Nevirapine (NVP) is a nonnucleoside reverse transcriptase inhibitor widely used in combination with other antiretroviral agents for the treatment of human immunodeficiency virus disease. To establish its safety profile, we conducted a review of data from prospective US and international clinical trials involving a total of 906 adult patients and 468 pediatric patients treated with NVP. Drug-related adverse events were similar in adults and children, with rash and nausea most frequently reported in adults and rash and granulocytopenia most frequently reported in children. A separate analysis of rash based on data from adult patients in controlled trials demonstrated a 16% rate of NVP-attributable rash in these patients. Of patients with NVP-associated rash, 65% developed rash within the first 6 weeks of therapy, and it has been shown that a lower lead-in dose (200 mg/d vs the standard 400 mg/d) for the first 2 weeks of NVP treatment reduces the frequency of drug-associated rash. Serious rash (Stevens-Johnson syndrome [SJS] or SJS/toxic epidermal necrolysis transition syndrome) occurred with an incidence of 0.3% and clinical hepatitis with an incidence of 1.0% among NVP-treated patients in clinical trials. Adverse event data from long-term clinical trials demonstrated a lower incidence of NVP-related adverse events than in short-term trials of NVP therapy. An analysis of abnormal laboratory findings using thresholds similar to those found in the prescribing information for other commonly used antiretroviral agents and data from controlled trials in adults showed that the most frequently observed laboratory abnormalities were elevations in liver function test results. Approximately 50,000 patients in the United States had been treated with marketed NVP at the time of writing, and postmarketing surveillance has supported the overall safety profile observed in clinical trials. NVP has been shown to be well tolerated in both adult and pediatric patients.

Nevirapine, a nonnucleoside reverse transcriptase inhibitor used as part of combination antiretroviral therapy, can cause mild elevations in transaminase levels. Severe elevations in transaminase levels related to the use of nevirapine developed in 4 patients. Data on these patients were extracted via chart review, and a review of the literature was also completed. Nevirapine-induced hepatitis occurred shortly after drug initiation in patients with and without preexisting liver disease. Significant elevations in liver enzyme levels occurred but resolved promptly in most with discontinuation of the nevirapine. Close monitoring of liver enzyme levels in the early period after starting nevirapine is essential.

Nevirapine induced hepatotoxicity is known but fatality is rare. We report a case of a young individual who developed nevirapine (NVP) induced fatal hepatitis without apparent risk factors or preceding rash. Exacerbation of underlying silent chronic liver dysfunction possibly contributed to the fatal outcome. This case stresses the need for careful evaluation, regular monitoring and prompt omission of drug on suspicion of hepatotoxicity.

Nevirapine is a non-nucleoside reverse transcriptase inhibitor, widely used in combination with other antiretroviral agents for treatment of HIV infection. Steven Johnson syndrome (SJS) is the major toxicity of nevirapine. We describe here four cases of SJS in HIV seropositive patients following nevirapine therapy. In all four cases cutaneous hypersensitivity reaction was seen with extreme oral lesions, three patients presented clinically with elevated liver enzymes and hepatitis, and two patients had ocular involvement.
