Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehabilitation center who understand how difficult and challenging methadone detox can be. Methadone detoxification 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 ease 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 dealing with this type of detox, and where the individual can receive additional treatment services to handle all addiction issues.
