Question
You’re overrunning on your ward visit and as you try to leave the ward Sister asks you about a patient who is breastfeeding her 3-month-old child but who has been started on ciprofloxacin. The patient has been advised to stop breastfeeding whilst taking the antibiotic and the Sister wants to know when she can restart. The patient has an intra-abdominal infection and has been prescribed ciprofloxacin 500mg twice daily for 7 days. Upon questioning you establish that the child is healthy and was born term.




Outcome
Whilst you are on the ward you check the manufacturer’s prescribing information. It confirms that ciprofloxacin should not be used whilst breastfeeding. This is because of the potential risk of joint damage to the child. However the SPC does not give any advice about resuming feeding once the drug has been stopped.

You drop into the medicines information office on your way back from the ward to consult some specialist lactation resources. These advise that the amount of ciprofloxacin that passes into the breast milk is actually quite low, and that quinolones are generally considered safe to use in mothers who are breastfeeding. Waiting 3-4 hours after each dose before feeding can minimise infant exposure to the drug. Joint damage has only been reported in children taking quinolones themselves and not those exposed via the breast milk. Gastrointestinal side effects and oral candida might be expected in the child, especially with higher doses.

Armed with your findings you go back to the ward and establish that the patient decided to stop breastfeeding herself after reading a parenting forum online. You explain that the risks posed to her child are actually quite low and are probably outweighed by the benefits of continuing to breastfeed. Reassured by your advice, the patient decides that she wants to resume breastfeeding. You counsel her to avoid feeding immediately after a dose of the antibiotic and on the side effects that her child might experience. Finally you document your advice in the patient’s medical and nursing notes and speak to the ward Sister.
