This medication contains 2 medicines buprenorphine and naloxone. It is used to treat opioid dependence/addiction. Buprenorphine belongs to a class of drugs called mixed opioid agonist-antagonists. Buprenorphine helps prevent withdrawal symptoms caused by stopping other opioids.
Naloxone is an opioid antagonist that blocks the effect of opioids and can cause severe opioid withdrawal when injected. Withdrawal is less likely when naloxone is taken by mouth, dissolved under the tongue, or dissolved on the inside of the cheek. It is combined with buprenorphine to prevent abuse and misuse (injection) of this medication. This combination medication is used as part of a complete treatment program for drug abuse (such as compliance monitoring, counseling, behavioral contract, lifestyle changes).
