Methadone detoxification is a course of action which must be overseen by drug addiction professionals within a drug rehab center who understand how challenging and difficult methadone detoxification can be. Methadone detox is known to be far more severe in terms of symptoms and duration than even heroin detox, and users typically 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 strict supervision at a drug rehabilitation facility which has experience in dealing with this type of detoxification, and where the person can receive additional rehabilitation services to deal with all addiction issues.
