Summary
Oral ciprofloxacin chelates polyvalent cations such as iron in the gut, markedly reducing absorption and risking antibiotic treatment failure. Iron dextran is given parenterally, so this chelation does not occur with the injectable form.
What this interaction means in plain words
Ciprofloxacin and Iron dextran complex have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Chelation of ciprofloxacin by iron cations in the gastrointestinal tract, relevant only if iron is taken orally.
What to do
With parenteral iron dextran no separation is needed. If any oral iron is used, give ciprofloxacin at least 2 hours before or 6 hours after it.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
