Methadone detoxification is a course of action which must be supervised by drug addiction professionals within a drug rehabilitation facility 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 ease withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detox must only be done under close supervision at a drug rehab center which has practical experience in handling this type of detoxification, and where the person can receive further rehabilitation services to address all addiction issues.
