Use & Instructions

Intended Use & Instructions

Intended use of this colorant is for limited-exposure diagnostic swallow studies only (Bedside Swallow Evaluations on tracheotomized patients, Fiberoptic Endoscopic Evaluation of Swallowing, post-laryngectomy studies by Speech Pathologists and ENTs). Not intended for use in high-exposure enteral tube feeds.


  • Gently twist and remove tab.
  • Place a few drops at a time into the bolus until the desired color or hue is achieved via conventional mixing (stirring or shaking)
  • For dark, navy blue color, add to foods and liquids with a more neutral pH (water, dairy products, cookies, crackers, etc.). The color contrast will turn bright fuscia or magenta in foods and liquids with a more acidic pH, and turn green in foods and liquids with a more alkaline pH, providing potential for additional diagnostic information.
  • Store in a cool, dark place, out of direct sunlight or refridgerate.
