Methadone detoxification is a process which should be overseen by drug addiction professionals within a drug rehab facility who realize how difficult and challenging methadone detoxification 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 ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox should only be done under strict supervision at a drug rehab program which has practical experience in dealing with this type of detoxification, and where the person can receive additional treatment services to handle all addiction issues.
