Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehab center who realize how difficult and challenging methadone detoxification can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and users often 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 must only be done under close supervision at a drug rehab center which has practical experience in handling this type of detoxification, and where the person can receive additional treatment services to deal with all addiction issues.
