Anaphylactic and anaphylactoid reactions are serious allergic responses that require immediate treatment, presenting symptoms like bronchospasm, urticaria, and potentially fatal cardiovascular issues.
The case involves a 52-year-old male with an acute left thalamic hemorrhage and dangerously high blood pressure, initially treated with hydralazine, which proved ineffective.
While increasing the dose of nicardipine for better blood pressure control, the patient experienced severe side effects including swelling, urticaria, tachycardia, wheezing, and low oxygen saturation, indicating a serious reaction to the medication.
