Drugs and Breast Milk Interactions Chart
From: http://www.babycenter.com/general/baby/babybreastfeed/8790.html
Whether it is congestion brought on by allergies or pain associated with a more serious health problem, you're probably ready to head to the medicine
cabinet for some relief. Although many medications are safe to use while breastfeeding, almost any drug will get into your milk to some degree and can
occasionally affect your milk supply. To be safe, you should always check with your pediatrician or pharmacist before taking any kind of
medication, even over-the-counter drugs.

The information in the chart below was compiled by Philip Anderson, a pharmacist and the director of the Drug Information Service at the University of
California, San Diego Medical Center. If you have more questions about how a drug you are taking may affect your breast milk or your baby, call the
UCSD information service at (900) 226-7536, 9 a.m. to 5 p.m. Pacific time, Monday to Friday ($4 for the first minute, $2.50 for every additional minute).
