title: Case of drug-induced acute pancreatitis produced by horsetail infusions.
abstract: BACKGROUND
  The most frequent causes of acute pancreatitis are biliary stones, alcohol consumption, smoking and tumors. Some of them do not have any established cause, and they are catalogued as idiopathic pancreatitis.
  
  
  METHODS
  We report the case of a 56-year-old woman with a history of bilateral adrenalectomy on hormone replacement therapy with corticosteroids, who has recurrent episodes of mild acute pancreatitis with an etiologic study (laboratory and imaging tests) without significant findings. A drug-induced etiology was suspected, so corticosteroids were removed and antihypertensive treatment was modified, but the clinical manifestations persisted. Later regular consumption of horsetail infusions was detected, and after their suspension the patient became asymptomatic and has not presented new episodes.
  
  
  CONCLUSIONS
  The drug-induced acute pancreatitis is a strange cause of pancreatitis that is frequently underdiagnosed because of the difficulty to establish a relationship between the drugs and the pancreatitis. Lots of drugs have been related with acute pancreatitis, while the information available for herbal products is limited. They usually present like mild and recurrent episodes, without significant findings in both laboratory and imaging tests (abdominal ultrasound, abdominal computed tomography [CT], cholangiography and endoscopic ultrasound). It is important to detect the origin of this type of pancreatitis to prevent recurrence.
