The LactMed database is a searchable database that contains information about medication use while breastfeeding. The data comes from current scientific literature and is reviewed by a peer review panel to ensure accuracy. You can search the database for a specific medication to learn the level of medication that is known to cross into breast milk and infant blood, as well as the possible adverse effects in the nursing infant. The database also provides suggested therapeutic alternatives, where appropriate.
