Methadone detoxification is a process which must be overseen by drug addiction professionals within a drug rehab facility who understand how challenging and difficult methadone detox can be. Methadone detoxification is known to be far more serious in terms of symptoms and duration than even heroin detox, and individuals typically 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 should only be done under close supervision at a drug rehab center which has practical experience in handling this type of detoxification, and where the individual can receive further treatment services to deal with all addiction issues.
