Brand Name: Nubain

Nubain is used for:

Treating and preventing moderate to severe pain. It can also be used for pain relief before and after surgery and during childbirth. It may also be used for other conditions as determined by your doctor.

Nubain is an analgesic. It works by blocking certain receptor sites in the central nervous system, which helps to decrease pain.

Do NOT use Nubain if:

  • you are allergic to any ingredient in Nubain or to another opioid analgesic (eg, morphine or hydromorphone)
  • you have diarrhea due to poisoning, a certain type of bowel problem (pseudomembranous colitis), or are dependent on any medicine or substance
  • you are taking sodium oxybate (GHB)

Contact your doctor or health care provider right away if any of these apply to you.
