Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehab facility who understand how difficult and challenging methadone detoxification can be. Methadone detoxification is known 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 relieve symptoms. This is why methadone detox must only be done under strict supervision at a drug treatment facility which has experience in dealing with this type of detoxification, and where the individual can receive further rehabilitation services to deal with all addiction issues.
