Metformin as a Rare Cause of Drug-Induced Liver Injury, a Case Report and Literature Review
Abstract
Metformin is an oral hypoglycemic agent that is commonly used in the treatment of type 2 diabetes mellitus. Although metformin-associated gastrointestinal upset and metabolic acidosis is widely recognized side effect of this drug, metformin-induced liver injury has been rarely reported in the literature. In most cases reported, metformin-induced liver injury was associated with concomitant intake of other hepatotoxic drugs. Here, we report a case of a 70-year-old white woman who suffered metformin-induced liver injury 5 weeks after starting on this medication, and she was not on any other hepatotoxic agent. With increasing prescription of metformin, this case deserves particular attention for this rare but important side effect.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
