Abstract Background & Objective The risk of adverse reactions necessitated the pharmacovigilance system for patient safety. Literature search documented better health literacy of patients through intervention. This investigation aims to assess the perception and the effect of an intervention on patients regarding adverse reactions caused by drugs.MethodsA pre-diagnostic and post-interventional cross-sectional investigation was designed in hospitals of Islamabad. The proportion of patients was selected based on a stratified probability technique. A prevalidated tool was used to collect the response twice through health promotion brochure with counseling was applied as an intervention.Results The findings of the study disclosed that health intervention improved health literacy among patients. Knowledge of pharmacovigilance was known by 97.9% of the patients in the interventional survey compared to a diagnostic survey in which the majority of the sampled population was not aware. The outcome of intervention on paired variables of knowledge, communication, and practice showed significant differences at the 0.05 level by using t-test statistics.ConclusionThe finding of the investigation provided evidence that patient awareness significantly improved by the health promotion model. Patient participation in the reporting of adverse reactions of drugs will complement the hospital staff reporting.
