We are in the process of developing general guidelines for taking care of MCAS patients with anaphylaxis s/sx admitted to urgent care or ED from our outpatient Allergy clinic.
The key questions are what medications and doses are to be used (e.g. diphenhydramine IVP vs. infusion) and what level of monitoring is warranted.
There is a lack of good quality literature on this subject. I would greatly appreciate any insight or best practices you could share.
