Building from the works of Jacques Derrida, this article explores health anxiety’s aporetic relationship with medicine through a deconstructive approach. I argue that attention to Derrida’s writings (and in particular, his readings of pharmakon and autoimmunity) may prove useful in explaining the cyclical character of health anxiety and its ambivalent response to medical reassurance. What’s more, I demonstrate how structuralist interpretations of health anxiety as a signifier without referent prove insufficient within a Derridean account. Such a reading emphasizes the need for interdisciplinary medical humanities as well as critical reflections on the possible limitations of Western medical semiotics.

本文以雅克·德里达（Jacques Derrida）的作品为基础，通过一种解构性方法探讨了健康焦虑与医学的外交关系。我认为，关注德里达的著作（尤其是他对pharmakon和自身免疫的读物）可能有助于解释健康焦虑的周期性特征及其对医疗保障的矛盾反应。更重要的是，我演示了如何在没有德里恩的情况下以结构主义的方式对健康焦虑作为指称的解释被证明是不足的。这样的阅读强调了跨学科医学人文的需要以及对西方医学符号学可能局限性的批判性思考。
