National Breastfeeding Week: Medications and Breast Milk

Jarod Cassidy2 months ago

Breastfeeding

New and expecting mothers making the decision to breastfeed do understanding that breast milk is an excellent way for their child to receive nutrition and sustain development. They also understand that breast milk can transmit chemicals that are potentially hazardous to their child and adjust their lifestyle accordingly.

However, while it’s easy to remember that the transmission of alcohol and illicit drugs through breast milk can seriously hamper a child’s growth and development, understanding which pharmaceuticals pose a similar threat is much more difficult.

In recognition of National Breastfeeding Week, Thomas J. Henry would like to share a list compiled by Baby Center which categorizes some the most widely used pharmaceuticals based on breastfeeding safety. Please note that even if a medication is considered safe, mothers should consult with their physician if they have any questions or concerns that a medication or combination of medications may pose a hazard to their nursing infant.
