title: [Cognitive and behavioural alterations as adverse reaction to tamsulosin not previously described].
abstract: OBJECTIVE
  To report one case of adverse reaction to tamsulosin.
  
  
  METHODS
  We describe the case of an 80-year-old patient who was started on alpha blocker treatment after acute urinary retention with the aim to perform a voiding test.
  
  
  RESULTS
  The patient presented self-limited episodes of disorientation in time and space and abnormal behaviour in coincidence with the first three administrations of the drug. Treatment was stopped.
  
  
  CONCLUSIONS
  We report one case of an adverse reaction to tamsulosin not previously described. We make a reference to the drug vigilance mechanisms. We point out the importance of coordination between health-care levels.
