| Summary: | Objective: Few studies are available on the association between gallstones and metformin use. The objective of the study was to determine whether metformin use is associated with gallstones.Methods: A population-based retrospective cohort study was conducted using the database of the Taiwan National Health Insurance Program. Subjects of newly diagnosed diabetes mellitus were included from 2002 to 2013. The metformin-exposure group was defined as ≥29 cumulative defined daily dose (DDD) of metformin use. The un-exposure group was defined as <29 cumulative DDD of metformin use. The major endpoint was a new diagnosis of gallstones during the follow-up period. A multivariable Cox proportional hazards regression model was used to evaluate the hazard ratio (HR) and 95% confidence interval (CI) of gallstones associated with metformin use.Results: After controlling for potential confounders, the adjusted HRs of gallstones were 1.11 (95%CI: 0.84-1.46) for subjects with metformin dosage of 29-180 cumulative DDD, and 0.57 (95%CI: 0.42-0.78) for subjects with metformin dosage >180 cumulative DDD, compared with the un-exposure group.Conclusion: Long-term use of metformin is associated with reduced risk of gallstones. |
