Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab center who understand how challenging and difficult 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 often revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detoxification should only be done under close supervision at a drug treatment facility which has practical experience in handling this type of detoxification, and where the person can receive additional rehabilitation services to handle all addiction issues.
