Are there currently any recommendations regarding postponing skin testing to penicillin or foods for a certain time period after the initial reaction as there are with venom testing? I have reviewed the current guidelines and searched articles but have not found any such recommendation.


Thank you for your inquiry.

I am not aware of any formalized guidelines dealing with this subject, and could find none on a literature search. But, in general, it is recommended that there be a two week delay before performing skin testing to any potential culprit after a systemic allergic event. I would personally suggest such a delay.

Thank you again for your inquiry.
