Methadone detoxification is a process which should be supervised by addiction professionals within a drug rehabilitation facility who understand 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 often 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 close supervision at a drug rehab program which has experience in handling this type of detox, and where the individual can receive additional treatment services to address all addiction issues.
