Q:

7/22/2013
I have recently been asked questions regarding wasp stings and breast feeding and find there is a paucity of data on the subject. Can you please enlighten me on advice to give concerned mothers regarding this subject? My advice has been it should not affect the breast milk, but I am not sure if it can sensitize a child? Thank you.

A:

Thank you for your inquiry.

Unfortunately, I cannot give you any evidence-based opinion because I am not aware of nor could I find any information on this topic via a literature search. Nonetheless, I think it would be highly unlikely for an infant to be sensitized to venom via transmission of the venom through breastfeeding. To my knowledge there are no known cases of transmission of sensitization via the administration of allergy injections (an analogous exposure) through breast milk, and the limited data that we have indicate that infants born to atopic mothers who take allergy injections may have a reduced incidence of atopic disease (submitted for presentation at the AAAAI meeting 2013). Thus, I think we could offer at least some reassuring information to the concerned mothers who have inquired about this issue.

Thank you again for your inquiry and we hope this response is helpful to you.

Sincerely,
Phil Lieberman, M.D.
