U.S. Geological Survey studies have found hormone medications, antidepressants, and antibiotics in waterways nationwide from medicines in human waste and disposal of unwanted drugs down sinks and toilets. Scientists are studying the possible impacts on humans and marine life when exposed to these drugs, but you can minimize potential problems by safely disposing of unused medicines.

Dispose of medicines safely:

 
• Never put medicines down sinks or toilets
• Bring unwanted or expired medications to one of the disposal locations in the Bay Area.
