Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehabilitation facility who recognize how challenging and difficult methadone detoxification can be. Methadone detox is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox should only be done under close supervision at a drug rehab program which has experience in handling this type of detox, and where the person can receive further rehabilitation services to deal with all addiction issues.
