Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehab center who understand how challenging and difficult methadone detoxification can be. Methadone detox is known to be far more serious 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 must only be done under close supervision at a drug rehabilitation facility which has experience in handling this type of detoxification, and where the person can receive further treatment services to handle all addiction issues.
