Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab facility who realize how difficult and challenging methadone detox can be. Methadone detoxification is known to be far more serious in terms of symptoms and duration than even heroin detox, and users typically revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox should only be done under close supervision at a drug rehabilitation center which has experience in dealing with this type of detox, and where the individual can receive additional recovery services to deal with all addiction issues.
