Unintended Consequences

In the opening scene, as Mariska Hargitay leaves her apartment with Brooke Shields, a book written by Linda Fairstein called "Silent Mercy" is partially obscured on her book stand. Fairstein is a former Assistant District Attorney turned author, who prosecuted sex crimes in the Manhattan District Attorney's Office.

When Rosemary overdoses Dr. Barkley, she says "it's fentanyl, all the Narcan in the world won't save him". While it is true that fentanyl is a very potent opioid (100 times more potent than morphine and 25 times more potent than heroin) a fentanyl overdose can be reversed with naloxone (Narcan), it just takes a larger dose of naloxone to reverse a fentanyl overdose than it would for a weaker opioid like morphine, heroin or oxycodone. Also the naloxone injection would need to be administered quickly as fentanyl has a much faster onset of action than most other opioids.
