A system and method for altering the scent within a pill organizer. The pill organizer has multiple pill compartments and a scent compartment within a container housing. One or more perforated walls separate the scent compartment from the various pill compartments. A scent source that releases scent is placed in the scent compartment. The scent permeates into the various pill compartments. When a pill compartment is accessed by a user, the predominant scent perceived by the user is that of the scent source. In this manner, the user is not dissuaded from consuming pills, soft gels, tablets, gummies and / or capsules due to the odors that such items may release. The scented source can be replaced and / or renewed within the pill organizer. As such, the effectiveness of the overall product can be maintained for the life of the product.
