Methadone detoxification is a process which must be overseen by drug addiction professionals within a drug rehabilitation program who realize how difficult and challenging methadone detox can be. Methadone detox is known to be far more serious in terms of symptoms and duration than even heroin detox, and individuals often revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detox should only be done under close supervision at a drug rehab facility which has experience in dealing with this type of detox, and where the individual can receive additional treatment services to address all addiction issues.
