This article discusses the question of access to medication as a social right, investigating how users registered in the Hiperdia program perceive their access to medication. To achieve this, the process of "medicalization" experienced by Brazilian society today was assessed, highlighting the influence that this process has on access to medication, prejudicing the achievement of universal and equalitarian access. Using a technique recommended by qualitative research, focal groups with Hiperdia users in the basic health service of Juiz de Fora, Minas Gerais, Brazil, were set up. The survey emphasizes the perception that these users have with respect to their rights related to essential medication. In this process, their beliefs, knowledge, attitudes, difficulties, fears, doubts and anxieties concerning the use of essential medication are investigated, as well as their viewpoints on the disease(s) they suffer from. Among the results obtained, it was revealed that the majority of the users of basic health units do not consider that they have rights and that access to medication as a constitutionally-assured social right is far from being implemented in the Brazilian public health service today.
