What should you do if a patient shows signs of severe allergic reaction?

A severe allergic reaction, also known as anaphylaxis, is a life-threatening condition that requires immediate intervention. One of the most critical treatments for anaphylaxis is the administration of epinephrine. Epinephrine works by constricting blood vessels, which helps to increase blood pressure, and by relaxing the muscles around the airways, which can alleviate difficulty breathing. This rapid action can significantly reduce the severity of the reaction and is often life-saving.

While providing oxygen and monitoring vitals are important components of managing respiratory distress and assessing a patient's condition, these measures alone do not address the underlying cause of the anaphylactic reaction. Transporting the patient to the hospital is also necessary for further treatment, but without administering epinephrine first, the patient's condition could worsen significantly during transport. Administering epinephrine promptly is crucial in managing severe allergic reactions effectively.
