What is U-47700?

U-47700 is a synthetic opioid developed in the 1970s by the Michigan-based pharmaceutical manufacturing firm Upjohn.

The painkiller is almost eight times stronger than morphine and is readily available, and affordable, online. U-47700’s extreme potency, and lack of government regulation, has health officials deeply concerned as overdoses rise.

U-47700 is commonly referred to as U-4, Pink or Pinky.

What does U-47700 look like?

How is U-47700 abused?

How does U-47700 affect a person?

U-47700 is a potent pain reliever. It can have several effects on the body including sedation, euphoria, itchiness, decreased libido, difficulty urinating, constipation and respiratory depression which could be harmful or fatal.

What are the health effects/risks of using U-47700?

Many users of U-47700 are being sedated to the point they stop breathing.

If the overdose is not immediately fatal and there is someone available to call for help, first responders can employ naloxene, an opiate antidote, in an effort to save a life. However, there are fears the effects of U-47700 are so strong it could be resistant to naloxene, especially when multiple doses are not available.

Unregulated drugs pose extreme danger as suppliers may practice inconsistent manufacturing practices. Each batch can have sizable variations in potency and makeup, putting users at high risk of a fatal overdose.
