[Which medications are safe while breastfeeding? : A synopsis for the anesthetist, obstetrician and pediatrician].

Pharmacokinetic data on drug administration during lactation are often inconsistent or missing. For legal reasons medicinal drug product information generally advises to interrupt breastfeeding for 24 h after medication intake. However this is not standard of care in clinical practice as the mother should be instructed to initiate breastfeeding as soon as possible after giving birth. At the same time the medication exposure over the breast milk for the newborn should be minimized. Aim of this article is to summarize pharmacokinetic data and to give important clinical information on medications frequently administered during the lactation period. As a general rule a mother can start breastfeeding following anesthesia as soon as she is able to get her baby latched on her breast.
