Methadone detoxification is a process which must be supervised by drug addiction professionals within a drug rehabilitation facility who recognize how difficult and challenging methadone detoxification can be. Methadone detox is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and users frequently revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detox should only be done under strict supervision at a drug rehab facility which has practical experience in handling this type of detox, and where the individual can receive additional treatment services to address all addiction issues.
