Sepsis Mimicker in an Human Immunodeficiency Virus-Infected Patient.

A 22-year-old human immunodeficiency virus-infected male presented with fever, rash, hypotension, and renal insufficiency 18 days following initiation of therapy with an efavirenz-based antiretroviral regimen. Although rash is a common side effect of efavirenz, severe hypersensitivity reactions are rare. Systemic symptoms can include hepatic toxicity and pneumonitis, and in one instance death. Corticosteroids are the mainstay of treatment.
