Methadone detoxification is a course of action which must be overseen by substance abuse professionals within a drug rehabilitation facility 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 alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detoxification must only be done under close supervision at a drug rehab program which has experience in handling this type of detox, and where the person can receive additional treatment services to deal with all addiction issues.
