Methadone detoxification is a process which must be overseen by drug addiction professionals within a drug rehabilitation facility who understand how difficult and challenging methadone detoxification can be. Methadone detox is regarded to be far more serious in terms of symptoms and duration than even heroin detox, and individuals often revert back to methadone to relieve withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to relieve symptoms. This is why methadone detox must only be done under close supervision at a drug rehab program which has experience in dealing with this type of detox, and where the person can receive additional rehabilitation services to handle all addiction issues.
