Our case illustrates multiple predisposing and precipitating factors occurring simultaneously that have been previously implicated individually in the development of neuropsychiatric complications with efavirenz (and other HIV treatments in general). We suggest that patient\u2019s commenced on antiretroviral medication should have a screening process for pre-existing mental and medical health problems as well as psychosocial risk factors that might put a patient at risk. In addition with advances in pharmacogenomics we advocate future cytochrome P450 gene variant testing coupled with routine efavirenz plasma concentration monitoring to help ensure maximum treatment benefit and minimal risk of side effects.<\/jats:p>","DOI":"10.1136\/bcr.07.2009.2061","type":"journal-article","created":{"date-parts":[[2009,11,27]],"date-time":"2009-11-27T23:56:43Z","timestamp":1259366203000},"page":"bcr0720092061","source":"Crossref","is-referenced-by-count":2,"title":["Neuropsychiatric sequelae in an efavirenz treated patient with hepatitis B: Table 1"],"prefix":"10.1136","volume":"2009","author":[{"given":"Emma","family":"Salter","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anish S","family":"Patel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2009,11,26]]},"reference":[{"key":"2025042508200397000_2009.nov26_1.bcr0720092061.1","doi-asserted-by":"publisher","DOI":"10.1097\/00002030-200302140-00026"},{"key":"2025042508200397000_2009.nov26_1.bcr0720092061.2","doi-asserted-by":"publisher","DOI":"10.1086\/427031"},{"key":"2025042508200397000_2009.nov26_1.bcr0720092061.3","first-page":"2391","article-title":"Pharmacogenetics of efavirenz and central nervous system side effects: an adult AIDS Clinical Trials Group study","volume":"18","author":"Haas","year":"2004","journal-title":"AIDS"},{"key":"2025042508200397000_2009.nov26_1.bcr0720092061.4","doi-asserted-by":"publisher","DOI":"10.1086\/522764"},{"key":"2025042508200397000_2009.nov26_1.bcr0720092061.5","doi-asserted-by":"publisher","DOI":"10.1097\/00002030-200109280-00033"},{"key":"2025042508200397000_2009.nov26_1.bcr0720092061.6","doi-asserted-by":"publisher","DOI":"10.1086\/321828"},{"key":"2025042508200397000_2009.nov26_1.bcr0720092061.7","doi-asserted-by":"publisher","DOI":"10.1592\/phco.22.11.930.33624"},{"key":"2025042508200397000_2009.nov26_1.bcr0720092061.8","doi-asserted-by":"publisher","DOI":"10.1046\/j.1468-1293.2003.00160.x"},{"key":"2025042508200397000_2009.nov26_1.bcr0720092061.9","unstructured":"Marwaha A .
