What medications are safe while breastfeeding?

Sometimes parents receive conflicting information about what medications are compatible with lactation. As research continues to develop in this area, check before assuming you must “pump and dump” or alter your care plan then share this information with your healthcare providers to determine the next steps.

A top recommendation is

The InfantRisk Center ( Call center: 1 (806) 352-2519, 8:00 AM - 3:00 PM CST, Monday- Friday. Apps available: MommyMeds (for parents) or InfantRisk HCP (for providers).

“The InfantRisk Center (IRC) is a world-wide call center presently in the Texas Tech University Health Sciences Center, School of Medicine, Department of Pediatrics, in Amarillo. 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
