Methadone detoxification is a process which should be supervised by addiction professionals within a drug rehab program who understand how challenging and difficult methadone detoxification 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 relieve 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 rehabilitation center which has practical experience in handling this type of detoxification, and where the person can receive further treatment services to deal with all addiction issues.
