Tap (draft) beer and monoamine oxidase inhibitor dietary restrictions.

OBJECTIVE

Traditional monoamine oxidase inhibitors (MAOIs) continue to play an important role in the management of a wide variety of clinical conditions. Accordingly, a practical and safe approach to MAOI dietary restrictions remains an essential component of patient management.

METHOD

In an effort to refine MAOI dietary recommendations, we report a case of hypertensive crisis following the consumption of a modest amount of tap beer.

RESULTS

A well-documented case report involving tap (draft) beer consumed while on an MAOI supports an earlier study, which recommended that all tap beers be restricted on MAOI diets. The 2 cases were remarkably similar in terms of the offending substance, quantity consumed, and subsequent reaction.

CONCLUSIONS

As a result of recent tyramine analyses and 2 well-documented case reports, all tap (draft) beers should now be absolutely restricted on MAOI diets because they represent a very significant risk at modest levels of consumption.
