Antiretroviral therapy (ART) is associated with long- and short-term adverse reactions (ARs). The objectives of this book are to describe patient demographics, types of AR according to treatment regimen, organ and system affected, severity, causality category, reporting health professional, reporting health facility, and timing of reporting of suspected ARR to antiretroviral (ARV) drugs to the National Centre for Pharmacovigilance (CNFV). A retrospective review was conducted of the ARV ARV suspicion notification forms reported to the CNFV from January 2007 to December 2010. We included 1972 notifications in which 2502 ARVs were identified, 1160 (58.82%) were male, ranging in age from 1 to 96 years (median age 37 years). Antiretroviral treatment (ART) regimens classified as suspicious were 29, the most reported being AZT+3TC+NVP, with 839(42.55%) notifications.
