Abstract Disclosure: A. Hayat: None. N. Aslam: None. Primary adrenal insufficiency, or Addison's disease, is characterized by the inadequate production of cortisol and often requires lifelong hormone replacement therapy. COVID-19 vaccines have demonstrated overall safety, but this report explores a unique case of adrenal crisis post-vaccination in a patient with pre-existing adrenal insufficiency. A 38-year-old female, diagnosed with primary adrenal insufficiency, received her second dose of a COVID-19 vaccine. Within 48 hours after vaccine administration , she presented to the emergency department with severe fatigue, hypotension, nausea, and abdominal pain. Clinical examination and laboratory tests confirmed an adrenal crisis, with markedly decreased cortisol levels, hyponatremia, hyperkalemia, and an elevated ACTH level. The patient was promptly treated with intravenous hydrocortisone and saline fluids. Close monitoring of vital signs and cortisol levels was maintained, with a gradual tapering of hydrocortisone as the patient's symptoms improved. The importance of stress-dose steroids during illness or vaccination in patients with adrenal insufficiency is underscored. This case highlights that the Healthcare providers should be aware of this rare but severe complication and consider appropriate monitoring and stress-dose steroid coverage in susceptible populations.
