Summary
Fluoroquinolones can cause both hypoglycemia and hyperglycemia, particularly in patients taking antidiabetic drugs. Glucose control may become unpredictable during therapy with fleroxacin.
What this interaction means in plain words
Fleroxacin and Rosiglitazone can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Fluoroquinolones alter pancreatic beta-cell insulin release, causing dysglycemia that adds to the effect of antidiabetic drugs.
What to do
Monitor blood glucose closely during the antibiotic course and educate the patient about hypoglycemia symptoms. Consider a non-fluoroquinolone antibiotic in patients with unstable glucose control.
