The problem of the invention is to so develop known dispensers, that it is possible to very precisely determine the actual discharged medium volume.A dispenser according to the invention has a media path, which leads from a medium storage container to a discharge opening. A delivery device for delivering medium is located in said media path. The media reservoir stores a medium, particularly a fluid, which preferably incorporates at least one pharmaceutical substance. A media discharge can be brought about by means of an operating means. According to the invention, on the dispenser is provided an electronic detecting device for detecting a quantity representing the amount of medium discharged.
