3-Allylfentanyl
3-Allylfentanyl is an opioid analgesic that is an analogue of fentanyl.
3-Allylfentanyl has similar effects to fentanyl. Side effects of fentanyl analogs are similar to those of fentanyl itself, which include itching, nausea and potentially serious respiratory depression, which can be life-threatening. Fentanyl analogs have killed hundreds of people throughout Europe and the former Soviet republics since the most recent resurgence in use began in Estonia in the early 2000s, and novel derivatives continue to appear.
