Summary
Fluoroquinolones can produce hypoglycemia or hyperglycemia in diabetic patients. Metformin alone seldom causes hypoglycemia, but glucose control may become unstable during the antibiotic course.
What this interaction means in plain words
Metformin and Ofloxacin have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Metformin belongs to Endocrine; Ofloxacin belongs to Anti Bacterial.
Why it happens
Fluoroquinolones alter insulin secretion and glucose handling, which may change glycemic control.
What to do
Monitor blood glucose during the antibiotic course and report symptoms of dysglycemia. No routine dose change is needed.

- Is there anything I should notice while taking both?
