Purpose: The study evaluated the knowledge and attitudes of HIV-infected patients on ART regarding ADRs following routine patient counseling and education in selected hospitals in Nigeria. Materials and Methods: From 36,459 HIV-infected patients on ART in the 36 selected hospitals, a study-specific instrument was administered to 3,650 patients in a cross-sectional study. Patients were provided counseling and education on ADRs before and after commencing ART. Factor analysis was performed using principal components extraction. Item score means above midpoint (3.7) on a 5-point scale were regarded as positive attitudes and below as negative attitudes. A chi-square test was used for inferential statistics; P<0.05 was used to determine statistical significance. Results: The mean questionnaire return rate was 47.5%. Data from 2329 (63.8%) participants were analyzed, 63.1% females and 34.4% aged 25-34 years old. A total of 80.1% participants accepted to have been counseled on ADRs; 65.8% knew that all medicines cause some kind of adverse effects; 55.1% knew the adverse effects of their medicines; 60.8% knew what to do when they suspect ADRs and it included mainly reporting to the healthcare provider (88.1%). However, only 31.9% had experienced ADRs previously. The knowledge of ADRs was associated with gender and educational and employment status of the patients (P<0.05). A total of 95.6% reported self-efficacy to ART. Majority of the rated attitude score means were >3.7 which denotes positive attitudes to ADRs. Three extracted factors accounted for 73.1% of cumulative variability. All attitude items had very significant loadings of ≥0.5. Conclusion: Overall, participants reported good knowledge and positive attitudes to adverse effects of their medicines compared to what was reported previously. The patient counseling and education on drug therapy provided to patients may have contributed to these findings and are highly recommended.
