Thanks for asking at Healthcare Magic. I read your question and I understand Your concern. Metaphage is safe in lactation. As the amount of drug excreted in breast milk is very low. As the drug is excreting at same steady concentration. Hence There is no need to keep interval between breastfeeding and drug dosage. Hope it helps best. Don t forget to rate this answer and close the discussion at Healthcare Magic and vote it helpful if found beneficial. Take your best care. Regards Dr Ejaz
