Narcotics (opioids): Veterinarians will sometimes use narcotics, such as morphine, codeine, hydrocodone, fentanyl or buprenorphine, for controlling severe pain when other medications are not strong enough.
Some of the medications drug rehab programs can treat opioid addiction include methodone, LAAM (levo-alpha-acetyl-methadol), naltrexone, naloxone, and buprenorphine.
Additionally, medications like methadone or buprenorphine may be given to patients during the treatment process.
Another drug that has been approved for treating heroin addiction is buprenorphine.
Some physicians will prescribe buprenorphine which is a different type of opioid.
