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