Present evidence for dark matter in our Galaxy and in the Universe at large does not exclude the possibility that the dark matter particles could be unstable. If this is the case, their decays into positrons, antiprotons or gamma rays might occur at rate sufficiently large to allow the indirect dark matter detection through an anomalous contribution to the high energy cosmic-ray fluxes. We discuss in this talk the constraints on the dark matter lifetime from various observations and the prospects for future detection.
