Enteral Nutrition Formula Guide

With the vast number of enteral formulas on the market, it can be difficult to know which formula is right for your patient. Factors to consider include:

  • Age
  • Fluid status
  • GI function
  • Food allergies
  • Diet preferences

Most patients can tolerate a standard formula1 and specialty formulas usually require documented medical justification for use in the home setting, due to increase in cost. However, there are situations in which a standard formula may not be tolerated and one must consider other options. Most institutions have an enteral formulary, which may need to be considered when choosing a formula as well.

Information in this guide was obtained from formula company websites. Currently, there are no formalized definitions for formula categories, therefore formulas are grouped by reimbursement codes, called HCPCS codes, when applicable. Claims such as gluten free, lactose free, non-GMO and organic should be reviewed with each company before use. This guide is reviewed on a regular basis for updates, however products frequently change and new products are constantly entering the market place. Therefore, this guide may not be all inclusive. It is meant to be a tool that can guide you toward a formula that is best for your patient. Ultimately each patient’s nutrition needs should be considered individually. This listing includes most enteral formulas in various categories for use. Please refer to the manufacturer’s website for the most up to date product information.
