Breastfeeding and Drugs

Talk to your health care provider about medications you are taking, or are about to take, while breastfeeding.

Most medications are safe to take while breastfeeding.

A health care professional can help you to make an informed choice about your safest options regarding prescription medications, over-the-counter drugs, herbal preparations or supplements. The risks to your baby of not breastfeeding and giving your baby infant formula may be higher than continued breastfeeding while using a drug. 

Using recreational or street drugs, including cannabis (marijuana), while breastfeeding may be harmful to you and your baby.  It is well known that your child’s brain develops very quickly during early childhood. Since exposure to cannabis could cause changes in your child’s brain it is best not to use any form of cannabis while breastfeeding.
