The Editorial Executive Committee welcomes letters, which should be less than 250 words. Before a decision to publish is made, letters which refer to a published article may be sent to the author for a response. Any letter may be sent to an expert for comment. When letters are published, they are usually accompanied in the same issue by their responses or comments. The Committee screens out discourteous, inaccurate or libellous statements. The letters are sub-edited before publication. Authors are required to declare any conflicts of interest. The Committee's decision on publication is final.

Letter to the Editor

Regarding my previous correspondence (Aust Prescr 2008;31:88-9), I suppose one has to accept the Americanism 'sulfur', but this applies to chemical 'sulphur' as used in dandruff preparations. When sulphonamide preparations first came on the market they were conveniently referred to as 'sulfa' drugs and therefore allergy to these drugs is 'sulfa' allergy and not 'sulfur allergy' as your article stated.
