Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab program who realize 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 individuals 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 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 address all addiction issues.
