Medications and Drugs

Brand Names: Suboxone

Generic Name: buprenorphine and naloxone (Pronunciation: byoo PREH nor feen and NAH lox own)

What is buprenorphine and naloxone (Suboxone)?

Buprenorphine is an opioid medication. Buprenorphine is similar to other opioids such as morphine, codeine, and heroin however, it produces less euphoric ("high") effects and therefore may be easier to stop taking.

Naloxone blocks the effects of opioids such as morphine, codeine, and heroin. If buprenorphine and naloxone is injected, naloxone will block the effects of buprenorphine and lead to withdrawal symptoms in a person with an opioid addiction. When administered under the tongue as directed, naloxone will not affect the actions of buprenorphine.

Buprenorphine and naloxone is used to treat opiate addiction.

Buprenorphine and naloxone may also be used for purposes other than those listed in this medication guide.
