Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehabilitation facility who realize how challenging and difficult methadone detoxification can be. Methadone detoxification is known to be far more severe in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detox must 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 handle all addiction issues.
