What is the first step if you suspect anaphylaxis?

When someone is suspected of experiencing anaphylaxis, it is crucial to act quickly because this severe allergic reaction can lead to life-threatening symptoms such as airway constriction and cardiovascular collapse. Administering epinephrine (if available) is the first line of treatment for anaphylaxis. Epinephrine works by rapidly reversing the symptoms of an allergic reaction, including swelling and low blood pressure.

Calling 911 immediately after administering epinephrine is essential for ensuring that professional medical help is on its way. Anaphylaxis can progress quickly, and emergency responders can provide advanced care and further interventions.

Offering water, having the individual lie down and elevating their legs, or just waiting for help may not effectively address the immediate dangers posed by anaphylaxis and could potentially worsen the situation. Administering epinephrine and seeking emergency medical services is the most effective and life-saving action to take in response to a suspected anaphylactic reaction.
