Systemic steroid withdrawal can provoke pustular psoriasis

Ask about psoriasis before any systemic steroid course, and plan the taper if one is unavoidable.

Stopping or tapering systemic corticosteroids in a patient with psoriasis is a recognised trigger of generalised pustular psoriasis. Before prescribing oral steroids for another condition, ask about psoriasis. If a steroid course is unavoidable, plan the taper with the dermatologist and warn the patient to report widespread pustules or fever promptly.

  • Ask about psoriasis before prescribing oral corticosteroids.
  • Avoid systemic steroids for psoriasis itself.
  • If steroids are needed for another reason, taper slowly and review the skin.
  • Warn patients to seek help for sudden pustules with fever.

Why it matters

A short steroid course given elsewhere can end in a dermatology admission.
