If you have histamine intolerance, you may experience worse symptoms after consuming alcohol with a high histamine content. Medication interactions frequently contribute to acquired alcohol intolerance. Drugs like disulfiram, used for alcohol dependence, deliberately interfere with alcohol breakdown. Other medications, including some antibiotics (e.g., metronidazole) and antifungals, can inhibit ALDH2 activity, causing intolerance-like reactions when combined with alcohol. “Alcohol and sulphites tend to evaporate away during cooking, so the potential for intolerances is certainly reduced,” Dr Watts says. However, if you’re allergic to an ingredient found in certain alcoholic drinks, dishes which contain that drink are not safe to eat.
