title: Acetaminophen overuse in the Ohio Medicaid population.
abstract: OBJECTIVE
  To examine patterns of use of acetaminophen in patients with and without risk factors for hepatotoxicity in the Ohio Medicaid population.
  
  
  METHODS
  Retrospective, cross-sectional analysis of claims data.
  
  
  METHODS
  Ohio.
  
  
  METHODS
  Ohio Medicaid patients (n = 22,496) who received at least 6 prescriptions for acetaminophen from November 1998 through April 1999.
  
  
  METHODS
  Overuse of acetaminophen, defined as an average daily dose (ADD) greater than or equal to 4 grams/day or an ADD of greater than or equal to 3 grams/day along with diagnosis codes suggesting underlying liver dysfunction.
  
  
  RESULTS
  We identified 687 patients (3.05%) who received either greater than or equal to 4 grams/day or greater than or equal to 3 grams/day and had diagnosis codes suggesting underlying liver dysfunction (n = 128).
  
  
  CONCLUSIONS
  Although the number is relatively small, some Ohio Medicaid patients are receiving acetaminophen doses that exceed safety recommendations. Because acetaminophen overuse is the leading cause of liver failure, health care professionals should be alert to the possibility of acetaminophen overuse.
