RESUMO
Objectives: To identify the adverse drug reactions (ADRs) to antiretroviral therapy (ART) and to assess their impact on treatment compliance in patients with HIV/AIDS. Materials and Methods: Two hundred and thirty-five (235) AIDS patients who received ART were monitored for ADRs over a period of 6 months. The incidence and nature of ADRs occurring with different ART regimens were recorded. We also assessed the severity, causality as well as the impact of ADRs on the patients' compliance. Results: Of 235 patients receiving ART, 90.6% patients experienced ADRs. A total of 618 ADRs involving various systems were observed. A majority were related to gastrointestinal (42.39%) and central nervous (25.57%) system. 23.1% ADRs were severe in intensity. Severe ADRs occurred in 41 out of 235 (17.4%) patients necessitating drug withdrawal. A majority of the patients (87.8%) who complained of severe ADRs received combination of stavudine, lamivudine and nevirapine. Causality assessment revealed 6.63% ADRs were probable and 93.3% ADRs were possible. Non-compliance due to ADRs was observed in 28.9% patients. Conclusions: Myriad ADRs are associated with ART which leads to poor patient compliance. With the increasing access to ART in India, it is prudent that antiretroviral drugs are used judicially with regular monitoring of ADRs.
