The Family Health Program (PSF) constitutes a strategy for reformulating the health assistance model in Brazil. This study was carried out to ponder over the challenges of this strategy concerning to health practices in the primary care context. After existing for more than twelve years, there appear questionings related to the paper of PSF in the reformulation of the way to think and promote health, and their structures remain permeable to the traditional hegemonic model that corrupts the daily work process. Some changes and reconstruction are necessary in the health practices concerning to care production based on light, relational and integrate technologies that are centered on users' needs. Although the deconstruction/reconstruction process implicates much labor, the advantage in overcoming the challenges faced by PSF rather leads to the transformation of reality and to construction of health practices that are solidary, welcoming, and resolvent.
