Patient Education

Buprenorphine Sublingual and Buccal (opioid dependence)


Buprenorphine and the combination of buprenorphine and naloxone are used to treat opioid dependence (addiction to opioid drugs, including heroin and narcotic painkillers). Buprenorphine is in a class of medications called opioid partial agonist-antagonists and naloxone is in a class of medications called opioid antagonists. Buprenorphine alone and the combination of buprenorphine and naloxone work to prevent withdrawal symptoms when someone stops taking opioid drugs by producing similar effects to these drugs.
