Methadone detoxification is a process which must be overseen by addiction professionals within a drug rehabilitation facility who realize 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 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 rehabilitation program which has practical experience in dealing with this type of detoxification, and where the individual can receive additional treatment services to deal with all addiction issues.
