adverse drug reactions. This is a new challenge as many of the adverse drug reactions attributable to ART may be indistinguishable from non-drug-related illnesses. The emergency physician must be aware of the potential complications of ART as affected patients may present with nonspecific symptoms. The focus of this article is the metabolic and hepatobiliary adverse effects of ART.
