A pill dispensing cap that secures to a conventional pill container. The pill dispensing cap has a lower cap, a pill discharge port, and a spring loaded rotatable and slidable upper cap. Pills are dispensed one at a time, and the remaining pills are isolated from external contamination. A child resistant lock prevents small children and/or mentally handicapped individuals from easily accessing medicine inside the container. The child resistant lock uses a vertically slidable upper cap that is slidably and rotatably attached to the lower cap. A child safety lock uses a key in the upper cap that must be aligned with a slot in the lower cap to allow a pill to be dispensed. When the key and slot are aligned, the upper cap is vertically compressed against the lower cap. As the upper cap moves toward the base cap, a gravity fed pill discharge port is exposed which releases a single pill.
