Methadone detoxification is a process which should be overseen by substance abuse professionals within a drug rehab program who realize how difficult and challenging methadone detoxification can be. Methadone detox 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 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 close supervision at a drug rehab center which has practical experience in dealing with this type of detox, and where the individual can receive additional rehabilitation services to deal with all addiction issues.
