A liquid dosage dispenser includes a bottle and a dispenser apparatus supported on the bottle having a housing extending into the bottle and a plunger device extending into the housing for longitudinal movement therein. The housing includes an opening through which liquid in the bottle can be drawn into the housing, with one of the housing and plunger device including a stop system of predetermined configuration and the other of the housing and plunger device including a follower for contacting the stop system. The plunger is rotatable with respect to the housing to align the follower with a desired portion of the stop system, with the follower and stop system, when aligned, allowing the plunger to be moved longitudinally along the housing until the follower contacts the stop system to draw a predetermined amount of liquid through the opening into the housing. The dispenser is removable from the bottle to allow the predetermined amount of liquid to be dispensed through the opening.
