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