Background: Non-nucleoside reverse transcriptase inhibitor (NNRTI)-based antiretroviral therapy (ART) is associated with neuropsychiatric toxicity. Little is known about the risk of short- and long-term neuropsychiatric toxicity in sub-Saharan Africa, where NNRTIs are widely used in first-line combination ART. This observational study assessed the risk of neuropsychiatric toxicity in Ghanaian patients starting first-line ART between 2004 and 2010 at a single centre. Methods: In this retrospective observational study, frequencies of documented neuropsychiatric toxicity events were assessed and time to events calculated using a Kaplan–Meier analysis. Associations of neuropsychiatric toxicity with specific NNRTIs and other explanatory variables were examined using Cox proportional hazards modelling. Results: Of 3999 patients initiating NNRTI-based ART, who were followed for a median of 30 (0.25–90) months (11,237 person years), 218 (5.5%) reported symptoms of neuropsychiatric toxicity at a rate of 21.4 events per 1000 person-years (95% CI, 18.8–24.2/1000 py). Events were more common with efavirenz than nevirapine (7.6% versus 2.4%), were usually reported within the first 2 months of ART initiation and persisted up to 84 months in a few patients. The most commonly reported neuropsychiatric adverse drug reactions were insomnia (50%), headaches (8%), dizziness (7%) and abnormal dreams (6%). The factors independently associated with neuropsychiatric toxicity were BMI
