title: Hyperkalaemic paralysis.
abstract: BACKGROUND
  hyperkalaemic paralysis is a rare, treatable, and potentially fatal entity presenting with flaccid motor weakness.
  
  
  METHODS
  a patient with acute hyperkalaemic paralysis caused by erroneous oral potassium supplementation in the context of chronic renal failure. The clinical picture of quadriplegia was initially interpreted as spinal cord injury due to a pathological cervical fracture.
  
  
  CONCLUSIONS
  the diagnosis of hyperkalaemic paralysis requires a high index of suspicion. Instructions for over-the-counter supplements must be clear and concise to prevent life-threatening medication errors.
