Summary
Fluoroquinolones can cause both hypoglycemia and hyperglycemia in patients treated with insulin. Severe hypoglycemia has been reported, particularly in older adults and those with renal impairment.
What this interaction means in plain words
Insulin regular human and Ofloxacin 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 appear to alter pancreatic beta-cell insulin release, producing unpredictable dysglycemia that adds to the effect of exogenous insulin.
What to do
Monitor blood glucose closely during and shortly after ofloxacin therapy and teach the patient to recognize hypoglycemia symptoms. Adjust the insulin dose as needed and stop the quinolone if significant dysglycemia occurs.
