Methadone detox is a process which should always be overseen by drug rehab specialists in a drug rehabilitation facility that recognizes how difficult and challenging methadone detox is. Methadone detoxification is known to be far more severe when considering symptoms of withdrawal and duration than even heroin detox, and individuals sometimes relapse back onto methadone to alleviate symptoms of withdrawal or even worse begin abusing heroin or medical opioids to relieve symptoms. For this reason methadone detox should only be done under close supervision at a Clarendon Hills drug rehab which has expertise in addressing this form of detox, and where the individual who is detoxing may receive more extensive rehab services to address all substance abuse problems.
