Correct answer: E — Avoid taking ciprofloxacin with milk or calcium because absorption is reduced

Calcium, dairy products and antacids can chelate ciprofloxacin and reduce absorption. The antibiotic should be separated from calcium-containing products according to product guidance. Tendon symptoms should be reported, but calcium does not prevent this risk. The patient should complete the course as prescribed unless advised otherwise.
