Instructions for Disposing Medical Needles (Sharps)

  • Sharps should be stored in a strong, leak proof plastic container, such as a laundry detergent bottle.
  • The container should be clearly marked “BIOHAZARD”.
  • When the container is full, it should be filled with one part bleach and ten parts water and allowed to soak for 20 minutes.
  • The solution should then be poured into a sink, and the container should be sealed with its original cap. As a safety measure, heavy duty tape should be placed on the cap
  • Dispose of the container in your regular household trash.

Prescription Medication Take Back Events

The Kauai Police Department hosts medication drop boxes through the Hawaii Medication Drop Box Program. Boxes are located at the Kauai Police Department Headquarters in Lihue at 3990 Kaana Street. The program will supplement the drug take back events that the state and federal law enforcement plan to continue twice a year.

The Drug Enforcement Administration coordinates bi-annual take back events for expired medication. Events are tentatively scheduled for the 4th Saturday in October and April of each year. Events are at Kauai Police Department Headquarters from 10 am to 2 pm.
