مريض يأخذ مضاد حموضة يحتوي على الألومنيوم والمغنيسيوم مع مضاد حيوي سيبروفلوكساسين. أي تعليم صحيح؟

A client takes an aluminium–magnesium antacid with ciprofloxacin. Which teaching is correct?

1. Take them together to reduce stomach irritation
2. Separate the antibiotic from the antacid by at least two hours
3. Double the antibiotic dose to make up for the loss
4. Stop the antibiotic because it fails with antacids

Answer: B) Separate the antibiotic from the antacid by at least two hours. Metal ions in antacids bind quinolones and tetracyclines, reducing absorption. Take the antibiotic about 2 hours before or 6 hours after.
