Can Antabuse cause false breathalyzer tests?

Antabuse (disulfiram) itself does not typically cause false positive results on breathalyzer tests. However, it works by inhibiting the metabolism of alcohol, leading to unpleasant reactions if alcohol is consumed. If someone has consumed alcohol shortly before a breathalyzer test, the presence of acetaldehyde (a byproduct of alcohol metabolism affected by Antabuse) could potentially influence the results, but this is not common. Always consult with a healthcare professional for specific concerns regarding medications and alcohol use.
