An indicating means in a dosage dispensing device for medicaments, particularly a dosage inhaler which indicates a number of dosages administered from the dosage dispensing device. The indicating means includes a rotatable disc (1) having apertures (2) passing therethrough which can be filled with a medicament in particle form. By rotating the disc the apertures can be brought into an air channel or duct (3) through which air is inhaled. The rotatable disc has associated with a central portion a spiral groove or ridge (4) which can engage with peripheral teeth (8) on a toothed wheel (6), such that rotation of the disc (1) results in rotation of the toothed wheel and the toothed wheel is provided with one or more markings (9) which are visible from outside the dosage inhaler upon rotating the disc a predetermined number of times.
