Background
- Disulfiram (Trade names: Antabuse, Antabus) - causes an acute reaction in the presence of ethanol.
- Works by inhibiting acetaldehyde dehydrogenase → buildup of acetaldehyde → unpleasant effects.
- Designed to assist in alcohol cessation.
Disulfiram-like Reaction
- Certain other medications cause acute ethanol intolerance and similar effects as disulfiram[1]
- Mechanism is thought to be the same (i.e. buildup of acetaldehyde)
- Examples
- Antibiotics (metronidazole, certain cephalosporins, chloramphenicol, furazolidone)
- Antifungals (Griseofulvin)
- Quinacrine
Clinical Features
- Nausea/vomiting
- Headache
- Visual changes
