A 49-year-old female was found unresponsive in her house by her husband and was transported by ambulance to the hospital emergency department. She had recently been diagnosed and treated for depression. Her husband found two prescription bottles empty. These had recently been filled. One was for Lexapro, the other for Ativan. He also found a suicide note on the coffee table. The ED department physician talked with the patient's psychiatrist, who confirmed that these had recently been prescribed. An empty bottle of vodka was also found near the patient's body. The ED examination and toxicology studies confirmed a drug overdose of these two medications and alcohol.

Sadly, while the patient was being treated, she suffered a cardiopulmonary arrest and died. The physician documented poisoning in a suicide attempt with citalopram, lorazepam, and vodka.
