Disulfiram-like reactions with newer cephalosporins: cefmenoxime.

A 54-year-old woman with recurrent adenocarcinoma of the uterus was treated with new third-generation cephalosporin, cefmenoxime, for a urinary tract infection. She received an alcohol-containing tylenol elixir while receiving the drug on two occasions. A disulfiram-like reaction was noticed each time. Such reactions have been described in patients receiving certain drugs such as 5-nitroimidazoles, nitrofurans, sulfonylureas and certain newer cephalosporins with a methyltetrazolethiol side chain. This is the first report of a disulfiram-like reaction with cefmenoxime. The mechanism, causes, and significance of disulfiram-like reactions are discussed.
