Medicines help treat diseases, manage chronic conditions, and improve health and well-being for millions of Americans. It is important that patients take their medicines as prescribed by their health care provider. However, if you have expired or unwanted medicines or sharps, proper disposal is important and easy.

Tossing sharps (injection needles) and medicine in the trash can poison or injure people and pets. When disposed of down sinks or toilets, these materials can also cause pharmaceutical pollution in the San Francisco Bay or injury at wastewater treatment plants.

There are various community kiosk drop-off sites that allow patients to properly dispose of their expired or unwanted medicines or sharps. Click here for a full list of drop-off locations.
