Methadone detoxification is a process which must be overseen by substance abuse professionals within a drug rehab facility who understand how challenging and difficult methadone detoxification can be. Methadone detoxification is regarded to be far more severe in terms of symptoms and duration than even heroin detox, and users often revert back to methadone to ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to alleviate symptoms. This is why methadone detoxification should only be done under close supervision at a drug treatment program which has practical experience in handling this type of detoxification, and where the individual can receive further treatment services to handle all addiction issues.
