Causes of Disulfiram-Like Reaction

The Disulfiram-like reaction is caused by the inhibition of aldehyde dehydrogenase enzyme activity, which leads to the accumulation of acetaldehyde in the body. This accumulation is responsible for the symptoms associated with the reaction.

The reaction can be triggered by various factors, including:

  • Medications: Certain medications, such as metronidazole, cephalosporins, and some sulfonylureas, can interfere with aldehyde dehydrogenase activity, leading to a Disulfiram-like reaction.
  • Alcohol: Consuming alcohol while taking medications that trigger the reaction can exacerbate the symptoms and severity of the reaction.


Disulfiram-like reaction can be triggered by several medications that inhibit the enzyme aldehyde dehydrogenase, leading to an accumulation of acetaldehyde in the body. Some common medications that can cause this reaction include:

  • Alcohol
  • Metronidazole
  • Tinidazole
  • Cefotetan
  • Cefoperazone
  • Cefamandole

These medications interfere with the normal breakdown of acetaldehyde, resulting in its accumulation and causing symptoms similar to those experienced by individuals taking disulfiram.
