title: Which drugs are contraindicated during breastfeeding? Practice guidelines.
abstract: OBJECTIVE
  Many breastfeeding mothers are concerned about taking medications that might affect their babies. Are there any guidelines on which drugs are safe?
  
  
  CONCLUSIONS
  Only a few drugs pose a clinically significant risk to breastfed babies. In general, antineoplastics, drugs of abuse, some anticonvulsants, ergot alkaloids, and radiopharmaceuticals should not be taken, and levels of amiodarone, cyclosporine, and lithium should be monitored.
