Medication Disposal

Safely disposing of unused or expired medication protects you, your family, and the environment. Here are some ways you can safely dispose of your unwanted medication including prescriptions, vitamins, and over-the-counter medications.


  • Deposit unused medications (no liquids) 24 hours a day, seven days a week in the permanent drop box at the Cambridge Police Department, 125 Sixth St. The drop box is located in the first floor lobby, near the Records Unit. For a list of accepted items and other information, visit the police department’s medication drop box web page.
  • Mail your medications for free to a company that properly disposes of unused medications in accordance with EPA regulations. The free mailers are available at:
    • The Cambridge Public Health Department, 119 Windsor St. (ground level). Mailers can also be sent to you upon request by contacting Mary Kowalczuk at 617-665-3865 or mkowalczuk@challiance.org.
    • The Citywide Senior Center (front desk), 806 Massachusetts Ave. in Central Square.
    • The North Cambridge Senior Center (front desk), 2050 Massachusetts Ave.
  • Cambridge police officers will accept unused medications at the Department of Public Works’ four scheduled Household Hazardous Waste Collection events. Ask for the medication drop-off area when you arrive at the HHW disposal event. For more information, visit the DPW Household Hazardous Waste Collection Day web page.
  • To dispose of medication in syringes, please use the sharps collection box at the Cambridge Public Health Department (lower lobby, 119 Windsor St). or the Cambridge Police Department.
  • To dispose of liquid medications, mix with any absorbent, unappealing material (such as kitty litter or sawdust) and place in a sealed plastic bag before tossing in the trash.

The city’s medication disposal initiative is a partnership of the Cambridge Police Department and the Cambridge Public Health Department.
