The phenomenology of Merleau-Ponty in investigations about medication use: constructing a methodological cascade

ABSTRACT Merleau-Ponty innovated when giving primacy to the body and perception in his philosophical proposal. Within the field of health, his thinking gives us access to the knowledge gained from the corporeality of individuals with chronic diseases. The objective of this study was to expand the understanding of phenomena associated with the daily use of medication, which includes increasingly complex drug regimes, through the lens of Merleau-Ponty. To this end, we described the research steps anchored in his phenomenological philosophy and structured them in the form of a cascade, beginning with the definition of phenomenology as a new form of epistemology, existence as a paradigm, and the body as a theory. Furthermore, the methodology included the use of existential structures, namely, time, space, relationships with others, and sexuality, connected through the intentional arc to reach an understanding of the phenomenon of medication use
