Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehab program who understand 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 frequently 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 must only be done under close supervision at a drug rehab center which has practical experience in dealing with this type of detoxification, and where the person can receive further rehabilitation services to address all addiction issues.
