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