Methadone detox is a process which should always be undertaken with the assistance of drug rehab professionals in an alcohol and drug treatment center that understands how difficult and how much of a challenge methadone detoxification can be. Methadone detoxification is known to be far more severe in terms of symptoms of withdrawal and duration than even heroin detox, and persons sometimes relapse back onto methadone to ease symptoms of withdrawal or even worse begin abusing heroin or medical opioids to relieve symptoms. Due to this methadone detoxification should only be done under close supervision at a Keller drug detox facility that has expertise in handling this type of detoxification, and where the person can receive more extensive rehab services to address all addiction problems.
