Methadone detoxification is a course of action which must be overseen by substance abuse professionals within a drug rehab program who understand how challenging and difficult 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 frequently revert back to methadone to ease 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 rehabilitation program which has experience in dealing with this type of detox, and where the person can receive additional rehabilitation services to address all addiction issues.
