An aerosol dispenser for use with an aerosol vial. The dispenser contains an assembly that indicates the quantity of doses dispensed from or remaining in the aerosol vial. The assembly comprises a rotatable indicator comprising a circumferential rack that is engaged by a worm-gear. Reciprocal movement of an aerosol vial within the dispenser causes rotation of the worm-gear which in turn causes rotation of the rack.
