Risk of Anaphylactic Reaction Although it is known that patients on beta-blockers may be refractory to epinephrine in the treatment of anaphylactic shock, beta-blockers can, in addition, interfere with the modulation of allergic reaction and lead to an increased severity and/or frequency of attacks.
Such patients may be unresponsive to the usual doses of epinephrine used to treat allergic reaction.
