EMS brings in a 22 year old male who has presented multiple times previously with suicidal gestures. Tonight, they state he took an unknown quantity of acetaminophen about 4 hours prior to arrival. You draw a 4 hour acetaminophen level, and it is 105. Feeling good that he is below the treatment threshold, you are just about to call the psychiatrist when the patient tells you he actually ingested “Tylenol PM.” Does this matter? Is the patient medically clear?
The answer later this week, unless you come up with it first!
