A patient taking 120 mL alcohol everyday since last 12 years is brought to the hospital by his wife and is diagnosed to have alcohol dependence syndrome. Which of the following drug should be avoided in the management?

Since this patient, has been taking alcohol every day, at the time of presentation, Disulfiram should be avoided as it may precipitate a severe Disulfiram like reaction. Disulfiram should not be used until person has abstained from alcohol for at-least 12 hours. Also, please remember that phenytoin does not have any role in the management of alcohol dependence. However, this question is specifically asking for the drug that should be avoided and hence Disulfiram is the best answer.
