Target exams

Red flags

• Anaphylaxis within minutes to one hour of a drug — airway, breathing or circulation compromise; give intramuscular adrenaline immediately and never re-challenge
• Blistering, skin pain, target lesions or mucosal involvement — Stevens-Johnson syndrome or toxic epidermal necrolysis; stop the drug and treat as an emergency; permanent contraindication
• Rash with fever, lymphadenopathy, eosinophilia or organ dysfunction two to eight weeks after a drug — DRESS; never re-challenge
• Sterile pustules with fever and acute onset — acute generalised exanthematous pustulosis (AGEP); specialist evaluation, never re-challenge
• A child carrying a penicillin-allergy label who now needs a beta-lactam for serious infection — verify the label rather than defaulting to a second-line agent
