Methadone detoxification is a process which must be overseen by drug addiction professionals within a drug rehab facility who realize how challenging and difficult methadone detoxification can be. Methadone detoxification 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 ease symptoms. This is why methadone detoxification 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 person can receive additional rehabilitation services to deal with all addiction issues.
