Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehab program who recognize 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 frequently revert back to methadone to relieve 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 rehab center which has experience in handling this type of detoxification, and where the individual can receive further treatment services to handle all addiction issues.
