Methadone detoxification is a course of action which must be supervised by substance abuse professionals within a drug rehabilitation program who understand how difficult and challenging 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 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 detox must only be done under strict supervision at a drug rehab center which has experience in handling this type of detoxification, and where the person can receive additional treatment services to deal with all addiction issues.
