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, – I am appalled to find that there are now two 'over-the-counter' S3 medications bearing the Sudafed label which do not contain pseudoephedrine. The first is Sudafed PE tablets, the second Sudafed nasal spray.
The new products contain phenylephrine, which is an active vasoconstrictor and decongestant when administered intravenously or intranasally, but its efficacy in a per-oral tablet formulation is questionable, as most pharmacological data suggest its first-pass metabolism is almost complete.
My family's experience in using these tablets confirms this. Indeed, I was so appalled that I returned the Sudafed PE tablets to the pharmacy where purchased, pointing out that they were not as labelled.
Sudafed has been a registered, recognised name for pseudoephedrine for more than 40 years, so to have it used for a completely different compound is confusing and misleading. How can the Therapeutic Goods Administration justify allowing the misuse of this name? What data were submitted to justify using the Sudafed label on products which do not contain Sudafed?
