Summary
Fluoroquinolones can cause both severe hypoglycemia and hyperglycemia, and the risk is higher in diabetic patients treated with insulin or oral agents. Serious and occasionally fatal cases of hypoglycemia have been reported, particularly in elderly and renally impaired patients.
What this interaction means in plain words
Insulin neutral human and Levofloxacin 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.
Insulin neutral human belongs to Endocrine; Levofloxacin belongs to Anti Bacterial.
Why it happens
Fluoroquinolones alter pancreatic beta-cell insulin release, producing dysglycemia that adds to the effect of exogenous insulin.
What to do
Monitor blood glucose closely during levofloxacin therapy and for several days after, and adjust insulin as needed. Stop the antibiotic and treat promptly if hypoglycemia occurs.
