Pill Identifier provides the ability to identify pills from the nation's prescription formulary based on their physical characteristics (i.e.) color, shape, imprint and scoring. Pill Identifier also provides consumer friendly as well as clinical information about the pill.

Consumer friendly information is provided by linking search results to MedlinePlus and to the clinical and brand names of interacting drugs as provided by NDF-RT. Clinical information is provided by linking search results to the Structured Product Label (SPL). Drug labeling and other information in the SPL is what has been submitted by drug companies to the Food and Drug Administration (FDA) as drug listing information. The SPL is provided by DailyMed.

The database of pill images is provided by the National Library of Medicine's Office of High Performance Computing and Communications (OHPCC). The work of the OHPCC is ongoing.

Filters
Filters are search criteria used to limit the number of images returned as a result of a search. There are four filters: Color, Shape, Imprint and Score. Enter as much information as you have about the pill. It will reduce the number of images returned and speed up your response.

Color:	The color of the pill. Select the closest match. This is a required field. Tip: If a pill is of multiple colors, select a color that matches the dominant color of the pill. If there is no dominant color, select a color that matches any of the pill's colors.
Shape:	The shape of the pill. Select a shape that best matches the shape of the pill. This is a required field.
Imprint:	The physical imprint present on the pill. Imprint elements should be separated by a comma. To search for pills without any imprint, use the value no-imprint. Tip: Leave Imprint blank if you do not recognize the imprint or you do not want to filter the results based on imprint. Tip: The Imprint filter also works on partial imprints. Therefore, enter as much of the imprint as you have available; even if it is only a single character.
Score:	An integer value specifying the number of equal sized pieces that the pill may be cut into. Tip: Leave Score blank if the pill cannot be cut or you do not want to filter based on score.
