Methadone or suboxone taper: severity of symptoms and signs of opioid withdrawal is affected by a variety of factors such as amount of opioid used, half life of drugs, purity of drugs, route of administration, and opioid type. People who experience severe withdrawal symptoms would benefit from a taper program where a standard dose of methadone or suboxone is initiated and the dose is reduced in a daily basis.
Methadone or Buprenorphine maintenance program: to reduce the risk of relapse after detoxification, some individuals would need to be on replacement therapy where methadone or buprenorphine is prescribed for a longer period of time.
