The invention relates to a method and a device for lyophilizing, reconstituting and administering a reconstituted substance. The device has an elongate housing comprising a dispensing-side front housing end and a housing end lying opposite it. A first chamber with a lyophilizate contained in it is disposed in the housing in the region of the front housing end, which is tightly sealed at its end facing the front housing end by means of a removable closure and in the direction of the rear housing end by means of a plunger. A second chamber is provided or formed in the housing in the region of the rear housing end, which is connected by means of at least one opening to the ambient atmosphere. This opening is closed by a membrane which is permeable to gas but not to bacteria.
