First-line treatment of anaphylaxis in an adult is intramuscular adrenaline 500 micrograms into the anterolateral thigh, repeated after five minutes if there is no improvement. Intravenous adrenaline 1 mg (B) is the cardiac arrest dose and is dangerous in a patient with a circulation. Steroids (D) are no longer routinely recommended in the 2025 guidance and are not first-line. The single most important drug in anaphylaxis is intramuscular adrenaline, given promptly.
