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