Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehabilitation center who realize how difficult and challenging methadone detoxification can be. Methadone detox 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 ease symptoms. This is why methadone detox must only be done under close supervision at a drug rehab center which has experience in dealing with this type of detoxification, and where the person can receive additional rehabilitation services to handle all addiction issues.
