Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehab center who recognize how challenging and difficult methadone detoxification can be. Methadone detox is regarded 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 ease symptoms. This is why methadone detox should only be done under close supervision at a drug rehabilitation program which has experience in handling this type of detox, and where the person can receive additional rehabilitation services to handle all addiction issues.
