Methadone detoxification is a course of action which must be supervised by addiction professionals within a drug rehabilitation facility who recognize 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 relieve 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 experience in dealing with this type of detox, and where the person can receive additional rehabilitation services to address all addiction issues.
