Methadone detoxification is a process which must be supervised by drug addiction professionals within a drug rehabilitation program who understand how difficult and challenging 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 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 strict supervision at a drug rehabilitation center which has practical experience in dealing with this type of detox, and where the individual can receive additional rehabilitation services to address all addiction issues.
