Abstract:
We report two cases of prolonged blood clotting times as demonstrated by a raised international normalised ratio and elevated activated partial thromboplastin time in patients with cystic fibrosis taking ciprofloxacin. The potential mechanisms of a coagulopathy of this picture as an adverse drug reaction with ciprofloxacin are discussed along with the possible clinical consequences for patients with cystic fibrosis.
