Safe Disposal of Unwanted Medications

How to Safely Dispose of Unwanted Household Medications


Don't flush your drugs!  Flushing unwanted and expired medications down the toilet is the least desirable of all disposal alternatives.  Wastewater treatment facilities are not equipped to remove all traces of pharmaceutical chemicals.  If you flush your drugs, a portion of those contaminants will reach local waters.  Scientific studies show the chemicals in many drugs can harm aquatic life. Proper disposal of unwanted medications helps protect your family, your community and the environment.

  • Keep Pollutants out of our water - Research has linked pharmaceutical pollutants to reproductive defects in fish, resistance to antibiotics, and the development of drug resistant germs.
  • Prevent accidental poisonings - Many children and the elderly are often victims of accidental poisonings due to medications in the home.
  • Reduce drug abuse and illegal use - More teenagers abuse prescription and over-the-counter drugs than any illicit drug except marijuana.

 Here Are Ways to Safely Dispose of Unwanted Medications
