Correct answer: D — Intramuscular epinephrine

Airway symptoms plus hypotension after drug exposure indicate anaphylaxis, and intramuscular epinephrine is the first-line treatment. Antihistamines or salbutamol may help selected symptoms but do not treat shock or airway oedema adequately. The pearl is that epinephrine should not be delayed while waiting for rash progression.
