Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab center who recognize how difficult and challenging methadone detoxification can be. Methadone detoxification is known 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 detoxification should only be done under close supervision at a drug rehabilitation facility which has practical experience in dealing with this type of detox, and where the person can receive further rehabilitation services to address all addiction issues.
