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