A tonic with rather unpleasant side effects

Abstract

A case study of patient with a fixed eruption due to quinine contained in Tonic Water is described. Fixed eruptions are uncommon but not rare. They are usually not difficult to diagnose once the possibility is considered. A long and detailed history with subsequent re challenging (orally) with the suspected offending agent offers the best means of diagnosis although a 48 hour occlusive patch test at the site of the eruption sometimes may also be useful. Patient was advised to avoid all quinine containing beverages.
