The human immunodeficiency virus (HIV) type-1 non-nucleoside reverse transcriptase inhibitor, efavirenz, is widely used to treat HIV-1 infection. Efavirenz is predominantly metabolized into inactive metabolites by CYP2B6, and patients with certain CYP2B6 genetic variants may be at increased risk for adverse effects, particularly central nervous system toxicity and treatment discontinuation. We summarize the evidence from the literature and provide therapeutic recommendations for efavirenz prescribing based on CYP2B6 genotypes. This article is protected by copyright. All rights reserved.
