How many A TNAA auto injections should you administar to yourself or to a casualty before seeking medical attention?

You should administer up to three auto-injections of epinephrine (like an EpiPen) for severe allergic reactions or anaphylaxis before seeking medical attention. If symptoms do not improve or worsen after the first injection, a second and possibly third injection can be given every 5 to 15 minutes as needed. Always call for emergency medical help immediately after administering the first dose. It's crucial to seek professional medical care regardless of the outcome after the injections.
