Methadone detoxification is a process which must be overseen by addiction professionals within a drug rehab facility who understand 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 individuals 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 must 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 individual can receive further treatment services to address all addiction issues.
