An autopsy shows a woman who died at the Duke University hospital earlier this year suffered an overdose of a common antihistamine and a pain reliever.
Multiple media outlets report that 30-year-old Cheryl Lynn Suber of Garner died in October 5 from overdoses of oxycodone and the allergy medicine diphenhydramine, or Benadryl.
A nurse found Suber after her boyfriend asked the nurse to check on her.
Hospital staff found two syringes they didn't recognize in Suber's bed. They were labeled "saline" but contained a pink liquid. The medical examiner's office later identified it as diphenhydramine, which had not been prescribed to Suber.
Duke University police are investigating.
Suber suffered from sickle cell anemia and had gone to the hospital for chest pains.
