We know it takes more than facts to make decisions. Sometimes you need guidance from a seasoned expert, help resolving conflicting information, or even just a little reassurance about your choice.  Thanks to the generosity of the David D. & Nona S. Payne Foundation, we have a free call center for parents or providers, staffed by experienced nurses trained by Drs. Hale and Krutsch.

Lactation Risk Categories Explained

Drs. Thomas Hale and Kaytlin Krutsch have performed extensive research on the effects of medications in mother’s milk. They have given each medication a rating from Safest (L1) to Hazardous (L5).


L1 Safest: Extensive evidence demonstrating no adverse effects on the infant


L2 Safer: Limited evidence without an increase in adverse effects on the infant


L3 Probably Safe: No studies, but expert opinion suggesting safety. Risk to the infant is possible, and further evaluation must be taken to consider individual situations.


L4 Possibly Hazardous: Positive evidence or expert opinion of risk to the infant or milk production.


L5 Hazardous: Significant and documented risk to the infant. Contraindicated
