Complications
Although myocardial infarction during anaphylaxis is uncommon, cardiac ischaemia may be triggered by hypotension associated with anaphylaxis, or by the hypertension and tachycardia that often follows the administration of adrenaline (epinephrine).
Individuals with previous anaphylactic reactions are at higher risk for recurrence.[51] However, the severity of a previous reaction does not necessarily predict the severity of a subsequent one.[43]
Treatment involves immediate administration of adrenaline (epinephrine), which is crucial for improved outcome and prognosis.
If the inciting allergen is unknown, clinical and laboratory tests should be performed to determine the cause. Advise patients to avoid this allergen in the future.
