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 detox can be. Methadone detox is known to be far more severe 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 detoxification should only be done under strict supervision at a drug rehab center which has experience in handling this type of detox, and where the individual can receive further treatment services to handle all addiction issues.
