Abstract: Disclosed is a liquid medication dispenser that can be removably attached to various types of bottles or containers. In one embodiment, the dispenser includes a cylindrical reservoir that tapers from a lower end to an upper end thereof. The lower end includes a cap that can be removably attached to a bottle. The upper end includes a lid that can open and close when actuated via a lever on the exterior of the reservoir. The interior of the reservoir includes a spherical valve having a port that extends the diameter thereof. The valve can be rotated via a knob so that the port can be aligned vertically or horizontally, wherein the interior of the bottle is in fluid communication with the reservoir when the port is aligned vertically and the interior of the bottle is blocked from the reservoir when the port is aligned horizontally.
