OBJECTIVE: To assess the association between over-the-counter analgesic (OTCA) use and hospitalization for liver-associated events in cirrhotic patients. MATERIAL AND METHODS: Ninety adult cirrhotics admitted with liver-associated events and 126 non-hospitalized cirrhotic controls were enrolled prospectively into a case-control study. Standardized questionnaires were used to obtain predictor variables, including detailed 30-day OTCA use. Data were analyzed via logistic regression. RESULTS: Hepatitis C (43%), alcohol (34%), and cryptogenic (13%) were the most common etiologies of cirrhosis. OTCA use was similar between cases and controls in the 30 days prior to enrollment (34% vs. 44%; odds ratio, OR = 0.66, 95% confidence interval, CI = 0.37-1.16, p = 0.148). Adjusted analyses also found no significant association between OTCA use and hospitalization for liver-associated events (OR = 0.73, 95% CI = 0.38-1.38, p = 0.330). Furosemide (p = 0.001), lactulose (p = 0.026), and number of prior liver-associated events (p = 0.002) were positively associated with hospitalization, while propranolol showed an inverse association (p = 0.008). CONCLUSION: Our data suggest that non-excessive OTCA use is not significantly associated with hospitalization for liver-associated events.
