Resources on Medications in Human Milk

Lactation consultants are often asked about the safety of various maternal medications during lactation, which is but one aspect of education and training for the International Board Certified Lactation Consultant (IBCLC).  Since the early 1990s, our profession has often referred to the invaluable text, Hale's Medications and Mothers' Milk by Thomas W. Hale RPh PhD, and on May 28th, the 19th edition of this important volume will be released.  Dr. Hale also founded the InfantRisk Center, which addresses maternal medications during lactation and more about infant health and wellbeing. 

Dr. Frank J. Nice offers the text, Nonprescription Drugs for the Breastfeeding Mother, now in its 2nd edition. 

The U.S. National Institutes of Health's Toxicology Database offers LactMed to professionals as well as the general public, and is another invaluable resource on drugs in human milk.  Most medications are compatible with breastfeeding, and in instances of a medication that is not compatible, an alternative medication is often safely prescribed.
