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 detoxification can be. Methadone detox is regarded to be far more serious 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 relieve symptoms. This is why methadone detox must only be done under close supervision at a drug treatment center which has experience in handling this type of detoxification, and where the individual can receive further rehabilitation services to handle all addiction issues.
