Methadone detoxification is a process which should be supervised by substance abuse professionals within a drug rehab center who realize 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 individuals frequently 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 must only be done under close supervision at a drug rehab program which has experience in handling this type of detox, and where the individual can receive additional rehabilitation services to address all addiction issues.
