Methadone detoxification is a course of action which must be overseen by drug addiction professionals within a drug rehab program who understand how challenging and difficult methadone detoxification can be. Methadone detox is known to be far more serious in terms of symptoms and duration than even heroin detox, and users often 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 rehabilitation facility which has experience in dealing with this type of detoxification, and where the individual can receive additional treatment services to deal with all addiction issues.
