Refractory hypoglycemia from ciprofloxacin and glyburide interaction.
Patients taking multiple medications may suffer from unpredictable and complex drug-drug interactions resulting in significant morbidity and mortality. There are few reports in the literature of hypoglycemia with concurrent administration of an oral hyperglycemic agent and a fluoroquinolone antibiotic. We present a case of a diabetic patient taking glyburide who was prescribed ciprofloxacin and developed prolonged hypoglycemia, which persisted for over 24 hours. The mechanisms by which these agents interact to produce prolonged hypoglycemia are complex and probably multifactorial. Patients stabilized on glyburide who are started on a fluoroquinolone should have their glucose levels monitored closely.
