Is Buprenex the same as buprenorphine?

Yes, Buprenex is the brand name for an injectable form of buprenorphine. Buprenex (generic name: buprenorphine) is a potent opioid (narcotic) medication used to manage pain severe enough to require an opioid analgesic and for which alternate treatments are inadequate.

Buprenex is considered a partial mu opioid agonist and was approved by the FDA in 1981. It activates the mu opioid receptor to a lesser extent than the full opioid agonists (like oxycodone, methadone or morphine). It is given as an intravenous (IV) or intramuscular (IM) injection and is classified as a Schedule III controlled substance by the DEA.

Buprenex has certain limitations of use when prescribed, as well.

• Due to risks of addiction and misuse with opioids such as Buprenex, it is only used when you cannot tolerate other pain medication or have not had adequate relief (or you are not expected to have adequate relief).
• Examples of these medicines include non-opioid medications (for example: NSAIDs like ibuprofen or naproxen) or combination opioids (for example: acetaminophen and hydrocodone).

Buprenex is used after surgery and for the relief of severe pain associated with conditions such as cancer, kidney stones, and nerve disorders (neuropathic pain). You would usually receive this medication in a clinic or hospital setting and would receive monitoring by your doctor.

Although Buprenex is an FDA-approved medication, it has serious warnings and side effects and can be fatal if abused, taken in too high of a dose, or combined with other medicines that can increase sedation or respiratory depression (slowed breathing). Talk to your doctor about how to safely use any form of buprenorphine.

Buprenex is manufactured by Indivior Inc., who also make Sublocade and Suboxone.

What is buprenorphine used to treat?

Brand names examples of single ingredient buprenorphine products used to treat opioid dependence (opioid use disorder) include:

Buprenorphine is also found in combination with naloxone for treatment of opioid dependence and addiction (opioid use disorder).
