Pillbox-US National Library of MedicineThe Pillbox website was developed to aid in the identification of unknown pills (oral solid dosage form medications). It combines images of pills with appearance and other information to enable users to visually search for and identify oral solid dosage form medications. Once a pill has been identified, additional information is provided, including brand/generic name, ingredients, and the National Drug File identification number. Links are provided to NLM drug information resources, such as drug labels from DailyMed and the Drug Information Portal, which searches NIH and FDA drug information resources. As of March 2014 Pillbox contains 5,364 pill images. These images cover about half of the prescription medications available in the United States.
