Breastfeeding Allergy

Anaphylaxis to Breastfeeding

Anaphylaxis can occur as a result of breastfeeding.

Anaphylaxis to Breastfeeding

Anaphylaxis in a breastfeeding woman is a rare medical condition. Symptoms occur in the breastfeeding mother, and can include urticaria and angioedema shortly after the woman breastfeeds, although symptoms can be more severe and even include anaphylaxis. The cause of breastfeeding allergy is not completely clear, but most likely involves various hormones that are active during breastfeeding, such as prolactin and oxytocin.

A report of breastfeeding allergy occurred in a woman three days after the birth of a third child, and only during breastfeeding. Similar symptoms happened after the birth of her second child. Other causes of allergy, including to foods, medicines, and latex, were not found.

Women who experience allergic reactions with breastfeeding may be able to control symptoms with the use of antihistamines. Those with severe symptoms should have access to injectable epinephrine and may consider stopping breastfeeding.
