Fentanyl Injection

Pronunciation

Generic Name: fentanyl injection
Brand Names: Sublimaze

On January 27, 2014, The New York Times reported 22 deaths in Pennsylvania linked to a dangerous batch of heroin. The overdose deaths were most likely caused by a mix of heroin and fentanyl, an extremely dangerous and potentially lethal combination for users.

The February 2, 2014 death of actor Philip Seymour Hoffman from drug overdose has highlighted the growing problem of addicts purchasing contaminated heroin. Some officials fear that efforts to drive down abuse of prescription medications could be contributing to rising heroin use.

What is fentanyl injection?

Fentanyl is a narcotic (opioid) analgesic. It works in the brain and nervous system to cause anesthesia and decrease pain.

Fentanyl is used for producing anesthesia for surgery and treating pain before, during and after surgery.
