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