National Library of Medicine Now Licensing LactMed

National Library of Medicine Now Licensing LactMed. NLM Tech Bull. 2015 May-Jun;(404):b12.

2015 June 11 [posted]

June 8, 2015, the National Library of Medicine (NLM) began licensing the Toxicology Data Network (TOXNET) dataset Drugs and Lactation Database (LactMed).

Current licensees may contact the NLM Data Distribution team at and request to have the dataset added to their license. New licensees may request the dataset when applying for a license.

LactMed is a database of drugs and other chemicals to which breastfeeding mothers may be exposed. It includes information on the levels of such substances in breast milk and infant blood, and the possible adverse effects in the nursing infant. Suggested therapeutic alternatives to those drugs are provided, where appropriate. All data are derived from the scientific literature and fully referenced. Data are organized into substance-specific records, which provide a summary of the pertinent reported information and include links to other NLM databases. Supplemental links to breastfeeding resources from credible organizations are also provided.
