[Breast milk and drugs]

This review deals with the transfer of drugs into breastmilk and its possible threat for the infant. The following groups of pharmaca are discussed: antibiotics, antiepileptics, psychotropic drugs, cardiac drugs, diuretics as well as some other compounds. Social drugs and ecological poisons are also considered. Medications which are contraindicated during lactation and may lead to prohibition of nursing an infant have been tabulated. In general it still is valid, that despite of the vast number of possibly interfering substances in breast milk, nursing of the infant remains the best and most reliable means of infant feeding and rearing.
