Systemic capillary leak syndrome (SCLS) frequently causes complex medical problems involving many body systems. SCLS "attacks" are typically sudden, although sometimes certain warning signs or symptoms, such as body ache, flu-like symptoms, scratchy throat or dark urine, can alert you. An attack of SCLS may include a marked drop in blood pressure, which if not treated promptly, can lead to multiple organ failure and death. During an episode of SCLS, treatment may include:

  • Fluids. Fluids are given intravenously and carefully controlled to maintain your blood pressure and to prevent damage to vital organs, such as your kidneys, heart and brain.
  • Medications. Your doctor may order medications, such as steroids, diuretics or immunoglobulin, among others. Over the long term, medications are usually prescribed to reduce the frequency and severity of future episodes.
