What criteria should I use to determine whether to refer a patient with SJS/TEN to secondary care?

Refer patients with Stevens-Johnson Syndrome (SJS) or Toxic Epidermal Necrolysis (TEN) to secondary care immediately. These conditions are classified as severe non-immediate cutaneous drug reactions requiring specialist management and hospital admission for acute treatment and monitoring.

Specifically, if a patient presents with suspected SJS or TEN, stop the suspected causative drug and arrange urgent referral to hospital for specialist care.

Document the suspected drug allergy in the patient's medical records and provide information about the reaction and drug avoidance.
