What flavoring should a patient taking Antabuse be cautious about due to potential alcohol content?

Patients taking Antabuse, which is also known as disulfiram, must be cautious about consuming any products that may contain alcohol, as these can trigger adverse reactions when combined with the medication. Vanilla extract is often a common concern because it can contain high levels of alcohol, typically around 35% by volume. Even though it is used in small quantities in food preparation, it could potentially lead to a reaction in someone taking Antabuse.

In contrast, chocolate syrup, maple syrup, and honey do not generally contain significant amounts of alcohol, making them safer options for someone on this medication. Therefore, awareness and caution regarding flavorings and extracts containing alcohol, specifically vanilla extract, is critical for patients on Antabuse.
