Heavy metal exposure is a public health concern. This review examines the appropriate and inappropriate uses of chelating agents for heavy metal toxicity and testing.

Area of Science:

  • Toxicology
  • Pharmacology
  • Public Health

Background:

  • Heavy metal exposure from food and environment poses significant public health risks.
  • Chelating agents enhance the elimination of excess metals but have limited approved uses.
  • Adverse effects and inappropriate application for diagnostic testing are concerns.

Purpose of the Study:

  • To review the appropriate clinical applications of chelating agents.
  • To highlight the problematic and abusive use of chelating agents for heavy metal testing.
  • To raise awareness regarding the correct and incorrect uses of these drugs.

Main Methods:

  • Literature review of chelating agent applications.
  • Analysis of approved clinical indications versus off-label use.
Keywords:

  • Discussion of heavy metal toxicity and diagnostic challenges.

    • Main Results:

    • Chelating agents are approved for specific, severe metal overload conditions.
    • Widespread inappropriate use of chelating agents for diagnostic purposes was identified.
    • Potential adverse effects associated with misuse were noted.

    Conclusions:

    • Emphasize the limited and specific indications for chelating agent therapy.
    • Discourage the use of chelating agents for routine heavy metal testing.
    • Promote responsible prescribing and patient education regarding chelator risks and benefits.
