Clients on disulfiram therapy (alcohol-aversion therapy) must carefully avoid all alcohol-containing products, including medications like cough syrups, personal care items such as mouthwash, aftershave and perfume, household items like vinegar and cooking wines, and topical compounds including rubbing alcohol. Reading ALL product labels is important, as even tiny amounts of alcohol can trigger severe reactions like nausea, vomiting, headache, and respiratory distress.
