Methadone detoxification is a process which should be supervised by drug addiction professionals within a drug rehab program who understand how challenging and difficult methadone detoxification 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 detoxification must 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 additional treatment services to address all addiction issues.
