String containing one or more desired pill characteristics.

An input string may contain any of the following:

  • NDC (9, 10 or 11 digit, with or without dashes)
  • Imprint
  • Shape
  • Color
  • Brand Name
  • Generic Name
  • Active Ingredient
  • Inactive Ingredient


This parameter will automatically parse a given input string to generate a results set of pills containing the desired characteristics. No other physical (e.g. shape, color etc.), or pharmaceutical (e.g. name, inactive etc.) defining parameters are required. With this powerful parameter, a fully featured pill image search can be quickly integrated into an application with just a single input line from the user.
