Methadone detoxification is a process which must be supervised by drug addiction professionals within a drug rehab program who realize how challenging and difficult methadone detox can be. Methadone detoxification is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehab program which has experience in dealing with this type of detoxification, and where the individual can receive further recovery services to deal with all addiction issues.
