Introduction. Omeprazole is a widely used drug; in most cases, it is effective and safe. However, studies have found omeprazole to be the drug most frequently related to hospital admissions due to adverse drug reactions (ADRs). The ADRs could have occurred as a result of abuse or irrational prescribing of omeprazole. Despite that possibility, the risks and benefits of prophylactic omeprazole considering the approved and off-label uses and the potential consequences for patient safety have not been assessed. Objective. To identify and assess the risk of adverse drug events and the benefit provided by the effective use of prophylactic omeprazole in hospitalized patients. Methods. This observational cohort study was conducted from August to October 2013 and December 2013 to May 2014 at the Américo Brasiliense State Hospital. The inpatients were classified into three groups: a) approved use of prophylactic omeprazole b) off-label use of prophylactic omeprazole, and c) not using omeprazole. Patients who used no prophylactic omeprazole were excluded. The patients were monitored daily with the aid of a pre-established research protocol. Data were tabulated according to drug effectiveness or ineffectiveness and presence of adverse events in the three groups. Results. A total of 427 hospitalized patients were monitored in the study. Of these, 136 patients were exposed to prophylactic omeprazole used off-label and 52 exposed to on-label use of prophylactic omeprazole. Two cases of suspected ineffectiveness and 14 adverse events were recorded. There was a significant difference in serum creatinine and urea for patients using on-label prophylactic omeprazole. Conclusion. There are twice as many patients using off-label prophylactic omeprazole as patients using it for approved indications. There was no association of prophylactic omeprazole with risk factors, but there was a significant difference in the increase in serum creatinine and urea for ...
