Corticosteroids have no immediate effect on anaphylaxis. [74] However, administer them early to try to prevent a potential late-phase reaction (biphasic anaphylaxis). Patients with asthma or other conditions recently treated with a corticosteroid may be at increased risk for severe or fatal anaphylaxis and may receive additional benefit if corticosteroids are administered to them during anaphylaxis. The authors recommend corticosteroid treatment for all patients with anaphylaxis. If absorption is a concern, IV preparations should be used.
