Purpose: Human immunodeficiency virus-infected patients do not adhere to their antiretroviral therapy (ART) due to adverse effects of drugs. The continuous monitoring of adverse drug reactions (ADRs) may ensure the safe use of drugs in patients. Hence, a retrospective analysis was carried out to assess the ADRs pattern, causality, and severity associated with various antiretroviral drug regimens in patients receiving ART. Materials and Methods: A retrospective, analytical study was carried out at ART nodal center in Sri Venkateswara Ramnarain Ruia Government General Hospital, Tirupati. Data were collected by spontaneous reporting of health-care professionals from ART centers using Suspected ADR Reporting Forms of Indian Pharmacopoeia Commission to record the ADRs occurred in the patients who underwent treatment from December 2015 to November 2016. A total of 299 ADR reports were collected during the study period. The causality and severity of the reported ADRs were assessed using suitable scales. Results: From a total of 299 ADR reports, females (63.81%) experienced higher ADRs than males (36.12%). The highest number of ADRs was reported to zidovudine/lamivudine/nevirapine (ZLN) regimen (76.92%) than tenofovir/lamivudine/efavirenz (TLE) regimen (23.07%). Cutaneous reactions were higher (34.34%) among patients receiving ZLN therapy, and drowsiness (53.62%) was the most common ADR in patients receiving TLE regimen. According to the World Health Organization causality assessment scale, most of the ADRs were possible (75.92%). On the assessment of Modified Hartwig and Siegel Severity Scale, 55.09% of ADRs were moderate. Conclusion: The study showed an increased incidence of ADRs to ART which calls for efficient pharmacovigilance systems to improve patient care and drug safety.
