In anaphylaxis, after calling 999, what is the next action?

• A. Maintain airway and administer oxygen
• B. Administer intramuscular adrenaline
• C. Perform BLS and defibrillation if needed
• D. Call 111 for advice

Answer: (B)

Adrenaline works fastest to reverse the life-threatening effects of anaphylaxis—airway swelling, bronchospasm, and shock. Because it tackles these processes directly, giving an intramuscular adrenaline dose promptly is the most important next step after you’ve called for emergency help. Administer it into the mid-outer thigh as soon as the drug is available (for an adult, typically 0.5 mg of a 1:1000 solution). If symptoms persist or recur, a second dose can be given after a short interval if you’re trained to do so. After administering adrenaline, stay with the person, keep them in a safe position (usually flat, with legs raised if possible), monitor breathing and consciousness, and provide oxygen if available. Continue to seek advanced care and be prepared to start BLS if the person stops breathing.
