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

Editor, – Apropos Dr John Watson's comment on new drugs (Aust Prescr 1999;22:29), this dictum of my old professor has helped me in over 50 years of practice:

'Be not the first by whom new drugs are tried, Nor yet the last to lay the old aside'.
