How should you respond to suspected anaphylaxis if trained to assist with an auto-injector?

• A. Wait and observe for 10 minutes.
• B. Administer a first-generation antihistamine only.
• C. Remove the patient from exposure and give water.
• D. Call EMS, monitor the patient, and assist with an epinephrine auto-injector if trained, then transport.

Answer: (D)

Suspected anaphylaxis requires rapid treatment to support breathing and circulation and to prevent a rapid decline. The priority is to get advanced help while starting life-saving measures right away. If you’re trained to assist with an epinephrine auto-injector, administer it as soon as you can follow the instructions, then stay with the patient to monitor their condition and provide support.

Calling EMS ensures that ALS is en route if the reaction worsens or if there are airway or breathing issues, and it allows for potential additional treatments and transport to a hospital. After giving epinephrine, continue monitoring the patient and arrange for transport so they can receive definitive care and observation, since symptoms can recur or worsen after the first dose.

Antihistamines alone do not treat the rapid and potentially life-threatening effects of anaphylaxis, and simply removing exposure or giving water does not address the systemic reaction.
